Reviews of the new AMD 790GX chipset hit the web earlier today. This chipset features several enhancements like Advanced Clock Calibration (ACC) and the new Radeon HD 3300 IGP. You can check out reviews at:
How about a short recap. The 790GX Northbridge is actually a 780G that has its stock core clock speed increased from 500MHz to 700MHz along with a graphics core name change from Radeon HD 3200 to HD 3300. Sideport Memory, now called Performance Cache, is a “requested” feature on the boards that improves IG performance about 5% on average, sometimes less, sometimes more. The SB750 Southbridge is basically a SB700 with RAID 5 operation and the new ACC interface. Mix the two parts, stir, and you have the highest performing integrated graphics solution on the market today.
