AMD announced three new graphics cards with RDNA 2 architecture today. They all have faster memory than 18 Gbps and higher GPU hours, but the disadvantage is higher power consumption and higher MSRP. Earlier today we published our in-depth review of the AMD Radeon RX 6950 XT, a very thick Sapphire Nitro + Pure model. While you wait for our RX 6750 XT and RX 6650 XT models to go through the labs and under the watchful eyes of our graphics editor, it’s worth taking a look at the changes to the specs provided by the rest of the family.

Productivity, power and price (reference card)

According to AMD’s own tests, the AMD Radeon RX 6950 XT provides 4.6% faster 4K games in ten modern games than the RX 6900 XT. To achieve this, it uses 11.7% more power and costs 10% more money using AMD’s own data.

A similar analysis of the RX 6750 XT in 1440p games suggests that it has an 11.7% increase in performance compared to its older brother, while consuming up to 8.7% more power at a price of 14.6% higher.

Finally, the RX 6650 XT, tested by AMD in 1080p games, is 4.8% faster than the RX 6600 XT, but will consume up to 12.5% ​​more power and will sell for 5.3% markup. Not exactly ringing approval and mostly factory overclocked card, except with faster memory.

If we can rely on AMD’s internal data and MSRP data, the value proposition is generally quite weak. Each new card has an advertised increase in performance that is exceeded by the increase in MSRP. In addition, they will all be more energy-hungry, and as next-generation GPUs wait later this year, we’re not convinced that upgrading to a new card makes much sense right now.
