i7 2600k vs i5 2500k worth the $100? - Page 6

post #51 of 72
The 2500k is better bang for your buck.

This is the most sought after CPU on the market today. for a 100 or so bucks I say go with the caddilac .....

more comfortable ride and on those close calls you will have the power to get out of the way
That's all fluff. Actual gaming performance doesn't differ much at all.

Think of it as investing in the future! I mean AMD and Intel have 8 core CPUs in the works... it's just a matter of time before programmers really start tapping into that power.

I guess by that time there will be better on the market, but, I prefer not to upgrade my cpu/mobo every year, so looking ahead is important.

by that time, i will probably not have this cpu

Hmm... well... on the bright side, it will resell for a little bit more when you upgrade. And in the meantime you can put a beating on the bench charts

The upside it brings in some games combined with multitasking far outweights a little fps slip from a game or 2 from 2 years ago that doesn't support it fully.
What you've seen is a higher clocked i7-2600k with higher turbo get beat several times by a lower clocked i5-2500k with lower turbo.


Look at the i5-750 vs i7-920 - equal clocks, but the i5 is always faster than the i7 in the game benchmarks. HT hurts or does nothing - I've yet to play a game that required 4+ cores.

As an GPU upgrade you should definitely get a AMD 69501GB/2GB version.

I strongly disagree. HT only helps if the software coding sucks and leaves idle pipelines. Software should improve as time goes on, not get worse. HT will actually hurt performance if a program is very efficient. You can find several benchmarks that show this.

Partially true. It has a lot to do with the size of the data your working with. Video encoding benefits from HT because encoding software usually deals with several gigabytes worth of data. Since it doesn't fit into CPU cache the pipeline stalls quite a bit since it needs to wait for data to come back from main RAM. HT can hurt when you're running a multithreaded app that can fit most of its dataset into CPU cache, where cache misses are rare.

You shouldn't upgrade for at least 2 years. I say go with the i5 2500k best performance you'll get for $220 and like others said it overclocks like a dream.

When its faster its because the hyper threading gets in the way, but its unnoticeable and very small.
This happens in a few primitive games...so who cares.
Its all about clock speed anyways...not to worried there.

The pros of hyper threading in multi threaded apps/games and overall multitasking far outweigh the cons.
I can easily turn off HT and outpace or match an i5, but I wanted superior multitasking, so I bought the superior CPU.

GTA4 is choppy/unplayable with anything less then 4 cores.
Just ask my 720 X3. :

Both the Hyperthreading aware OS & the processor's logical partitioning units, are prepared to extract the most parallelization as possible, from the running application. It happens that, the majority of apps (games included) are single-threaded. Meaning old. End result: there's a latency penalty when using Hyperthreading with single-threaded software, although a small one (about 3 to 5%).

The very usefulness of Hyperthreading, for now, is simultaneous multitasking, where at least two processes are running in parallel, with a significant advantage over non-Hyperthreading implemented processors.
Toms showed it helping in several titles.

Gaming performance depends on the game itself. Some DX9 games perform much better on HT and dual-core systems than same generation OpenGL based ones. But in the end, all you have to do is enable/disable it and benchmark to see for yourself. Every game uses a different engine, so you can't really speak in general.
Really soon, most games will be multi-threaded, VGA drivers are constantly improving as far as multithreading is concerned, so HT Pentiums and dual-core CPU's might benefit from that.
An i5 would struggle much more then my i7 playing GTA4 while multitasking.
This is a rare case, an i5 overall is just as good for gaming as an i7.

That being said, I like to do 11 things at once , while gaming
Could an i5 do that? Maybe, but as fast as an i7? Nope.

Windows7 was optimized specifically for HT.
