AMD Outs Radeon HD 6670, HD 6570, HD 6450 for OEMs

AMD released the entire entry-mid portion of the Radeon HD 6000 series overnight, for OEMs only. The cards won't be available to consumers (retail) as yet, but does give away specifications of two new GPUs that AMD is carving these SKUs out of, Turks and Caicos. Built on the 40 nm process, Turks packs 480 VLIW5 stream processors, is DirectX 11 compliant, and sports a 128-bit wide GDDR5 memory controller that supports GDDR3 on lower SKUs. Radeon HD 6670 and HD 6570 are based on Turks. Both have all 480 stream processors enabled, differ in memory type/amount and clock speeds. The HD 6670 carries clock speeds of 800 MHz core, 1000 MHz (4.00 GHz GDDR5 effective) memory, and is available with memory amounts of 512 MB or 1 GB. The 128-bit wide memory interface churns out bandwidth of 64 GB/s.

The HD 6570 is also based on Turks, but features clock speeds of 650 MHz core, and two different memory clock speed specifications based on the memory type opted for by the manufacturers. If a manufacturer chooses GDDR3, it's clocked at 900 MHz (1.80 GHz GDDR3 effective), with a memory bandwidth of 28.8 GB/s. If it's GDDR5, it's clocked at 1000 MHz (4.00 GHz effective), 64 GB/s bandwidth. Up to 2 GB of memory can be opted for GDDR3 designs, while up to 1 GB can be opted for GDDR5-based ones. While the HD 6670 reference board uses a full-height design with a single-slot fan-heatsink, HD 6570 is designed for low-profile cards, best suited for HTPCs or SFF PCs.

Lastly, there's the HD 6450, which is based on the Caicos silicon. This is AMD's entry-level GPU, which is geared to be an IGP replacement or for users who just need a GPU that does everything an IGP does, faster. Caicos is an improvement over previous-generation Cedar. It features 160 VLIW5 stream processors, twice that of Cedar. It features a leaner 64-bit memory controller that supports GDDR5 and DDR3. Partners are free to set GPU clock speeds in the range of 625 MHz to 750 MHz, while its memory can be clocked at 533 to 800 MHz for DDR3, or 800 to 900 MHz for GDDR5. It is designed for cards that are both low-profile, and silent (passively-cooled). There's no information on retail release, but we can't imagine them to be too far away.

How are these renamed? I remember the old ones had 400 shaders, and these have 480.

Only 6700 series is pure rebrand (5700 series + hdmi 1.4).

HD6670 sounds way more powerful then my old good HD3850, without 6-pins molex...

I think it is around 4770 performance. if not, it's rather close.

benchmarks will tell the whole story, but if it could match 4770 it would be good!

the 6450 w/ 160 shaders looks tempting for HTPC and occasional light gaming :D

said this when we got previews, but I like the 6450 heatsink XD

it's always refreshing to see the lower midrange/low end cards come out and have comparable or better specs than the high end of a few years back, this is where we can see some great advances in perf/watt and general power consumption.

so the only cards in the 6XXX series with the new architecture are the 69XX cards. . . . . . . . . . sad

and the only cards in the gtx5xx series with the new architecture are the .....oh wait

i'd say both companies were limited by the delay of 28nm

no i didn't mean it like that, its just that they have such a good architecture with the Terascale 3 why not make more cards similar to that, it should've been possible but it looks like when they taped out the 6970 thats all they planned on to use it.

So the Brazos GPU is based off the 80 shader Cedar GPU. I believe the Llano GPU is based off this Turks 480 shader GPU, unless they opted for something older from the HD 56xx series.

480 shader based on HD6800 series shader design = HD4770 like performance = win win!!!

So its possible some of these cards will be release as retail?

So if AMD outed these cards does that mean they were in the closet?

Hmmm, the HD 6570 looks like almost exact same as my HD 5570, except now there might be GDDR5 variants, instead of just GDDR3. Same core and ram speeds. Only difference is 480sp vs 400sp on the 5570.

come on people get rid of the vga! i don't care if this is low end stuff the only way for people to move on is by forcing them! to be honest i think dvi needs go too.

Why? Don't make a stupid statement unless you are going to give reasons...

^ that's the only rebrand in the whole series, and you do know that those will never make it to retail? more than likely the OEM's wanted AMD to rebrand so they could market them.

the gpus this article is talking about has nothing to do with the 67xx, only the 66xx series and lower.

all of these gpus will eventually make it into retail and increased their shader counts by 80 each.

VGA's time has certainly come. The cable used makes a difference in visual quality, especially at 1280x1024 and above, so it's not as suitable for today's higher resolution monitors as other solutions. Someone correct me if I'm wrong, but removing support should also make video cards slightly cheaper as they wouldn't need a RAMDAC? I also see benefit (multi-monitor, broadness of application) in reducing the connectors available today from four to three.

All i know is that VGA can handle HD & is not limited by resolution afik but HDMI & DVI have faster bandwidth & can handle sound at the same time

Hmm the 6450 may be a good upgrade for my HTPC's 3450.

Going from 40 stream processors to 160 and from GDDR2 to GDDR5 (both 64bit bus width) while still being half height and passive with clock speed increases sounds like a good upgrade although i look forward to reviews, mainly to see the temps as my HTPC gets pretty toasty as it is.
