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.

as it is low profile and lower power than a 4830 it might make alot of sense to run this in crossfire.
Anyway, this looks very good for the market, I figured it would perform similar to an HD4830 due to the similar specs, I'm guessing it only really outperformed it due to the higher clock speeds. If they do managed to get this out at the under $100 price point, it should hopefully force price cuts on some of the nVidia GPUs in the range, which would be very nice.
Also, the PRO will not need a 6-pin power connector.
Good news for us no matter if we want this card or not.
It's intresting how this war turned up to be , if you remember Nvidia wanted a perf. war with huge GPU's that perform very fast but , AMD/Ati forced them to their own kind of war with fast and cheap cards , they knew they couldn't beat them at speed so they made cheaper to produce card and kill them with low prices , smart people there at AMD.
Now Nvidia is playing their game cutting production costs , bad thing for the competition to force you in their kind of war and AMD doesn't want to play Nvidia's games no matter what happens ( they don't want to adopt physx ).
It will be intresting where this goes and where will see Nvidia and AMD/ATI in 2-3 years from now , let's see if one of them fails eventually considering AMD is poor this days and Nvidia is at war with everybody.
