delivers news that AMD's upcoming Radeon R9 270X graphics card is based a faster version of the Radeon HD 7870 "Tahiti LE". The new model possibly has higher clockspeeds and more stream processors. Pricing is $199.
"Tahiti LE" is a major variation of "Tahiti," which features not just lower numbers of stream processors and TMUs, but also a narrower 256-bit wide GDDR5 memory interface. The die is mated with a more compact BGA package that has lower pin count, thanks to the narrower memory interface, and probably fewer power/ancillary connections. Sources reveal the R9 270X to be "a crippled HD 7950," which could indicate a stream processor count of 1792, higher than the 1536 of Radeon HD 7870 "Tahiti LE." The TMU count could be proportionately higher due to the way they're structured on the GPU; at 112, compared to 96 on "Tahiti LE."
