Intel Pentium G3258 bottleneck R7 265

It shouldn't. Even if it does, you can overclock that one to help relieve any overclocks.

Most likely, depending on your RAM and Windows versions.

Yes it will at stock settings. If you have the ability to OC it then the answer changes to no it wont. The issue is it is a low end CPU at its stock settings and the reason they get on the Toms Gaming CPU list is because it can OC. With the OC it can rival some i3 quad core CPU's but this is only when OCed. When its performance is upped it will not bottle neck that selected GPU.

Once again at stock settings Yes it will bottle neck. OCed no it wont.

OCing voids any and all warranty's for that piece and motherboard by the way.

just some extra info, Windows versions have no control over bottlenecks. It is strictly a Hardware issue.

32 bit versions won't restrict your hardware? News to me.

no it wont the 64 bit OS has more to do with the way the programs are written to interact with the OS. It will allow the alocation of more memory to be used. A 32 bit program will run the same on a 32 bit OS as on a 64 Bit OS. the difference is if the program is a 64 bit program. It can onlt operate properly on a 64 Bit OS.

the OS has nothing to do with CPU, GPU, Motherboard, PSU, HDD/SSD, Optical drive. It does however limit the amount of ram (amount of usable GB) that can be allocated.


@ OP yes even at stock it will bottleneck. the only way you can relive a bottle neck with that CPU is OC it and this would mean, as of right now, getting a Z series chipset motherboard. Not a budget motherboard. Yes some company's are putting out Bios updates to "some" motherboards to give them the ability to change the CPU multiplier but this will be a hit or miss feature for some time till they release a cheap OCing motherboard geared toward the Pentiums.

Yes, but it will restrict you RAM to 3.5 GB, which will cause a RAM bottleneck. That includes VRAM as well. That's a massive restriction, especially at a higher resolution.
My system is currently using 2.8 GB, and I don't have much running. That leaves less than a GB of memory for a game, including Vram.
Obviously; Windows will manage the memory different if less is available.

A 32 bit application can still use more resources in a 64 bit environment, because the OS restrictions won't restrict the application either. I am surprised you are even defending your statement, it seems like a logical question to ask.

This is a big factor in the bottleneck regarding a videocard a low end processor, on what I assume is Dell or HP desktop; especially considering the GPU's VRAM will be impacted by the limits of a 32 bit environment. That could easily cause a bottleneck.


I don't agree with your logic and the question still deserves an answer.

How much RAM do you have, and what version of Windows are you running?

OP's question has nothing to do with ram. IT has to do with CPU and GPU. Will the CPU be able to feed the GPU enough info to not bottle neck the card. no matter if it is a 32 or a 64 bit OS it will bottle neck. Your questions really don't apply when it wont matter either way.

A 32 bit OS is able allocate 3 GB of system ram and 512 MB of Vram. The bottleneck with to little ram comes into effect IF you want to game. Anyone building or purchasing a gaming PC will Opt for the 64 bit versions. It is well known that anything less than 4 GB you shouldn't game on. If purchasing a vid card your doing one of 2 things, Gaming or video editing. Now since the CPU is really weak for video editing it can be asumed this will be a Gaming and everyday machine. 4 GB is usually the minimum any manufacture will put in a machine. on top of this the Pentium G3258 is a bran new release CPU it is easy to conclude this system is not built yet. the majority of windows OS's sold are 64 bit versions now becaise the price of ram has dropped so much that it is cheaper to buy 4 GB than the old 2 GB sticks.

for a few years I gamed on 3 GB of ram but as hardware and games advanced through ddr, ddr2 and ddr3 with prices dropping it was easy to go to 4 GB then 8 GB.

I will defend my statement that in this case the OS will make no Hardware Bottlenecks before the CPU does. heck even my cheap laptop came with win 8 64bit. It is becoming standard now. 32 bit OS's are more for tablets and smart phones that don't have tons of system memory and resources.

That's a lot of assumptions.

If OP posted his hardware configuration and Windows version, we could make some educated guesses.

Unfortunately; you seem more interested in a flame war than gathering the required information.

OK I'm done trying to explain my position to you, point is that CPU and GPU will be bottle necked. I am not flaming anyone nor you just trying to state facts and if necessary will post links to prove my points. It is not flaming when I am not attacking anyone just trying to prove my point.

I am asking for information. Like.. how much RAM are you using, what version of Windows are you using?

You know... basic information anyone should get before they troubleshooting anything.

In your opinion will ram stop or start the CPU from creating a bottleneck when it comes to a GPU?

I'm not sure. I didn't ask what he plans on doing with his computer yet
What game he wants to play, or program he wants to use.
What motherboard he has.
If he already bought the card and if he's experiencing any issues or if he's planning on purchasing the card.

I like to ask questions before I make assumptions.

Well I can give you the answer from a hardware point. No it does not. The question posed is and I quote "Will a Intel Pentium G3258 bottleneck an R7 265". Not that there are issues to troubleshoot, other parts to question. All parts work together BUT the CPU feeding info to the GPU has very little to do with the ram when we are talking about a low end budget CPU. in this case you need to consider how much info it can process. How much info can be taken in and feed out fast enough to not end up being locked at lets say 25 FPS in a MMO but other people with the same card and better CPU are getting 100 or more. <-- this was a hypothetical situation that actually happens in real word scenarios and is an exaggeration to what the OP could see but a representation to show how a CPU bottleneck presents itself. Yes the speed of the ram and amount can effect FPS but to answer will the CPU bottle neck a certain GPU the ram is not considered in to the equation.

no assumptions in the answer that the low end NEW Pentium at stock will bottleneck the GPU. If OCed it will be fine. no assumptions there because ram, HDD/SDD, PSU, motherboard optical drive and OS do not play a part in will the equation.

RAM has such a small effect on performence unless your maxing out the ram, the issue is, the pentium at stock clocks is not that fast and needs to be overclocked.

I disagree with both of you.

It depends on the game they are running.

If they have over 4 GB of RAM on a 64 bit OS, and they aren't playing anything super CPU intensive, the GPU will probably be bottleneck. These benchmarks are done a Titan, and only Metro and BF4 really show strain.

It averages over 60 FPS in most games with a GTX titan, according to Toms.

You won't hit a major bottleneck on a mid-range GPU.

These Benchmarks are using a 6GB GTX Titan, and the Pentium is only about 5 FPS lower than an i5 4690 in Battlefield 4.

Assuming you have 8 GB of decent RAM and a 64 bit OS, you will bottleneck on your GPU.

If you have any numbers that aren't assumptions, feel free to post them.

lets take a game out of you link, Arma III, for an example. Arma III is notorious for being CPU bound. The Pentium averages 47-48 FPS. "ON A TITAN" what do you think is going to happen to those numbers when you pare it with a medium gaming card? No assumptions, they will drop dramatically. Also do you honestly believe the Athlon and Pentium tested did not bottleneck that GPU? A titan GPU? of course there is a bottleneck It is the stock settings that will cause a bottleneck not the OCed as much.

lets look further in to the story by one maybe 2 pages to grid 2, lets look at frame times, although all CPU's did well with a Titan where are these numbers going to be with a mid range card? the frame times show that the Intel Pentium is suffering big time because it can't keep up even OCed. It is a much better buy than the athlon but can not feed a titan. just because you can put a titan in a PC with old Pentium 4 doesn't mean it should be done.

As proof of there being a major bottle neck with the titan lets look even deeper in to the story to there run of 3DMark shall we? For the graphics scores lets look who sits at the bottom even though the program puts as much as possible to GPU the CPU still plays a part. The physics scores don't need to be mentioned because this is just a measure of the CPU's against each other but lets look anyway, In any game that is CPU intensive the Pentium will hold you back.

to show the jump in performance you get with OCing it lets go to Toms Blender test shall we? Here we all can see the CPU gains great strides once OCed but still in the range of an "i3 CPU" this part I want to get through to every one. i3 CPU's are OK for mid range GPU gaming but not much more than that for gaming. now with this in mind this CPU, the Pentium G3258, only comes close to the i3 when OCed.

this is an excerpt out of this months best gaming CPU article. This is found right on the first page:
Although the Pentium is a dual-core architecture lacking Hyper-Threading, Haswell's excellent efficiency earns the Pentium a low-budget gaming CPU recommendation as a result of Chris' findings. My only hesitation comes from the fact that Intel's most affordable platform controller hubs aren't designed to enable overclocking, forcing you into a more expensive Z87 or Z97 Express-based board. With that said, several manufacturers have started slipping out BIOS updates for their B85/H81/H87/H97 offerings with multiplier tuning tweaks. Some of those products sell for under $60. They're not supposed to be doing that, but we'll see how the saga plays out.

now as I have said already in this thread, in order to OC you need a Z-series chipset to guaranty the ability to OC. OK that section was just to say Don't buy it and not get the proper board. other ways you will see a bottleneck.

your BF4 and metro part of the coment, BF4 hit a GPU bottleneck this is why all scores were so close, but Metro hammered the Pentium. bottlenecks usually are program specific or genera specific. this is why in my last comment I mentioned the MMO's they are usually more CPU intensive than GPU. I would love to see this CPU in GuildWars 2 and try to pull the numbers it does in Wow in this benchmark.

I have read this article the day it was published and as impressive as the new Pentium is I think it will bottleneck a mid range card. Since I'm on a roll with mu opinion I might as well add this small tid bit, It cant hold a candle to FPS I pull with my system in all the games I like to play. some yes some no but I want 1920x1080 full HD ultra settings. BUt then again we are talking a low cost very efficient CPU on the other hand is a budget no brainer. I just wouldn't pare it with that GPU. a R7 250 yes but no higher. If you do it will pay to get a better CPU. \

OK lets put a little contrast on this shall we? So far we have looked just at what Toms Hardware used for benchmarks and there system setup. Lets look a little deeper into other systems set ups. http://www.bit-tech.net/hardware/2014/06/24/intel-pentium-g3258-review/1 THis system was set up using a Nvidia GTX 680, equal to and is a GTX 770.

In GIMP it held up well But when handbreak fond its way on to the system the Pentium crumbles to the likes of an i3 2100 CPU. not surprising from what we have seen here on Toms benchmarks.

In skyrim at stock CPU speed you are playable but then again we are talking a GTX 680 here holding 51 FPS minimum.

lets look a shogun, this game is what I have been talking about. not this exact game but ones like them. A game that uses the CPU as much as the GPU. on default settings you get 16 minimum and an average of 21 at stock CPU settings now OC it and we get 25 minimum and an average of 30 FPS. this shows that take out that Big GPU out of the question what can the CPU realistically do? OK it can do a lot this point to what I have been saying it is a low end CPU and to pare it with a mid range card is its best bet for performance but if you go to high in the mid range you will end up with a CPU not being able to feed the GPU. Once the CPU gets stressed it can not keep up and feed the GPU info causing a bottleneck. we have seen that the physics scores are low for this CPU. Physics is mostly done on CPU so in an instance of High physics action like a building falling down and explosions the CPU will buckle and you will have lag. even with a Titan strapped to its north bridge.

to add more contrast to this http://hexus.net/tech/reviews/cpu/70977-intel-pentium-anniversary-edition-g3258/?page=7

at the bottom you see a graph where a GTX 750ti was parred with this CPU. the GTX 750ti is just above teh R7 250 so lets say about the R7 260 range. It offers playable frame rates but still will choke in heavy CPU games. Averaging less than 60 FPS is OK for some but just not my taste.

If this is your CPU of choice don't play heavy CPU demanding games.

The number at the top is the MINIMUM FPS, the number in gray is the AVERAGE

The AVERAGE FPS in Skyrim was 103 FPS. Well over 60 FPS, and most likely not achievable on the R265 on Ultra at 1080P.

Good try. You will certainly get less frame dips, better loading times, etc etc from a faster CPU, but you will not bottleneck on the Pentium in most (not ALL) games.

Skyrim is a horrible example of a CPU bound game anyway, considering the 8 core FX-8350 scored well below the Pentium.

Do you have any facts to back up your assumptions? That was a lot of wasted breath on your part.


The average FPS in Shogun is 21, but the Average on most of the low end i7's is near 31, so clearly CPU isn't going to make much improvement there either. Obviously that game won't run well on 1080, even on the best hardware. The GPU is the Bottleneck in this example.

Wtf are you talking about?
It got the example same FPS as the i7 with a 750 Ti. Did you READ the table?

This conversation is done.

I didn't say skyrim was CPU bound did I? NOPE and IF you reread it with out a subjective eye my post also says the 51 FPS was " minimum". what is your reason for shogun? since you seem to have the higher than though attitude right now? explain that, that conveniently got left out. and please reread it as your comprehension seems to be dwindling tonight, assuming from lack of sleep. I also add a link to games on a mid range card. there is some proof.

Sorry man, all your examples prove the Pentiums performance is GPU bound up to 780 performance levels.

The 750 ti on the i7 had the exact same FPS as the Pentium.

Quote:

The overclocked chip does a very good impression of a Core i7-4770K - there's very little difference in real-world games run at 1080p. Sometimes numbers can be misleading, but the game(s) felt smooth and fluid to play. We'd challenge anyone to tell the difference between the overclocked Pentium G3258 and the 5x dearer Core i7-4770K in these games. Really, the standard chip is good enough for 1080p gaming.

"This game clearly relies on CPU power, and you need a Sandy Bridge-based Core i3 at 3 GHz or a Phenom II at 3.5 GHz to provide a minimum 30 FPS."

http://www.tomshardware.com/reviews/skyrim-performance-benchmark,3074-9.html

31 FPS on an i7 is not playable, neither is 21 fps. 10 FPS isn't a huge leap, especially when nether is a playable example.
In a CPU bound benchmark, it's pretty obvious that the faster CPU will win. However; this benchmark isn't a real world example, it's simply a benchmark for comparing CPU's. If you put the 780 back in, they will all be well over 60 again.

"We use the built-in CPU test, launched by right-clicking on the game in your Steam library. This stages a scripted battle, where we watch the action at a reasonably zoomed-in level. We leave the detail settings at default and record the action for 60 seconds using FRAPS.'

It's a CPU test, not a performance test, afterall.

You should read a bit more carefully.

Here is what we have so far determined:
1. The Pentium is not as fast as an i7 in CPU bound Shogun 2 Benchmarks, although it keeps up with an i5.
2. The 780 and Titan will Bottleneck this CPU.
3. The 750 ti will give the same performance on this chip as it will for an i7 in at least 3 examples.

to be continued midnight here.

Numbers speak for themselves. That Pentium will do fine with an R7 265 assuming you have at least 8 GB of RAM and a 64 bit OS (which all of the examples do have at least, obviously).

If you are using 4 GB or less, you will probably experience some slow downs and performance issues.
