EDIT: some people pointed out that comparing clock-for-clock thermals and not similar performance thermals was not a great comparison. So I've included a similar performance thermal comparison immediately following the existing clock-for-clock comparison

I've seen too much false information in regards to AMD vs. Intel flying around here lately, so let's see if we can't put to bed some of the myths.

I didn't cherry-pick any of the following benchmarks to prove my point, and although performance differs between the two from benchmark to benchmark, I selected benchmarks indicative of the gaming landscape as it stands right now.



MYTH: AMD runs hotter than Intel
FACT: On a per clock basis, AMD actually runs cooler than Intel BUT it does draw more power, which I guess it where the myth came from.
EVIDENCE: Intel Core i7 4770k clocked at 4.8GHz runs at 93°C load (high-end air cooling)

AMD FX-8320 clocked at 4.8GHz runs at 55°C load (low-end Corsair H60 water cooling)

Similar Performance Thermal Comparison

At stock 3.7GHz the 4770k (lots of people here agree that to get stock 4770k performance out of an FX-8xxx you'd have to overclock the FX in the neighborhood of 4.8GHz--so this is essentially comparing similar performance instead of clock speed) runs at 78°C max load on an NZXT Havik 140:
QK7tE70.jpg


which is directly comparable to the H60 that I use on my 8320 according to this:
tLeQC49.jpg


So my 8320 at 4.8GHz more or less equals the performance of the 4770k at stock, and it runs at 55°C max load versus the 4770k's 78°C max load (both were tested with Linx-AVX) with directly comparable cooling solutions--again Intel runs hotter, on a clock-for-clock basis and a similar performance basis.




MYTH: AMD is dramatically slower than Intel in game performance
FACT: AMD frequently falls behind Intel in gaming benchmarks that is true, but never so far that a game becomes unplayable on AMD--even in the worst cases, AMD maintains more-than-playable frame rates.
EVIDENCE: Intel Core i7 4770k runs Civ5 @ 1440p Max Settings (Radeon 7970) at 85fps
55339.png


AMD FX-8350 runs Civ5 @ 1440p Max Settings (Radeon 7970) at 71fps
55339.png


A difference of 14fps and both are well north of the desired 60fps threshold.

Intel Core i7 4770k runs Crysis 2 (DX11) at 1920x1200 Max Settings at 97fps
fkN9nR0.png


AMD FX-8350 runs Crysis 2 (DX11) at 1920x1200 Max settings at 85fps
fkN9nR0.png


A difference of 12fps and, again, both are well north of 60fps.

There are some rare instances, such as Skyrim which is heavily dependant upon single-core performance, where the performance delta between the two are much wider, but even in those instances AMD puts out more-than-playable numbers:
Intel Core i7 3770k runs Skyrim @ 1080p Ultra Settings (Radeon 7970) at 107fps
image016.png


AMD FX-8350 runs Skyrim @ 1080- Ultra Settings (Radeon 7970) at 70fps
image016.png


A big difference of 37fps, but both are able to maintain above 60fps.



MYTH: AMD will bottleneck a multi-GPU setup
FACT: AMD FX and Intel i5/i7 have more than enough power to push frames to a multi-GPU configuration
EVIDENCE: Intel i7 3770k with SLI GTX 680s puts out 162fps in Battlefield 3 Ultra 1080p
image009.png


AMD FX-8350 with SLI GTX 680s puts out 150fps in Battlefield 3 Ultra 1080p
image009.png


A difference of 12fps and both are way more than you'd need for a smooth, responsive gameplay experience.

Intel i7 3770k with Crossfire 7970s puts out 77fps in Battlefield 3 Ultra 1080p
image008.png


AMD FX-8350 with Crossfire 7970s puts out 75fps in Battlefield 3 Ultra 1080p
image008.png


A difference of a mere 2fps, both above 60fps.



Those are the three biggest myths that have been bugging me and there are more, but I feel better having cleared these up.

I'll leave you with some basic, no-nonsense facts about AMD and Intel performance:
FACT: Intel has better single-threaded/single-core performance than AMD
FACT: AMD has just as good, and sometimes better, multi-threaded/multi-core performance as Intel
FACT: AMD FX draws more power than Intel i5/i7
FACT: The bottom line is that both AMD FX and Intel i5/i7 are fantastic CPUs that are more than capable for even the most demanding gaming scenarios--Intel is the all-around speed king, but AMD is no slouch and is frequently right there with Intel or not very far behind.

So enough with the Intel vs. AMD infighting, they aren't that different after all and neither will let you down when it comes to gaming :)
 
An anti-trolling anti-fanboy post? Well worded and well referenced? Awesome! +1 for you, sir. :)

I'm going to add this as a favorite.


I'll add a rule of thumb that I keep posting in response to this kind of question. It is a very simple answer:

Q: Which is better/faster?
A: Depends greatly on your apps/games and how many cores they can use.

Yeah, I was tired of seeing people post things like "Intel is SOOO much faster/cooler/sexier than shitty AMD!" and the like, so I threw together an admittedly hurried comparison to show that's simply not the case.

I own an FX, but I love Intel too! I don't know why we have to pick one and fight to the death about it :/

Because we all need something to quarrel about. intel vs amd is just like the first few ios vs android debates or the playstation (2,3,4) vs xbox (1, 360, one) debates or countless other unnecessary, arbitrary debates
 
It's just fanboys living vicariously through their purchases. And personally, I LOATHE fanboys and BS hype.

I see this as a responsibility. Some people spend large sums of money based on recommendations and debates on this subject. We need to give them accurate and complete info based on up-to-date sample data and reference scenarios.

I recently saw a YouTube fanboy post that the i3 was superior to the FX 8350 in Arma, Crysis, Far Cry, Metro, and everything else he could think of...claiming the AMD lost 100 frames to the intel. And I bet some people bought it and wasted their money thinking an i3 would be some miraculous gamer dream CPU to solve their budget quandry. >.<

Ouch. The i3 does have better single-core performance than FX, but not by much--and once multi-core performance comes into question then it's no contest.

Still, an i3 is a solid choice if you're playing older games, or play a shit ton of Minecraft and Skyrim and the like.

By all means I'm no fanboy of anything. But we all have to agree that AMD is still trailing Intel, but at the rate Intel is going (haswell is great and I own one but for the price and the very minimal performance boost) AMD will take a lead.

Competition drives excellence. (Intel vs. AMD: Nvidia vs AMD: Apple Vs. Android) :)

The piledriver is a great architecture (There are some points in it I do disagree with), but overall a strong architecture, which can be capable of doing great work. (A better branch predictor would be prefered)

For the general consumer for gaming:
The CPU shouldn't be your top priority, as it is true that the performance difference isn't significant.

For workstation it can all depend on with ISA the appplication support, as it can be more critical than simply more or stronger cores.

Something that have bother me for a while is that people thinking having 20+ tabs open, playing a game, listen to music and talking on skype is multithreading.
It is not, that is due to how windows schedules its processes.
Windows scheduler will most likely try stack all application on a single core.
A program needs to be specifically programmed to utilize more cores.
 
Windows scheduler will most likely try stack all application on a single core.

No it won't; it will schedule a thread to a processor core that is currently unused, or bump the lowest priority thread currently running. Thread's jump around ALL THE TIME, and this actually hurts performance when a thread jumps to a core that uses a different physical cache on the CPU.
 
Nice post s4in7. :jap: Hope this will be seen by a fair few. I still maintain though, as those benchmarks show, intel is ahead even if it is slightly in some scenarios. ;)

Just thought I'd chuck in a few benches too. These are a few of the top selling games on Steam atm, ones that I could find benches for. Again I maintain that intel are ahead, but the gap is very close.

I was almost set on grabbing a Xeon 1230v3 and a H/B motherboard, or a 4670k and accompanying Z motherboard. However, I still have an 8320 lying around, wondering if I should get a mobo for it and pop it in my system... Hmm...

No it wont. Windows will try stack most process on a single core, so it wouldn't have to keep the other cores active(save battery, not fucking up with the cache).
True multi-threaded experience wont be noticed on windows, because of how it schedules its process.
EDIT: The only situation where Windows does things intelligently is when you start loading several applications and they're all intensive; at that point the distribution starts getting intelligent.

Thanks Jook, that means a lot coming from you!

And you're right--Intel is ahead of AMD in most scenarios, but my whole point was that AMD is still well above a viable option, even if it's not as fast as the fastest.

I love my 8320 personally, paired with a decent motherboard it can really sing! I know clockspeed isn't everything, but it's damn nice to see 4.8GHz on the screen lol

Thank you so much. I too am tierd of seen "Intel crushes AMD in games", with no facts or facts that show Intel winning by just a couple points or Intel being really good in one area but falling short in another. Can we say on average Intel is better than AMD, maybe but you have to back it up with facts. In the end it is up to the buyer if they want to pay the extra money for the performance Intel provides.

When I see a 2.66ghz I7 matching a 4.0ghz FX in Metro on a Titan I definitely steer towards the Intel camp for a gaming CPU. You look at frame rates just that they're above 60 fps and not the fact that the Intel is around 15% faster for similar Ghz. That has the effect that the Intel will last you longer as the cpu is pushed harder in the future. OK the Intel will cost you more but then it does perform better. You should get the best you can afford at the time that suits your requirement whether that be Intel or AMD. I've had both in the past and have no preference I just want the best for my purpose/price and in recent years it's been Intel for me. If AMD made that killer CPU that would be in my next build.

I am now not looking for 60fps. I look to 120 fps to go with a 120hz monitor or one with Gsync. These seriously reduce input lag and give a much smoother gaming experience which I remember from my CRT days. It took me ages to adapt to a flat panel screen and I now realize why. The only reason to look for 60 fps+ is most panel screens don't go above 60hz and it reduces tearing effects. Any extra fps at 60hz on those is wasted frames as they won't get displayed anyway. When you move into the 120hz world it's a revelation especially in fps games.

FACT: On a per clock basis, AMD actually runs cooler than Intel BUT it does draw more power, which I guess it where the myth came from.

But would it better to compare the temperature with the same performance level instead of clock speed?

Major_trouble, you're one of the very few super high-end gamers that look to game with 120hz or 144hz monitors or even UHD monitors--the fact remains that a LARGE majority of gamers are running beige boxes (check the Steam hardware survey if you don't believe me) where 60fps is the line between playability and not playable.

I have a 4.8GHz 8320, 16gb G.skill 1866MHz RAM, and dual Radeon 270Xs and I game on a 60hz monitor, as do most gamers.

If you're in the super high-end gaming market, then chances are you're not looking at AMD anyways--this comparison is for the majority of gamers, and not the elite few.

I would not consider myself super high-end and certainly not elite. Maybe high-end though. There are much more powerful machines than mine. Admittedly I have a i7 3770 at stock and have splashed out on a 780ti (I know, I know the 800s are here soon). Some people are sticking in SLI Titans etc and I am not in that realm by any stretch. You've even stuck CF 270X in your rig are you super high-end?

I recycle my components by upgrading my computer and move the parts down to other family machines. I've only recently upgraded a sons GTX8800 last year so I get my moneys worth out of my components.

Yes the 60 fps is the difference on a 60hz monitor but as gaming is being more and more dumbed down to console levels and more reasonably priced PC components get higher fps more people can reap the benefits of high fps especially if they get a high Hz monitor in the future. I don't have one yet myself either but I got the 780ti in preparation and am saving the pennies for when the ROG Swift PG278Q launches if it's in my price range.

This notion that consoles are dumbing down PCs is another bothersome one--the fact remains that the average gamer can't reliably discern a difference between 60hz and 120hz so how is adhering to the 60fps Golden Standard of Playability "dumbing down"?

I'm glad you are enjoying your rig, and I do consider my rig high-end, but I just can't justify the price or purported benefits of a faster monitor--my 50" 1080p 60hz plasma provides a perfectly smooth, fluid, and cinematic gaming experience so I'm not interested in the faster monitors and I'm not the only one.

Let's not get into a discussion about 60hz vs. 120hz or whatever, this threads purpose is to show that both Intel and AMD are more than adequate at delivering fluid and enjoyable 60fps+ gaming experiences.

Very good post I must say. Intel are all round performers, but AMD is no slouch, that is what I try to tell every Intel vs AMD warrior. AMDs are very good for what they are for the price they come. Although I have an i3-2120 under my rig's hood, and I very much love it, but somewhere at the back of my mind I also wish I had a 6300 someday. Although my dual core did not come cheap for having only 2 cores, but it makes me feel better that each core is being utilized efficiently (hyper threading) and that each cycle is strong and I don't need to overclock (I know I can't anyways lol). I even read somewhere that if you disable HT, then the single thread performance would increase further? Can anyone help here?
