14 DAY TRIAL // Just a few moments after AMD made official the Radeon HD 6670, HD 6570 and HD 6450 graphics cards, MSI has introduced its new solutions built on these chips, which promise to deliver improved reliability thanks to the Military Grade components used by the company.
The least powerful of the three video cards announced today is the R6450-MD1GD3/LP which is built on top of the AMD Caicos core.
This packs only 160 SPs, 8 texturing units, 16 Z/Stencil ROP units, 4 color ROP units and its GPU comes clocked at 625MHz.
The 1GB of DDR3 memory is connected to the core via a 64-bit wide interface and it operates at 667MHz (1333MHz effective).
The card is actively cooled and uses a low profile PCB, just as its older brother, the MSI R6570-MD1GD3/LP.
This too features 1GB of DDR3 memory, this time clocked at 900MHZ (1800MHz data rate), but is based on the much more powerful Turks core that is also employed in the Radeon HD 6670.
Turks is comprised out of 480 streaming units, 24 texturing units, 8 ROP units, a 128-bit memory bus, and, in the case of the R6570-MD1GD3/LP, its clock speed is set at 650MHz.
Finally, the last graphics card to be announced today by MSI is called the R6670-MD1GD5 and is built on top of the same Turks GPU, but, this time, its clock speed is set at 800MHz, while the 1GB of GDDR5 memory works at 1GHz (4GHz effective).
The R6670-MD1GD5 also features a more advanced cooling solution, that uses a full length aluminum heatsink seconded by two fans, as well as an enhanced power delivery system with “Super Ferrite Chokes.”
All the graphics cards are bundled together with a 3DMark 11 license and with MSI’s proprietary Afterburner hardware monitoring and overclocking software which also features the Predator video capture function.
