ATI Radeon HD 5670 Pictured, Detailed, and Tested

AMD's lower-mainstream DirectX 11 compliant graphics card slated for Q1-2010, the ATI Radeon HD 5670 has been pictured and detailed, sourced from a [H]ardOCP HardForum community member. The HD 5600 series is based on a 40 nm GPU codenamed "Redwood". From the specifications the GPU-Z screenshot shows, it has a 50% downscaled SIMD engine, with 400 stream processors, while it retains the 128-bit wide GDDR5 memory interface, with 16 ROPs. Assuming the clock speeds shown in the screenshot to be the reference speeds, they are 775 MHz for the core, and 1000 MHz for the 1 GB of memory (resulting in 64 GB/s of memory bandwidth).

An engineering-sample of the card has also been pictured, revealing a red-colored PCB breaking away from the black PCB scheme of the rest of the HD 5000 series. The card draws all its power from the PCI-Express slot. The GPU cooler consists of a simple heatsink with radially-projecting metal fins, in which is nested a fan. Output connectivity includes DVI, HDMI, and D-Sub, though the leads behind the D-Sub connector shows that offering a DisplayPort in its place might be possible.
The user also put the card through two tests, in a performance comparison with the Radeon HD 4670 512 MB, the card this one replaces. The test-bed comprised of a Intel Core i5 750 @ 2.66 GHz, Gigabyte P55M-UD2, and 4 GB of OCZ DDR3-1333 memory. The first test was Street Fighter 4 1600 x 1200, no AA, 16x AF. The HD 5670 scored 10,473 points, with average frame-rate of 95.35 fps. The HD 4670 on the other hand, scored 8,559 points with average frame-rate of 65.35 fps. Next was Unigine Heaven Demo v1.0 DirectX 10 (SM 4.0) 1024 x 768, windowed. With the CPU running at 2.53 GHz (according to the screenshot), the HD 5670 scored 859 points with 34.1 fps frame-rate, while the HD 4670 with the CPU running at 2.66 GHz scored 699 points with 27.8 fps.

As far as I know the HD 5850 peaks out @150W and usualy load at around 110W:p
Ths card I will say around 40W and peaks out around 60ish maybe.
I didn't know exact numbers but I was close enough.

The thing is hotter a card gets, the more inefficient it is.
So it ia always important to look at the peak power draw so that the PSU won't over load.
Especially when you are talking about 300W PSUs. :twitch:

My 4670 and my 9800GT green edition works just fine with my 250 PSU.

But besides the point, 300PSU for the non powerconnector 5670 should be just fine. I only plan to have 2 dvd drivers, one hard drive, thats it.
