Radeon HD 4750 Previewed, Performs Closer to HD 4850
An unexpected visitor to Guru3D.com's offices was a pre-release sample of a yet to be released 40 nm RV740-based Radeon HD 4750 graphics accelerator. Not bound by any NDAs with AMD, the website went ahead with a little (p)review of the card. The HD 4750 is the RV740XT model, and features GDDR5 memory. The name contradicts an earlier report suggesting HD 4770 to be the shelf-name for the RV740XT, and HD 4750 for the GDDR3-based RV740Pro. It features 640 stream processors, core clock speeds between 650~700 MHz and GDDR5 memory clocked at 800 MHz (3.20 GHz effective), across a 128-bit wide memory bus. The RV740XT comes with a rated shader compute power of 900 GFLOPs, as against 740 GFLOPs the RV770LE-based HD 4830 is rated at, while having similar specifications. It comes with 32 TMUs and 16 ROPs.
The findings of the preview show it to be somewhere between the performance levels of the Radeon HD 4830 and HD 4850. Interestingly, Guru3D omitted GeForce 8800 GT/9800 GT from the comparison, though GeForce 9600 GT was left to face the onslaught from stronger ATI GPUs. The Radeon HD 4750 is expected to be priced below the $100 mark and is expected to outperform most competitive accelerators in its price-range. To read the review, head over to Guru3D here.

I bet you this is the reason they didn't put some gddr5 in GTX280 so they have a better case with rambus and Ati paid to rambus what was need it so they had acces to latest memory types.
this may be a prelude to a 1280SP 32 ROP 40nm card that keeps a 256-bit GDDR5 bus to keep costs low....
they are fighting so they don't end up like nvidia
Ever since the 3xxx series came out, I was always hoping for a 3950, 3970, etc...
Also, still yet, if they have currently won on that front, I would move on to win in another department (IE high end), and whenever nv threatens mid-range, start the battle again. Seems they are beating a dead horse, when there are plenty of other horses to....w/e, you know what I mean.
it looks good for a HTPC, but if it sucks up more then 100 watt, it might be somewhat problematic,
