Intel Core i5-3470 Ivy Bridge Processor and HD 2500 Graphics Review

HD 4000 Processor Graphics and Quick Sync Performance

Obviously with the jump from HD 4000 to HD 2500 graphics on the Core i5-3470 desktop processor, we were curious to see how the new integrated graphics performs in real-world gaming. To test it, we pit the Core i7-3770K against the Core i5-3470 and also included a discrete graphics solution to mix things up. I chose to test these CPUs against AMD's Radeon HD 5570/6570 card that you can currently find on the market for $50-60.

I had some requests to include another discrete level card like the GTX 560 Ti in these graphs, but in truth, it skewed the results so heavily that it made seeing the performance differences between the HD 4000 and HD 2500 graphics pretty difficult.

Ouch, first indications are that that the HD 2500 is half the speed of the HD 4000 and even behind the HD 3000 from Intel's Sandy Bridge processors.

A similar story here in our Left 4 Dead 2 testing with the HD 2500 about half the speed of the HD 4000 found in the Core i7-3770K.

The same is seen here in Deus Ex: Human Revolution...

...and in DiRT 3.

Intel is actually being pretty honest with its marketing names on their processor graphic solutions. The HD 2500 found on the lower cost Ivy Bridge processors is indeed slower than the HD 3000 found in last generations Sandy Bridge CPUs. It is also producing about half the performance of the HD 4000 found in the higher end IVB options which always leads to the same question: why put the higher end graphics on a processor that will likely NOT use but instead add in a discrete solution? Intel obviously wants you to have to pay for that higher end graphics if you are going to utilize it, so keeping a price premium between the Core i5 and the Core i7 lineup is doing that nicely – though it really hurts the idea of the integrated graphics being a "value" for the consumer.

Quick Sync Performance

For our basic Quick Sync testing we used the latest version of Cyberlink's MediaShow Espresso to convert a 1.8GB 720p H.264 video file down to a more reasonable size for an iPod.

The results are pretty damn impressive:

The fixed function hardware used for the QuickSync operation is the same across the HD 2500 and HD 4000 graphics solutions so the Core i5-3470 performs just as well as the Core i7-3770K.

The most compelling use of the HD4000 graphics is in the mid to low end segment. OEM's may disagree but I think that Intel forgets that they can compete with AMD and Nvidia on the low end discreet GPU segment if they just put their best foot forward.

We are still waiting for their sub $200 chips. Now if they could just marry the great x86 performance with HD4000 (or better...).

If I had to guess, they won't pair their sub-$200 chips with the better HD400 graphics :(

That is a pretty good guess.

The decision to not do so makes me want to smash 300mm wafers over CEO's heads.

I don't understand, is it just me or do most review sites always give awards now days. To me the simple fact that the 2600K is still avalible for about the same price would make this a no-award product.

Quote : "Still, the Core i5-3470 would make a solid low cost processor for users looking to build a reasonable cost machine for some mainstream gaming and general enthusiast computing."

If I'm buying a cpu for mainstream gaming and general enthusiast computing I'm not buying a processor with a locked multiplier.

Love the site, keep it up!

Comparison to Ivy i5 3570k in benchmarks, wrap-up?

Why does Intel still sell HD2500 in their chips? Tired of Intel hashing up older GPU architecture just to satisfy price points.

Does this chip matter that much when the i5-3550 already exists? Very small differences between the two chips, and only a $5 difference on Newegg. (A promo right now actually makes the 3550 even cheaper).

I was excited when I first heard about this chip... but now I think it's just another unnecessary SKU.

Is the intel core i3 cpu& intel hd graphic suitable for cfd code in fortran?
what about fluent 6.3?

Eh man yo check it yo! I got this Intel stuff from Intel since I am a partner yo! And I can sale it at half price. I got i7's for $500 and Intel i5's for $400 and i3's for $350 yo! That's cheaper than you ever get it at old egg yo!
