AMD expects The Radeon R9 270X to do quite well for the company. Also being priced at $199, it brings along a huge advantage. Sources from some leading online retailer have revealed quite an interesting piece of information, much to the benefit of the company as it reveals the stop keeping unit’s resemblance to the limited edition Radeon HD 7870 “Tahiti LE.
But the resemblance is not doing enough justice to the latest SKU of AMD as the Radeon R9 270X is said to be faster with higher clock speeds and stream processor count. Tahiti LE is a variation of the Tahiti which features lesser number of stream processors and TMUs. It also has a narrower 256-bit wide GDDR5 memory interface. A much more compact version of the BGA package, featuring a lower pin count, has been mated with the die and this could probably be the result of the narrow 256 bit memory interface. Part of this can also be attributed to the fewer power connections. Sources have labeled the Radeon R9 270X as a crippled HD 7950 which could possibly be directing towards a stream processor count of 1792, which is higher than what the Radeon HD 7870 “Tahiti LE” had (1536). The higher TMU count on this can be explained by their placement on the GPU; structured at 112 instead of 96 which was the case with Tahiti LE.
