Moving on to power consumption, perhaps because of AMD’s more aggressive specifications for their lower-tier card this time around, power consumption is not dropping at all.
Compared to the 290X, practice will be favoring the 290 by far. Paper will of course be the key word here, as in the case of 290 more so than any other card we’ve looked at in recent history theory and practice will not line up. As such despite the wider price difference this time around, performance on paper is going to be notably closer.

290 retains a larger percentage of 290X’s shader and ROP performance, never mind the fact that the full 320GB/sec of memory bandwidth is being retained. At their top boost bins this gives 290 95% the clockspeed of 290X, and 91% of the shader hardware, giving 290 100% of 290X’s memory performance, 95% of 290X’s ROP and geometry performance, and 86% of 290X’s shading/texturing performance.Ĭompared to AMD’s last generation offerings, the 290 is going to be closer to 290X than 7950 was to 7970. However AMD has not cut the amount of memory, the memory clockspeed, the memory bus width, or the number of ROPs, leaving those at 5GHz for the memory clockspeed, 512-bits for the memory bus width, and all 64 ROPs for the back-end hardware.Īs a result the differences between the 290 and 290X are on paper limited entirely to the clockspeed differences and the reduced number of CUs.
AMD has cut the number of CUs from 44 to 40 – disabling 1 CU per SE – while adjusting down the base GPU clockspeed and boost GPU clockspeed to from 727MHz and 1000MHz to 662MHz and 947MHz respectively. We’ll have a full rundown in the following pages, but in a nutshell AMD has thrown caution into the wind in the name of maximizing performance.ĭiving right into the hardware specifications, Radeon R9 290 is a bit more powerful than usual for a lower-tier part. The merits of 290X were already hotly debated in some gaming circles for its noise relative to its performance and competition, and unfortunately 290 is going to be significantly worse in that respect. Now officially AMD has not announced the Radeon R9 290 in advance, but with listings for it having already gone up on the same day as the 290X, it’s something that everyone has been expecting.Īs always we’ll offer a full breakdown of performance and other attributes in the following pages, but before we even begin with that we want to point out that the 290 is going to be one of AMD’s most controversial and/or hotly debated launches in at least a couple of years. Making the usual tradeoffs for a lower-tier part, AMD is cutting down on both the number of functional units and the clockspeeds, the typical methods for die harvesting, in exchange for a lower price. Launching today will be the Radeon R9 290, the obligatory lower-tier part for AMD’s new flagship lineup. With the successful launch of the 290X behind them, and the equally successful launch of their new flagship GPU Hawaii, AMD is ready to make their next move. Consequently with GTX 780’s price cut being NVIDIA’s counter to 290X, 290 has gone from just being a lower tier Hawaii card to also being AMD’s counter-counter, and in the process has become a somewhat different card than what it was going to be just one week ago.īut before we get ahead of ourselves, let’s start at the beginning.
Meanwhile AMD has also made some changes, and although 290X is unaffected for the moment, 290 was affected before it even launched, receiving an arguably significant specification adjustment. NVIDIA for their part cut the price of the GTX 780 and GTX 770 to $500 and $330 respectively, repositioning the cards and giving them their first official price cuts since their spring launches. The 290X not only reasserted AMD’s right to fight for the video card performance crown, but in doing so it has triggered an avalanche of pricing and positioning changes that have affected both NVIDIA and AMD. With the launch of AMD’s Radeon R9 290X less than 2 weeks ago, the video card marketplace has become very active very quickly.
