i5 2300 vs. i5 2500k vs. non SB i7

post #1 of 24
Thread Starter 
Can someone please tell me how Gaming performance differs between the i5 2300, i5 2500k and a non SB i7? Some help along with some charts will be appreciated. The CPU will be using an HD 5870 and I will game at 1080p.
Thanks in advance

I'm sorry but there wasn't a single piece of information regarding the i5 2300

Yeah, but the 2300 should perform like the i7 leve, a little lessl...i'll look for more.

Short answer is that the SB, in the most ideal gaming conditions, exhibits maybe a 10-15% IPC advantage over Bloomfield/Lynnfields. This is actually pulled from the FrazPC article, which compares a 4Ghz SB to a 4Ghz Bloomfield and Lynnfield.
http://translate.google.com/translat...z.html&act=url

Again, this is specifically gaming. I guess the more important question is how much AA do you usually use at 1080P. If you prefer high IQ, that could swing it back to being GPU-limited, which will make the IPC differences fairly small. The IPC discussion is really academic, since if you combine a much higher OC (let's say 4.7Ghz SB and its 10-15% better IPC), the choice is unquestioned. Unless you're on an existing Bloomfield/Lynnfield setup, you should be buying a SB setup. *This is more of Intel's problem of never price-reducing the older chips.

2500k eats the older i7s and skip the i3. For ~$100 more you get a huge performance gain.

Excellent find and very interesting. Looks like my i7 920 could actually be a bottleneck of sorts. Thanks.

If you already have a first gen /i3/i5/i7 no need to upgrade, unless you really want to. If you are building a new system, go with 1155.

Look at the stock clock speed. There is a 600Mhz deficit with your 920 compared to the 2500k in those benchmarks and they are running medium settings. With both overclocked and a decent GPU you are looking at a few frames in difference at best with an upgrade to a 2500k. If you had an AMD/775 system, it would be completely different.

Eh, if you're gonna refer to some benches, at least find some that give you more data than just averages. Anandtech gives some really shallow benchmarks when it comes to that (it's like reading USA Today for news).

Techreport provides min. and mean data, along with FPS graphs. This really aids in giving more context when you are looking at CPU-scaling.
SC2 and BC2 are tested:
