AMD RX 7700 XT and RX 7800 XT Graphics Card Review
AMD has finally released cards in the mid-range, targeting high refresh-rate gaming at 1440p with its new RX 7700 XT and RX 7800 XT graphics cards. The new cards start to round out the full product stack from AMD in the RDNA 3 line of GPUs, providing an alternative at the $500 price range from last-gen and competitor offerings.
AMD’s latest GPUs squarely target the mid-range, providing potential consumers with an upgrade path if the previous RX 7900 XT and RX 7900 XTX were out of reach since their launch last December. Using the same chiplet design for its GPU as the rest of the RDNA 3 line, the RX 7700 XT and RX 7800 XT both target 1440p gamers.
We covered the chiplet design in more detail in our review of the RX 7900 XT and XTX, which you can check out here. The chiplet design splits the GPUs into two regions: the 5nm Graphics Compute Die in the center with the 6nm Memory Cache Die flanking the GCD on each side. This design is only possible thanks to the incredible engineering by AMD’s team to create the high-speed 5.3 TB/s interconnect, bringing some of the design language from its incredibly popular Ryzen and EPYC CPUs.
The RX 7700 XT and RX 7800 XT share the same amount of transistors (28.1 billion), though the 7700 XT looks slightly pared-down than the 7800 XT. The 7700 XT has fewer compute units (54 versus the RX 7800 XT’s 60 CUs), fewer of AMD’s 2nd generation ray accelerators (also 54 versus the RX 7800 XT’s 60), as well as fewer stream processors (3456 versus 3840). Both sport 2nd generation AMD Infinity Cache, with the RX 7700 XT boasting 48MB compared to the RX 7800 XT’s 64MB of Ifinity Cache. Both have large pools of VRAM, with the RX 7700 XT having 12GB of GDDR6 memory while the RX 7800 XT has 16GB of
