With a market presence of close to two years and counting, the Radeon HD 7000 series kept AMD afloat in the discrete PC graphics market. The company pretty much sat out 2012, probably focusing its efforts on getting its next-generation console chips right. Come Q4 2013 and a product stack update is long overdue for AMD. The company feels that the silicon it built its HD 7000 on is still fit for due provided they're repositioned in the product stack much in the same way NVIDIA shuffled its with the GeForce GTX 700 series. Much like NVIDIA, AMD is going into its new generation with just one new chip it codenamed "Hawaii" while repositioning "Tahiti" and "Pitcairn" based SKUs one tier lower.

The R9 290 series will succeed the HD 7900 series in the product stack, and the R9 280 series succeeds the HD 7800 series (sub-$300 class) while the R9 270 series succeeds the HD 7700 series (sub-$200 class). Since such an arbitrary product stack repositioning would create unreal price-performance increments at the price points AMD's HD 7000 series products launched, AMD also tweaked pricing a little, so there really is a different and equally valid way of looking at AMD's new product stack by using price points.

The $199 AMD Radeon R9 270X then draws its lineage more from the Radeon HD 7800 series than any other. The R9 270X is, for all intents and purposes, identical to the Radeon HD 7870 GHz Edition which launched at $350, but settled down to around $250, holding on to that price-point quite well, and for quite long. At 1050 MHz, its GPU core clock speed is 5 percent higher, and at 1400 MHz (5.60 GT/s effective), it has a significant 16 percent higher memory clock speed than the HD 7870.

The 28 nm "Pitcairn" silicon on which the Radeon R9 270X is based features 1,280 stream processors based on the Graphics CoreNext micro-architecture, 80 texture memory units (TMUs), 32 raster operations units (ROPs), and a 256-bit wide GDDR5 memory interface holding 2 GB of memory. Interestingly, it doesn't meet the recommended system requirements for "Battlefield 4," the season's most hotly anticipated game for the PC platform. AMD is trying to project the card as an ideal buy for gaming at 1080p display resolution.
