Both chips run at 3.33GHz but the 661 has a 900MHz GPU while the 660 runs at 733MHz.

Representing Clarkdale I have a Core i5-661 and 660. I paired it with a 6-core 1100T to keep the CPU from impacting things. AMD’s 890GX is still the cream of the crop for AMD integrated for at least a few more months. On the integrated side we have a few representatives. Both of these cards were paired with a Core i5-2500K to remove any potential CPU bottlenecks. This is more memory bandwidth and much more compute than the HD Graphics 3000 can offer.īased on what we saw in our preview I’d expect performance similar to the Radeon HD 5450 and significantly lower than the Radeon HD 5570. The core clock remains at 650MHz and the DDR3 memory interface has an 1800MHz data rate. Priced at a whopping $70, this GPU comes with 400 SPs and a 128-bit memory bus. The Radeon HD 5570 is a more formidable opponent. The 5450 will set you back $45 at Newegg and is passively cooled. That’s more compute power than the Intel HD Graphics 3000 but less memory bandwidth than a Sandy Bridge if you assume the CPU cores aren’t consuming more than half of the available memory bandwidth. The SPs run at 650MHz and the DDR3 memory interface has a 1600MHz data rate. The 5450 is a DX11 part with 80 SPs and a 64-bit memory bus. I dusted off two low-end graphics cards for this comparison: a Radeon HD 5450 and a Radeon HD 5570.
