German website Schottenland.de is currently listing a 40nm AMD Radeon HD 4750, offering details on the RV740 GPU and other specifics. This could mean we'll be seeing a refresh soon.
Looks like it won't be long before desktop Radeon GPUs with 40nm processing will hit the market, and apparently it starts with the Radeon HD 4750. While AMD has yet to make any kind of announcement in regards to an actual street date, German website Schottenland.de already has the card listed (link), sporting a huge red fan, two DVI jacks and a burgundy circuit board. For the moment, the website has only one online retail outlet listed, Neobuy, currently selling the Radeon HD 4750 for $175 USD (€129.90).
According to the listing, the ATI Radeon HD 4750 uses the RV740 GPU, clocking in at 650 MHz with 640 stream processors and using shader version 4.1. On the memory side, the card sports 512 MB of GDDR5 clocking in at 3200 MHz, and utilizes a 128-memory interface. In addition, the card shows that it features not only two DVI outputs, but an S-video output jack. The specs also indicate that it does support CrossFire and CrossFireX configurations, and is HDCP ready. The card consumes 78 watts of juice and connects via a PCI-E 2.0 slot, and will possibly work without an external power connector.
By comparison, the card's specs are (basically) on the same level the ATI Radeon HD 4830 card that offers a core clock of 575 MHz, 640 stream processing units, a 256-bit memory interface and 512 MB of GDDR3. While the specs may look slightly better, the 4750 could perform just a tad slower than the 4830 due to the memory bandwidth. On the price front, the Radeon HD 4830 sells around $100, so it's possible that the 4750 will utilize the same price point.
If all goes well, the Radeon HD 4750 should arrive on North American shores in Q2 2009.
