Radeon R9 270X a Faster Radeon HD 7870 "Tahiti LE"
AMD's performance-segment Radeon R9 270X could prove to be a winning sub-$200 product for the company. Sources affiliated with a leading online retailer revealed that the SKU could greatly resemble the limited edition Radeon HD 7870 "Tahiti LE," possibly with higher clock speeds and stream processor count. "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." The clock speeds are still under the wraps. AMD set an SEP price of the Radeon R9 270X at $199.

HD4850 and HD4870 price war repeat telecast again ?
Will this card beat Nvidia's Titan when rendering BF4 over Mantle?
the 270X is pitcairn renamed asic to curacao XT so its either 1280 shaders or a pitcairn xtx 1536
6810 Curacao XT [Radeon R9 270X]
6811 Curacao PRO [Radeon R9 270]
You must have missed the :rolleyes: right after the word 'probably'.
This specification of the R7 270 would make sense if the R9 280X is an insanely high clocked Tahiti (not just a GHz edition). It would give AMD a place to dump all their chips that can't clock very high but don't have many (or any) shader defects.
However: This is what I was thinking, especially if it's a "Pitcarn" replacement. Either way it's shaping up to be absolutely awesome.
edit: I take back my previous statement about this new lineup being more confusing that the current one. At last count, AMD has 10 products on the market. If this new lineup has 8 or 9, that will be an improvement.

Will Mantle be somewhat comparable? We can hope...
