Radeon HD 5700 Series Specs Surface
The beans are spilled on the final specifications of AMD's "Juniper" mid-range GPU architecture, and the two SKUs based on it, namely the ATI Radeon HD 5770 and Radeon HD 5750. Leaked alleged company slides on XtremeSystems Forums, reveal exactly how Juniper is a 50% downsizing of Cypress' machinery, in having half of nearly all its vital-statistics, if you may. Juniper features 10 SIMD engines physically, amounting to 800 stream processors. It holds 40 texture memory units (TMUs), and 16 raster operation units (ROPs). With a 128-bit memory interface churning out up to 76.8 GB/s of memory bandwidth by utilizing 4.8 GT/s GDDR5 memory chips, the fact that Juniper is half of what Cypress stands for specs-wise, becomes clear.
In the next two slides are pictured and detailed the two SKUs based on the GPU. The ATI Radeon HD 5770 is the top-end implementation, which makes use of all the components present on the GPU. With a core clock-speed of 850 MHz, and memory speed of 1200 MHz, the GPU churns out a shader compute power of 1.36 TFLOPs. The idle and max board powers are rated by AMD at 18W and 108W, respectively. It becomes clear that AMD is eying the US $150 price point with this part. The Radeon HD 5750 on the other hand, has one SIMD engine disabled, and eds up with 720 available stream processors. It comes with 1 GB or 512 MB of GDDR5 memory, and clock speeds of 700 MHz core, and 1150 MHz memory (4.6 GT/s). With these, the Radeon HD 5750 manages a shader compute power figure of 1.008 TFLOPs. The rated board power consumption figures have also come down on this one, with 16W idle, and 86W max. This one targets the $109 (512 MB) and $129 (1 GB) price points. Both accelerators are DirectX 11 compliant, and support ATI Eyefinity technology supporting up to three 2560 x 1600 pixel display heads. According to the slides, they should be unveiled this Tuesday the 13th.

Minus the 128-bit memory bus that is.
I can't afford 3 30 inch monitors, and I like the one I have now, but the option of running 2 sounds awsome, can you guys let me kno0w if this is a stupid idea.
It seems to me like 5750 & 5770 are supposed to have power of the 4850 & 4870, but with the benefits of Eyefinity, DX11, lower power use, lower price, smaller PCB, +++, wow... the list is just going on and on.:rockout:
I'd hate having the devide in the middle and would prefer a single or triple set-up.It would make sense for them to make the previous generation power(-level) cards now be the number 2's in their line-up, with all the new features to make them preferable over the previous gen, so yeah, I'm thinking these are the HD4800s replacements. And pretty excellent ones at that.:)
the laptop versions should be incredible too.
The specs are in numbers a 4890 on 40 NM with DX11 and 128Bit GDDR5 bus.
And the price seems fair too :)
Seems like HD 5670 Will be:
- 400 SP
- 512 / 128 bit / GGDR3 or 64 bit (GDDR 5 ?)
- Very low power (less than 50w full / 9w idle ?)
- Low profile format ?
- Under $70.00
Well at least this is what I hope it to be... :laugh:
400 sp for sure
very low power.
Which is 6W idle and 19w max.
