AMD rolls out HD 6450/6570/6670 for OEMs

Turks and Caicos for OEM
In addition to the recent rebrand of the HD 5770 and the HD 5750 to HD 6750 and HD 6770, AMD has now added three more cards that will be a part of its HD 6700 series OEM offer, the HD 6450, HD 6570 and the HD 6670.

Unlike the previous rebrands, these new cards are based on a completely new 40nm Caicos and Turks chips. The slowest of the bunch is the HD 6450. This one is based on the entry-level AMD Caicos chip and features 160 VLIW5 stream processors, a 64-bit memory interface and works with both GDDR5 and DDR3 memory.

The GPU clock for the HD 6450 will be set between 625MHz and 750MHz while the 512MB to 1GB of memory will end up clocked between 533 and 800MHz for DDR3 and 800 to 900MHz for GDDR5 versions. It is important to note that the Cedar predecessor had half the amount of shaders so the new HD 6450 is a nice addition to the lineup.

The HD 6570 and the HD 6670 are both based on AMD's Turks chip that features 480 stream processors and 512MB or 1GB of GDDR5 memory paired up with a 128-bit memory interface. The faster, HD 6670 works at 800MHz for the GPU and 1000MHz (4.0Gbps) for the GDDR5 memory. These specs are enough for 768 GFLOPS of single precision compute power.

The HD 6570 will end up clocked at a bit slower 650MHz and will be available with both GDDR5 and the DDR3 memory. The GDDR5 version will end up at the same 1000MHz (4.0Gbps) while the DDR3 version will be clocked at 900MHz (1.8GHz).

The Caicos based HD 6450 ends up with a low-profile, passively cooled PCB that features DVI and HDMI outputs and it is pretty clear that these might be quite an interesting cards for an HTPC system. On the other hand, Turks based HD 6570 also features the low-profile PCB but paired up with a small fan/heatsink cooler. The HD 6670 is left with a full height PCB, single-slot heatsink/fan cooler.

Bear in mind that we are still talking about OEM only cards and there is no info on when will these be available in retail, but we guess that more info should follow up soon and that they could be just around the corner. You can check them all out here.
