Looks like even SweClockers are sometimes wrong.

Few days ago they claimed that the bundle was postponed, however the retailers have a different opinion. In fact the bundle is already available for preoder, starting from 7299 SEK.

AMD Radeon R9 290X Specifications

One of the stores even posted the final specifications (source):

GPU Codename – Hawaii
GPU Process – 28nm
Stream Processors – 2816
TMUs – 176
ROPs – 44
Base Clock – 800 MHz
Turbo Clock – 1000 MHz
VRAM – 4GB GDDR5
Memory Bus – 512-Bit
Memory Clock – 1250 MHz (5GHz Effective)
Memory Bandwidth – 320 GBps
Power Configuration – 8+6 Pin
PCB VRM – 5+1+1
Die Size – 424mm2
Transistors – 6 billion
3D Technology – DirectX 11.2, OpenGL 4.3 and Mantle
Audio Technology – AMD TrueAudio

This is pretty much what we’ve expected. The R9 290X will feature Hawaii XT GPU with 2816 Stream Processors. In addition to that we have 176 TMUs and 44 ROPs. The base clock is 800 MHz and Turbo clock is 1000 MHz. You should probably get used to turbo clock, since this is how AMD is calling their boost clock from now on– the mechanism of this technology is very similar NVIDIA’s temperature driver GPU Boost, but for details you will have to wait at least two weeks when proper reviews will be published.

AMD R9 290X is using 4GB GDDR5 memory across 512-bit interface with bandwidth of 320GB/s. The memory clock is 1250 MHz (5 GHz effective). The same site even posted a die size of the Hawaii GPU — which is almost exactly what we’ve calculated — 424 mm2.

According to the information posted by Inet, there are at least four different manufactures selling their cards — ASUS, MSI, Gigabyte and Sapphire. The other store, which posted the specs, claims that the cards will be in stock starting from October 11th, few days prior to the embargo date.

2816个SP 1000MHz VS 2688SP 876MHz , 和7970GH 对GTX680的结局差不多，只不过SP没有多很多，但频率又高很多了。
