AMD May Unveil 40nm Radeon HD 4750 Soon

by - source: Tom's Hardware US

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.

AMD leading in the transistor size race? WAAAHHHhhhtt?? :) Sounds like some good news. I, for one, am tired of hearing about bail-outs and company lay-offs.

I'm wondering what the OC potential is for this card.

Actually due to it's higher core clock speeds initial previews put the 4750 above the level of the 4830 but below the 4850

Wow 40nm already. Nice Job AMD/ATI. I thought that was going to be another 6 months out or more.

So this will show us the difference between GDDR5 (twice as fast) with a 128bit bus (half as wide), and GDDR3 (half as fast effectively) with a 256bit bus (twice as wide)?

just what i was wondering. it's possible it might be constrained due to not having an external power connector. it's good to know that if you can stably push the memory clock to 900, it will have equal memory bandwith as the 4830 and thus will easily outperform it.

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

Also it uses GDDR5 instead of GDDR3. I find the appealing part of this card to be its power requirements which are quite low compared to other cards today.

The preliminary tests done on this very card are done by Guru3D,

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.

Can't wait for this card, it's going to replace my HD4670. :p
Hopefully it'll cost around the same the HD4830 costs now...

Why isn't nVidia using GDDR5 yet?!?

They're talking about calendar year, so Q2 = April 1 - June 30. Hopefully closer to April 1, but lately tech companies have been squeezing it in at the end (I'm looking at you, Nehalem).

Oh well, I'm still happy with my GTS 250.

So should the price of this card be closer to $100 or $175?

Anyone heard anything to the noise levels of this beautiful fan?

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.

Waiting for truly DX 11 VGA that able to run D3D11.

You would've been correct if not for the fact that the current fab sizes of both ATi and nVidia are 55nm.

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 :)

Ah bugger... i meant with the above preliminary testing the 4750 ofcourse (name in fact still is unknown and was guessed to be as such)

The 4890 is supposed to be not too far from a GTX285.

The 5XXX series AFAIK is planned for the 40nm build.

what difference is it going to make?
ati cripples their memory bandwidth with half the memory interface of competing nvidia cards
as long as it gets the right performance, I don't care what type of video ram goes into my video card

kenmasters :
i have a Toshiba sat with a radeon HD card, the only way i can re-install a corrupted driver is to reformat my entire computer and bring it back to stock settings.


You are a complete moron.

I have a Toshiba with a HD2600, I updated the drivers to 9.3 using a modder... and it works fine... Maybe u should try to figure what happened to your pc, instead of making such comentaries...

Also comment above the 2000's series pissed off classic gamers it could do work in 256 color mode meaning sc wasn't playable with those card not sure if it still like that

Now all i need is an after-market cooler to replace the crappy stock cooler ati usually gives that just blows air around and is annoyingly loud not that ati does much better. I like older cards they have VGA coolers i can buy and drivers are usually optimized to a decent point.

I wonder if they should have called it the 4835 to keep the line in numerical order for performance... but who knows, maybe it one of those that will depend on the benchmark run...

Everybody will buy a new PC in 2010 because of:
- 32nm Processors
- 40 nm Graphics card
- Cheap Blue Ray and 1080*1920 display
- Windows 7

wow, technology just keeps getting better and better:)
i wonder how well this new die shrink will overclock...

lets not forget:
dx11
sata 3.0 (6Gbps)
USB 3.0
SSD's on the cheap (maybe)

yup, 2010 will be a good year for the industry
blu-ray isn't a good enuff reason IMO.. but everything else is. efficiency is the future =]

ive been wondering why they didnt make the 4850 and 4830 with GDDR4 instead of the old GDDR3 that nvidia still uses. GDDR4 overclocks a heck of a lot better than GDDR3 IMO. maybe to keep prices down...?
