Will AMD Athlon X4 740 bottleneck a R9 270X?

Solution


I think if you bumped the processor up to a 750-760K and overclock it you would be fine. But with those games you may make out alright on your CPU.

The games I would play on said system would be: Star Citizen, Hawken, Planetside 2 and a few others that don't need much to run. Oh and 1080 but I am willing to go down all the way to 720 if the game will run that way.

Thanks, If it matters the setting I care about most is Anti-aliasing and as far as I know thats a GPU-side thing.

Not sure about Hawken, but Star Citizen needs a decent amount of CPU power, and Planetside 2 is an extremely CPU intensive game. I really would not go as low as an anthlon 740 when playing games like that.

What exacly would this low power cpu affect though? Physics?

In those games, it heavily affects the FPS, especially since they are MMOs, a category notorious for its CPU dependency, so you may be fine when walking by yourself, but once you get into a firefight, you will be lucky to get 20fps, and that is just with a dozen people shooting at once. Planetside 2, with its huge amount of players, will become a slideshow.

I meant more along the lines of what part of the game the cpu would be responsible for?

Physics, shadows, amount of players before FPS tanks, things like that

I'm not going to quote that as the quote was getting too big. I don't really care about realistic physics or accurate shadows. Can't I just turn those settings to Very Low and enjoy the game with the rest on high-ish?

Most likely not on high. Before it was optimised, Planetside 2 had people on i7 4770Ks OCed to 4.7ghz playing at 20fps~ during big firefights, and even though it is better now, it really needs a better CPU for the big battles. I would say get something like an i5 (non-k to save money) or 8320 and OC it, with a 260x. For those games, it would perform a lot better than the 740 and 270x

Point is, atm all I have is an AMD Athlon X4 740 3.2GHz Quad-Core and an old GT 520 that is slowly dying. Buying a new mobo+cpu would be a hard thing to do. May I request you send me some sort of link to where you got the info about said cpu issues?

Haven't looked into it in a few months, so I don't have the links, but I can tell you from personal experience that I got a huge boost when going from an old dual core to an i3, and then another boost i3 to i7. CPU power is very important to planetside, and even decent rigs can be crushed in some intense fire fights, but a cheap mini-atx mobo and a cheap i5 would probably be worlds better than the AMD Athlon. If necessary, I would just save up extra money if I were you, so you can get something a lot better than what you have now. Also, what is the rest of your rig like? Because if that is your CPU+GPU, it may be time for a new rig.

This is a pretty new rig, I don't get much of an income so I try to get what I can.

AMD Athlon X4 740 3.2GHz Quad-Core Processor
MSI A55M-E33 Micro ATX FM2+ Motherboard
(Got these 2 for my birthday ;3)
Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
(Better than stock cooler.)
Western Digital Caviar Green 1TB 3.5" 5400RPM Internal Hard Drive
(Got it from an old home server.)
The power supply is branded by "Tagan", supposedly 900W But I will swap it if it doesn't work with a new Gfx card.
The case is from a old media-pc as far as I can tell. Nothing fancy but quite big.

There isn't much you can do CPU wise with an FM2+ board really, the best you're looking at is a 760k, which isn't a huge improvement if I'm honest. Also, that mobo is a bit low quality, so overclocking with your CPU is going to be limited. The PSU may be fine, although I would be wary of it. That CPU cooler is decent though, and the hard drive, while not the best quality, should be fine. What sort of RAM do you have?

Overall, I think it would probably be best if you saved up and got a new build, maybe reusing the hard drive, CPU cooler, and MAYBE the PSU (I will look into seeing how good it really is). If you have 8gb 1600mhz ram, you could reuse that too.

I have Crucial Ballistix Elite 8GB (1 x 8GB) DDR3-1866 Memory right now, I got it for free and its pretty good :p.

I don't think saving up for a new rig is really much of an option. Maybe an upgrade to a AMD FX-6300 3.5GHz 6-Core Processor + Gigabyte GA-78LMT-USB3 Micro ATX AM3+? As far as I can tell uprading to an i5 would be atleast twice that much.

An FX 6300 would probably be reasonably better. It's single threaded performance boost over the 740 isn't huge, but it overclocks well, and its multithreaded performance is insanely higher. However, that MOBO can only support upto 1333mhz ram, so your 1866 would be scaled way down. The MSI 760GMA-P34(FX) seems like it would be better for your needs, and is only $5 more. You can get an FX 6300 and MSI 760GMA-P34(FX) for slightly under $160. How much money would this leave you with?

As stated before, The 740 will only limit me in cpu intensive games. Im sure I can still play games a good few games better on a 270X with only a 740? Anyways, Im probably going to buy the 270x anyways and then save up for a FX 6300 (or higher) and a nice small mobo that can support the rest of my parts? When I say other games, I mean games like Hawken and Minimum? This might also support Minecraft with decent shaders. Oh and I use http://uk.pcpartpicker.com to find the best parts for the best prices.

Pretty much everyone who has been on this site for more than 2 minutes uses PC Partpicker lol. And while the 740 won't hold you back in games that aren't that CPU intensive, nowadays, every game is pretty CPU intensive, and that CPU will hold you back quite a bit. Also, that isn't even AMD's latest line of CPUs, and their latest line of CPUs is already dead (IE any new CPUs they release won't work with any current MOBOs). That FM2 line is even older, and so is even more obsolete. Get the 270x if you want, but it will be held back greatly by the 740. Also, when you do upgrade your CPU and MOBO, I would get a Z97 board (H97 if you're not overclocking) because that board is compatible with Intel's current CPU line and their new line (when it comes out) so if you get an H97 and i5 4440, you can later upgrade to the new i5 or even i7 if you want.

Why are you so insistent on me switching to Intel? I don't need or even want the latest cpus. What exactly would be wrong with a FX 6300?

Nothing is wrong with the 6300, it is just a cpu on a dead socket, and it is beaten by the i5, so my advice will always be, if possible, go with what is better and can be upgraded rather than what is worse and can be replaced.

Also, the intel method means you can upgrade if you change your mind, the AMD method means you have to replace your MOBO to get a new CPU when the 6300 inevitably becomes how the 740 is now.

Lets do a count of what you say I should pay to have an upgrade-able system.

1. Intel Core i5-4440 3.1GHz Quad-Core Processor: £130.74
2. MSI H97M-E35 Micro ATX LGA1150 Motherboard: £55.16

for a total of £185.9 + Shipping. Now this would be good but considering to upgrade in the future, buying the cheapest mobo will not be a good investment. So lets instead go with this one: MSI Z97-GAMING 5 ATX LGA1150 Motherboard for £99.56 so now we have an upgradeable cpu, reliable mobo, and all for the low low price of £230.3. I could buy a FX6300 and a cheapish mobo and then another similar set of those in 2 years time. (assuming pounds don't loose much of their value and pc components cost about the same.) Please do prove my reasoning wrong here.
