AMD 8 core, or Intel i5

Hi All,
I am upgrading my machine specifically for gaming. I have the age old question of whether to buy AMD or Intel. Budget is not a problem but i still want value for money. i.e. I don't want to buy something that I will not get a benefit from. I want this machine to be useable for gaming for 5 years.

I saw the thread below on tom's hardware. See below and advise?


"Here's the thing. On this site you will get mostly conjecture and opinion instead of fact and sometimes when you do get the facts, they are presented in a dishonest manner trying to slant you in one direction or the other. I simply speak from my own experience (been building PCs for literally 25 years). Now, I am a gamer, in fact I am a HARD-CORE gamer. Gaming is the main raison-d'etre for me having a PC to begin with. I love running modern games completely maxed-out. Now, if you look at my specs (bottom right of this post), you'll see that my processing components (CPU and GPU) are COMPLETELY made of AMD hardware. The reasons are as follows:

1.) The Intel i5 is a faster gaming CPU, but the difference between the i5-3570 and the FX-6300/8350 is so slight that I can't tell the difference.
2.) The Intel i5 is a faster gaming CPU but only RIGHT NOW. As games (and other programs) become more and more threaded, my FX-8350's performance will INCREASE over time while the i5 will remain more or less where it is. That means that my FX-8350 will be useable and relevant for longer than the current i5 because of this. Remember that the FX series architecture is still relatively new and can only get better with more advanced program designs that can actually use all of it.
3.) The FX-6300 has almost identical gameplay numbers as the FX-8350. I only bought the 8350 because I got an "I can't say no to this" deal on it. The FX-6300 is literally half the price of the i5 and again, runs games more or less the same.
4.) The money I saved with the FX-8350 made it possible for me to get my twin Radeon HD 7970s. No game (except maybe Arma III) is even capable of making these cards break a sweat at max settings. I would have had to get weaker GPUs if I had chosen the i5.
5.) The AMD-based motherboards tend to have more features on them than Intel-based boards but are still less expensive. Now, before people start screaming about 4-channel RAM, just remember how the X58 platform with its 3-channel RAM worked out. It didn't. Before people start screaming about PCI-Express v3.0, remember that the Intel boards that have PCIe 3.0 only run multi-card in x8/x8 mode. Since PCIe 3.0 is SUPPOSEDLY twice as fast as PCIe 2.0, it means that since my 990FX chipset does PCIe 2.0 x16/x16, the speed will be the same.
6.) Remember that both the Xbox ONE and Playstation 4 use 8 AMD cores with AMD Radeon graphics. Console ports will most likely perform better on a similar design. Since most PC games are console ports, this will be a very relevant concern.

Since I wanted to have my cake and eat it too, I chose AMD because I wanted maximum performance for my dollar but still wanted maximum performance. I definitely made the right choice because given the same choice again, I would take the same route and not even think twice about it. Remember that even though Intel looks better on benchmarks, human limitations don't allow us to notice those differences. So much the better, it means we don't have to pay top dollar to get a top-shelf gaming experience from our PCs."
 
Prepare for people to argue :)

One of the normal points brought up is what the cost of the different parts means. If getting the i5 is fine for you then it does perform slightly better in quite a number of games, especially ones where you need performance in just a couple of threads. If getting the i5 means you have to buy a cheaper GPU to still be within your total budget then you may end up with a slower computer overall.

What your uses are and what your overall budget is are very important - if you're going for a £4k monster machine then saving a bit on the CPU won't really change what else you can get, but if your total budget is £400 then it is a much bigger deal. If your favourite game is World of Tanks or Starcraft then Intel hold a larger edge, if it's multiplayer battlefield 4 then not so much & a better GPU will serve you better.

The other difference some will talk about is the features of the chipset - PCI-E gen 3 etc. For most people these don't really matter, PCI-E 2 x16 is plenty fast still, but again it varies - if you're going to have 4 titan x's then your GPU bandwidth needs are going to be much higher than if you're looking at a single 750Ti.

We'd need more info to know what the right answer would be for you :)
 
Firstly can i ask, What GPU your going to be using ? Also how ventilated is your case or are you using a full water loop ?

At the end of the day it's personal preference when it comes to picking.
AMD = Cheaper
Intel = Expensive

Both AMD and Intel offer value to performance.

If i was in your shoes, i'd go with the i5 4690k as it's a pretty bad ass CPU.
Although for the same price you can pick up the AMD 9590 which again packs a punch.

I use both amd and intel in my machines, although i tend to game more on my intel builds as i feel more performance.

Good post by David Bisset. Would just add it depends on the games, screen resolution, and choice of GPUs. Also budget. Share these and maybe we can be more concrete.

Despite evidently being a couple of years old the points made in that Tom's post still largely hold true. Some games are less CPU dependant, and cutting from the GPU budget for a more expensive CPU is usually a bad idea.

P.S. predicting the next 5 years is very hard, especially with DX12 coming this year, but CPUs have aged a lot better than GPUs. The fastest single card 5 years ago was a GTX 480, which have pretty much all been replaced, but plenty of i5-2500Ks from the same time are still going strong.
 
Since right now (as you point out) the i5's are faster, go with the i5 unless you are looking to save money. Don't buy on what it might do in the future, buy for what is proven now. If you buy anything CPU intensive get the i5 (i.e. Planetside 2 runs much better on Intel chips)

In a few years you will be buying a new setup anyway to stay current.

As a side note, I would be going with the 'K' version of an i5 so you can overclock it.

With regards to a general "gaming CPU" I'd suggest that there are more scenarios under which an i5 can deliver 100% of its performance...

8 threads; the AMD is in its element, while the i5 has to allocate two threads per core. Intel cores are however faster*, and it is always more than half-as-fast in this scenario, and in some cases still comes out in front.

4-7 threads; some of the AMD cores idle. The i5 will pass the extra threads around its cores to try to share the load. You may still wish for more cores, but at least you get 100% performance.

1-3 threads; some cores idle either way, but you have stronger single-thread performance from Intel.

...whether any of this matters depends, as others have said, on the sort of games you play, and the GPU you pair the processor with :)


* Disclaimer; as far as I know. If anyone wants to find some benchmarks showing a single-threaded program running faster on AMD than Intel, I'd be curious to see it!
 
I've been running a fx 8350 for a couple of years until fairly recently and it served me very well. It fit in my budget and allowed me to spend more on graphics, which affects gaming performance a lot more than the cpu.

If I was in the same position now though, I'd probably go used intel. New I5/I7 K is very expensive but a 2500K/3570k is about £100-120.

3930k + a decent bard for me was only ~£300 which I think is great price/performance and should last a very long time.

What I don't miss about the fx is trying to keep the vrms cool when overclocking. You need a high end board to do it properly, otherwise they'll hold you back quite a bit.
 
What are you upgrading from ?
What are your current specs.

The main point is to buy what you can afford and as long as you're happy with it, to hell with everything else.
If you feel a need to read up afterwards on something you will always find some negatives and positives - no matter what CPU you choose.
I honestly don't know how folk find the time to game anymore as most folk seem to be constantly fettling stuff to get an extra few fps, which is fine if that's what floats your boat.
 
It amuses me how the quoted post in the OP warns away from people fanboying and having biased arguments, then goes on a one-sided tirade about how good AMD are.

Think of it this way: i5 = great performance, all of the time. 8320E = amazing performance sometimes, bad performance sometimes.

In my opinion the 8320E is the only AMD processor worth buying, since the higher variants are just overclocked versions anyway. Note that you will need a carefully selected motherboard for AMD, since things like the VRMs actually matter on that platform for overclocking and system stability.

Overclocking on Intel's side is mostly limited by the chips themselves, so it's just luck of the draw.

I think Intel is the better buy, if you can afford it. (Disclaimer: I own a 3770k, so take that as you like)

"

They're not actually very similar to AM3+ or FM2 cpus though as they don't have a cmt (modular) design and don't share resources between cores. This is the approach they'll be going ahead with in the future with the Zen cpu/apus.
 
What exactly are theses extra features AMD motherboards have that Intel don't?
From my experience even cheap Z97 boards have more features.
Go with Intel if you can afford too, if not then you have your answer.
 
Between the two, the i5.

However overall I would also advise against buying an FX-8, AM3+ is a dead socket (no more CPUs coming), if you must go AM3+ get an FX-6 as the are cheaper and will deliver the same if not better performance in 99% of games.

For many, that IS the game. Think of it as an optimisation challenge :) I imagine everyone on these forums either went through that phase, or is in it still - though for me it kind of died with a 2500K and a loss of appetite for FPS games in general.
 
Core i5 is just better. However, if you're a gamer then the GPU is almost always more important so if your budget won't let you get a decent GPU and a Core i5, then AMD is an option to avoid downgrading your GPU.
 
AMD fx is only really an option if you have a limited budget and/or do other non-gaming task, but as others have said, if you do choose this route, then the 8320e is the recommended buy. You should be able to clock it to reasonable levels (4.4+) with a reasonable board (Asus 990 evo or similar). You will need to factor in a good cooler though.

However, since your main use is gaming with no budget limitations (with a VFM clause), then the I5 (K variety for OCing) is the only real choice IMO.

I would suggest going for one of the cheaper I5 bundles available as they will suit your needs just fine and I'm sure you will be happy with the purchase.
 
Hi gents, some well constructed feedback. It is clear i5 has more support from you guys.

Answers to you questions as follows:
MY CURRENT BUILD
AMD Phenom II x6 1045T
ASROCK M3A770DE motherboard
12GB 1333MHz RAM
MSI TWINFROZRII HD7850 GPU
CORSAIR 750W 80+ Certified PSU

MY ASPIRED BUDGET
CPU/MB = <£350 Intel or AMD
GPU = <£400 to £450 was thinking an NVIDIA GTX980 but open to feedback on AMD cards
RAM will be carryover as it is 1600MHz down clocked as the AMD CPU crashes @ 1600MHz due to memory controller being overclocked.

I do not intend to overclock but maydo in the future.

THE GAMES I LIKE PLAYING
FPS killing floor 2, Battlefied 2, COD, Evolve
MMORPG such as Guild Wars, Elder Scrolls, Star Wars in the future.

This could have saved us a lot of time as from a gaming POV AMD don't yet make a CPU that it's worth you upgrading too from a Phenom X6, the eight core ones have bragging rights due to the extra cores but that's about it, and the FX-6 CPU's are actually an inferior to Phenom because they are not true hex cores.

The i5 is definitely your best bet for an upgrade, however if your X6 isn't overclocked you may want to consider getting a decent heatsink (if you dont have one) as an overclocked X6 is still quite a good CPU (it may be a bottleneck to a GTX980, however it may not be enough of a bottleneck to warrant buying a new MB/CPU if you get my drift).
