Why i5 2500k over i7 960

post #1 of 44
Thread Starter 
I understand it's the craze, but I don't understand. How is an i5 better? I am trying to build a new computer for around a thousand dollars. My friend suggests: Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor BX80623I52500K
ASRock P67 EXTREME4 (B3) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
MSI N560GTX-M2D1GD5 GeForce GTX 560 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
....etc

I really want

Intel Core i7-950 Bloomfield 3.06GHz LGA 1366 130W Quad-Core Processor BX80601950

ASUS Sabertooth X58 LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Intel Core i7-950 Bloomfield 3.06GHz LGA 1366 130W Quad-Core Processor BX80601950.

I understand the lower wattage and the die...sorta. But really why and how is a 1 gen newer lower level product blow a last gen higher end out the water flat out? can post rest of those two builds to. IDK...

Because the 2500k is a faster cpu, both at stock and overclocked settings.

Really it is as simple as that

Mostly because 1366 is a dead chip design they are going to be using the 1155 design for the next release of processors so it is easier to upgrade. Also it has better performance, mostly because how good it overclocks.

Here is a quick comparison

the 965 is same clock speed as the 960 so dont worry about that.

The 960 wins in 25% of benchmarks, those being benchmarks that benefit from hyperthreading. Though the 2500k overclocks better(usually) so it could probably beat the 960 in more after they are both overclocked.

the 2500k is much better in single and dual threaded apps, which will likely be the biggest difference

Faster architecture, lower TDP / runs cooler, overclocks way better.

The lga1366 dated back to few years ago, its not a slow chip, but just can't compete with the newer ones.

The newer chips overclock further, and beats it clock for clock.

If you're buying a new system, then Sandy Bridge is really the way to go outside the budget arena. The chip is just *SO* much faster than any previous chip, and it clocks like a demon.
The only area where 1366 still wins out over SB is the tri/quad-sli and x-fire equivalents, as SB just doesn't have the PCI-E lanes to cope well. Socket 2011 is due out at some point this year (I think) which is the replacement for 1366 and will boast SB type chips on a platform of similar power to the current i7-1366 platform. If you can wait, that (or possibly bulldozer) will be the way to go, really.

I'd go with the i5-2500k. Like a few people already stated, it's faster clock for clock, will overclock higher, stay cooler and is on a platform that will continue to receive upgrades.

Dx. Aww. So being a dinosaur = fail T_T. I wanted to build the rig I thunked up for a project in PC OS and Assembly lol.... Well after undergoing a budget cut =P.

Also at the start, even intel was stating the SB chips weren't supposed to be for high perforrmance/gaming situations. The first gen i7 chips also use triple channel memory which seems a very useful thing?
other thoughts: using for gaming PC for now...CAD machine later.
