i5 4670k vs AMD-8350

Intel always.

I think you know the answer

They are both about the same for gaming

Watch this its a good video

The AMD will require more power and run a little warmer but it is a very good option.

Rely on what I told in other question. This is a question asked any times. An 8320 would be better.

The intel will outperform the AMD in 99.9% of games. The dispairty in performance will depend on the game, many recent titles will perform similarly, others there will be a vast performance difference. You will also gain far more performance from overclocking the intel than overclocking the AMD, due to its higher IPC.

As has been suggested above, the 8320 would be a better option than the 8350. They are the same chip except the 8320 is clocked lower at stock - you can match 8350 speeds with a little multiplier bump.

I'd take a 4570 over an FX though, regardless of the 4670k.

Moreover Logan (TekSyndicate)'s video is full of inaccuracies and has been criticised on many grounds. Love the guy, just not those particular tests.

I know you've already masked the question as solved, but the intel would be the better option. You can get an i5 4570 and a decent motherboard for the cost of an 8320 + 990FX motherboard (990FX is basically necessary for a healthy overclock). Remeber you cannot overclock on all of the AMD motherboards, there are many factors that come into play. Here's a database to give you at least a basic view as to which would be suitable if you go that route: http://www.overclock.net/t/946407/amd-motherboards-vrm-info-database Remember to factor in the cost of a good CPU cooler too.

Right, so I configured a few builds.

Firstly, a Xeon build. Identical performance to an i7 4770.

Slightly over your budget.

Second build. I changed the CPU to an i5 4570.

Thirdly, an AMD build. The i5 4570 is likely to outperform this. Couldn't squeeze an aftermarket CPU cooler into the budget. You could chuck a Hyper 212 EVO in and that could get you to around 4.5GHz. It's likely that the 4570 would still outperform it most of the time.

So there you have it. If you can stretch the extra ~£30 I'd grab the Xeon build in a heartbeat. If not, and gaming is the main concern, the 4570. Then there's always the 8320 if you're interested in a little worse gaming performance, but comes with overclocking capability and the 8 threads can be great for productivity apps such as video editing. The Xeon could take the lead in that department as well though.

AMD will be better in future games, even if in todays games the i5 performs better

Wrong.

Jook Is mostly correct, but I wouldn't say the FX has worse gaming performance--an i5 4670k with SLI GTX 680s puts out 162fps in Battlefield 3 Ultra 1080p whereas an FX-8350 with SLI GTX 680s puts out 150fps in Battlefield 3 Ultra 1080p...a difference of 12 frames per second and both give waaaay more frames than you'd every need.

Yes, Intel is faster, but it's patently false to say the FX has worse gaming performance when it still performs far above and beyond what you require of it.

Also, an AMD build should almost always be cheaper than a comparable Intel build--not sure why Jook's AMD build is the 2nd most expensive.

Both CPUs are great and will provide all the performance you could need in the next few years so either will work perfectly--an Intel edges a small performance lead here and there, but there's also a price premium whereas AMD is right there with it or not far behind at all with lower cost.

Your call!
