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.

Here's a quick recap of AMD's updated product stack, spread between the R9 and R7 series. This article can help you understand the new nomenclature. AMD's lineup begins with the Radeon R7 250 and Radeon R7 260X. The two are based on the 28 nm "Curacao" silicon, which is a variation of the "Pitcairn" silicon the previous-generation Radeon HD 7870 was based on. The R7 250 is expected to be priced around US $89, with 1 GB of RAM, and performance rated at over 2,000 points by 3DMark Firestrike benchmark. The R7 260X, features double the memory at 2 GB, higher clock speeds, possibly more number crunching resources, Firestrike score of over 3,700 points, and a pricing that's around $139. This card should turn up the heat against the likes of GeForce GTX 650 Ti Boost.

Moving on, there's the $199 Radeon R9 270X. Based on a chip not much unlike "Tahiti LE," it features 2 GB of memory, and 3DMark Firestrike score of over 5,500 points. Then there's the Radeon R9 280X. This card, priced attractively at $299, is practically a rebrand of the Radeon HD 7970 GHz Edition with. It features 3 GB of RAM, and over 6,800 points on 3DMark Firestrike. Then there are the R9 290 and R9 290X. AMD flew dozens of scribes thousands of miles over to Hawaii, and left them without an official announcement on the specifications of the two. From what AMD told us, the two feature 4 GB of memory, over 5,000 TFLOP/s compute power, and over 300 GB/s memory bandwidth. The cards we mentioned are pictured in that order below.More pictures follow.

TechPowerUp announced the latest update to GPU-Z, the popular graphics hardware information, monitoring and diagnostics utility. Version 0.7.3 brings in a few major changes, keeping in mind plans by AMD and NVIDIA to update their product stacks, a little later this year. We've added preliminary support for Radeon R7 240, R7 250, R7 260X, R9 270, R9 270X, R9 290, and R9 290X. On the NVIDIA front, we've added support for GeForce GT 625, GT 645, GT 755M, GT 745M, GTX 760M, GTX 765M, GTX 770M, Quadro K1100M, and K5100M. Support was also added for AMD Radeon HD 7600G, HD 8250, HD 8330, HD 8470G, HD 8570, HD 8570G, and E6460; FirePro W7000, and W600. GPU-Z 0.7.3 brings improved support for GeForce GTX 780 graphics cards with CHiL CHL8318 voltage controllers, and GeForce cards in general, with NCP4206 controllers.DOWNLOAD: TechPowerUp GPU-Z 0.7.3 | TechPowerUp GPU-Z 0.7.3 ASUS ROG-themed
