AMD has the Radeon R9 290 was announced. The video card has just as the flagship, the R9 290X, a ‘Hawaii’gpu, but one with a lower number of Compute Units and lower clock speed than the 290X. The R9 290 needs to go to compete with Nvidia’s GTX 780.
AMD’s R9 290 has 40 Compute Units, which equates to a total of 2560 streamprocessors. These are clocked at up to 947MHz, 53MHz less than the 290X. The geheugenbusbreedte with 512bit equal to that of the 290X and the memory speed of 5GHz is the same, for a total bandwidth of 320GB/s.
The Radeon R9 290 should contend with Nvidia’s GTX 780, which since June 2013 is available. That map was recently substantially reduced in price and is now for around 440 euros in the Pricewatch. From benchmarks that Tweakers with the map has rotated, and that in a review later on Tuesday come online, it appears that the GTX 780 and R9 290 are indeed well-matched. AMD’s msrp for the R9 290 is 350 euro.
