AMD May Unveil 40nm Radeon HD 4750 Soon
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.
I'm wondering what the OC potential is for this card.
i'm very tempted to buy 2 of these for cf to replace my 4850 because even 2 of them should be fine on my 500w psu whereas a 4850x2 probably will not. and the performance will be close too, approx 1.8 gflops (900x2) for the cf'ed 4750's vs. 2 gflops for a 4850x2
Everything in that testing puts it's just shy of the 4850 by about 5 - 8%, not to mention they claim that AMD said the price will be in the budget range of 90 - 100 euros.
I just have a feeling they stole it directly from there TBH, the price tag seems even more wrong.
Hopefully it'll cost around the same the HD4830 costs now...
AMD invested into GDDR5 2 years ago. nVidia hasn't so they have to design a card to utilize it first and that takes more then a year.
from 45nm to 40nm isn't as good of an improvement as from 65nm to 50nm, or 50nm to 45 nm.
it's about a 10% more efficient,or, for the same power can be upto 10% faster.
Only a pitty they didn't focus on the 4660 and the 4850!
4660 due to it's already low powerconsumption,and the 4850 because that's what most people want to buy! (not the previous technology!
The AMD CPU is 45nm, the GPU isn't. And As far as it's known, the 4890 (to come in April) is still made on a 55nm fab.
And the preliminary testing gives it JUST shy off the 4850, for alot cheaper, so yeh... it would help to read more Websites about this stuff next time
The 4890 is supposed to be not too far from a GTX285.
The 5XXX series AFAIK is planned for the 40nm build.
