AMD's Radeon RX 6000 Graphics Cards Refreshed in Last Hurrah for RDNA 2

AMD’s Radeon RX 6000 Graphics Cards Refreshed in Last Hurrah for RDNA 2

Posted on


AMD has announced three new RDNA 2 architecture graphics cards today. They all feature faster 18Gbps memory and higher GPU clocks, but a drawback is higher power consumption and higher MSRPs. Earlier today we published our thorough AMD Radeon RX 6950 XT review, a very fat Sapphire Nitro+ Pure model. While you wait for our RX 6750 XT and RX 6650 XT samples to pass through the labs and under the beady eyes of our graphics editor, it’s worth taking a look at the changes in specs delivered by the rest of the family.

Performance, Power and Price (Reference Card)

According to AMD’s own tests, the AMD Radeon RX 6950 XT delivers 4.6% faster 4K gaming across ten modern games when compared with the RX 6900 XT. To achieve this feat it soaks up 11.7% more power and costs 10% more cash, using AMD’s own figures.

A similar analysis of the RX 6750 XT at 1440p gaming suggests it pulls off an 11.7% performance uplift compared to its older brother, while eating up to 8.7% more power with a price that’s 14.6% higher.

Lastly, the RX 6650 XT, tested by AMD in 1080p gaming, is 4.8% faster than the RX 6600 XT but will consume up to 12.5% more power and sell for a 5.3% price premium. Not exactly a ringing endorsement and basically a factory overclocked card, except with faster memory.

If we can rely on AMD’s internal figures and the given MSRPs, the value proposition is rather weak overall. Every new card has a touted performance boost that is outweighed by the MSRP increase. Moreover, they will all be more power hungry, and with next-generation GPUs waiting in the wings for later this year, we’re not convinced upgrading to a new card right now makes much sense.
