Benchmarks

System setup

Below is a partial set of Intel Core i5-2500K and i5-4670K benchmarks from our CPU benchmark database. The former processor was tested on ASUS P8P67 motherboard with 2 GB dual-channel Corsair TR3X3G1600C9 DDR3 memory, and MSI R6670 1GB GDDR5 (ATI Radeon). The latter processor was tested on Intel DH87RL motherboard, that had 2 GB dual-channel Corsair TR3X3G1600C9 DDR3 memory, and MSI R6670 1GB GDDR5 (ATI Radeon) graphics. For different system configurations please see tests of Core i5-2500K and i5-4670K CPUs in our benchmark database.

All tests were performed at default frequency and voltage, using manufacturer's stock fan/heatsink. None of the components were overclocked. Motherboard BIOS options were left at default settings.

The results of all benchmarks are broken into four categories: multi-threaded, single-threaded, memory intensive and graphics / gaming.


Core i5-2500K vs i5-4670K single-threaded benchmarks

Single-threaded benchmarks run on a single CPU core, and do not depend on such features as the number of cores, or Hyper-Threading technology. Additionally, they do not utilize on-chip caches, dedicated to other cores.

Core i5-2500K vs i5-4670K graphics benchmarks

Graphics benchmarks depend on the type of integrated or discrete graphics adapter, and to less extent on the processor performance. Because these benchmarks are synthetic, they may not truly represent gaming performance. However, they still can be used to estimate whether one processor will perform faster or slower than another CPU in games and other 3D tasks.

Both OC@4.4GHz easily

Posted by: Daniel

Very easy to do and almost 100%
With 4.5GHz and up, chance of success decrease.

negatively surprised

So you are saying that after 2 generations i5-4670K is only
13% to 17% faster than i5-2500K?. Doesn't sound very promosing for the future.

Why bother testing these without overclocking?

Posted by: Michael

Why buy either of these CPUs if you don't plan to overclock? So, why test them without overclocking? Pointless.

I've run my 2500K @ 4.8GHz using a Noctua NH-D14 air cooler for 40 hours a week for the last couple of years with no stability issues.

From what I read, only 30% of 4670K CPUs can even reach 4.6GHz, 20% 4.7GHz, 10% 4.8GHz. So, you could probably only count on 4.5GHz.

A 2500K @ 4.8GHz would compete reasonably well with a 4670K @ 4.5GHz.

The real point of comparing these two CPUs is to help existing 2500K owners figure out if an upgrade is worthwhile. The answer is no.

I agree with Michael from above

When i looked at this review, side-by-side, at first look i said "wow, should've waited for Haswell because it's the last generation in 4 cores family", and started a little to regret buying a sandy.

After reading Michael's post, i totally agree with him. This article is useless. You're just comparing base products which are unlocked, rather than comparing them full boosted (BECAUSE THAT's WHY THEY'RE UNLOCKED). I was reading it just to see if it's worth it to upgrade. But thanks to Michael, i know it doesn't!

Cheers,
L.

Indeed like they say above, no need to upgrade, unless when by OC there is a big difference.

Posted by: Leon

Maybe the performance is not much better but efficiency became fantastic.

I guess when you overclock a i5-2500k to 4,8 you will have idle power of nearly 100W. Or tell me what do you have when I'm wrong.
