AMD Radeon HD 6670, HD 6570 and HD 6450 GPUs Go Official, OEM-Only

While the graphics powerhouses in the Radeon HD series typically get all the bells and whistles when launched, things are a bit more mainstream as far as mid-range versions are concerned, and this is exactly the treatment AMD's new Radeon HD 6670, HD 6570 and HD 6450 seem to be getting.

So, as TechPowerUp reports, AMD has just introduced the three GPUs we've mentioned above, that, for the time being, will only be available for OEMs, which means that it will be some time before end-customers will be able to get their hands on them.

The Radeon HD 6670 and HD 6570 are both built on the Turks GPU platform, featuring 480 VLIW5 stream processors and a 128-bit wide GDDR5 memory controller that supports GDDR3 on lower SKUs.

The full-height, single-slot heatsink HD 6670 is clocked at 800 MHz core, and comes with either 1GB or 512MB of GDDR5 memory clocked at 1000 MHz, while also attaining a total bandwidth of around 64 GB/s.

The low-profile HD 6570, on the other hand, is only clocked at 650 MHz, and offers two different memory clock speed specifications, depending on the type of memory manufacturers have chosen.

So, if they decide to go with up to 2GB of GDDR3 memory, the frequency is set at 900 Mhz, but if they opt for up to 1GB of GDDR5, the clock is set at 1000 Mhz.

Last, but certainly not least, comes the HD 6450, which is based on the Caicos platform and is the absolute entry-level offering in AMD's lineup, packing 160 VLIW5 stream processors, a 64-bit memory controller that supports GDDR5 (800 - 900 MHz) and GDDR3 (533 - 800 MHz), while GPU clock speeds vary between 625 MHz and 750 MHz.

Last, but not least, we'll have to mention that this GPU has been designed for low-profile, and silent (passively-cooled) cards.

No details regarding the pricing (even for OEMs) have been provided just yet, so it's quite likely that we'll have to wait a bit longer in order to find out such important pieces of information.
