58Introduction
ASUS TUF Gaming Radeon RX 7900 GRE OC is the company's most premium custom-design graphics card based on AMD's latest performance segment offering. While we await ASUS's coveted ROG Strix brand to extend to the Radeon RX 7900 and RX 7800 series, the TUF Gaming brand currently represents ASUS's very best, and interestingly, it can still measure up to the best custom-design Radeon RX 7000 series cards out there. TUF Gaming, over the years, has evolved into an impressive custom-design brand from ASUS, which covers all the basics while also featuring high-end noise optimization, and overclocking features. While the card does include some basic ARGB lighting, it's not as much as you get on an ROG Strix product. If max RGB is your thing, then ASRock, Sapphire, or PowerColor have some jaw-dropping custom designs for you.
The AMD Radeon RX 7900 GRE isn't all that new—it was launched in mid-2023 as a China-exclusive limited edition SKU commemorating the Chinese year of the rabbit, hence the name Golden Rabbit Edition (GRE). This product is designed to fit between the RX 7900 XT and the RX 7800 XT in terms of performance, but with costs closer to the latter. AMD found itself disrupted in January 2024, when NVIDIA refreshed the higher end of its RTX 40-series with cards such as the RTX 4070 Super, which restored NVIDIA's competitiveness under the $600-mark, where the RX 7800 XT challenged the RTX 4070. AMD responded by simply giving the RX 7900 GRE a worldwide launch.
The Radeon RX 7900 GRE has an interesting product development story. The RX 7800 XT maxes out the Navi 32 silicon, and the only way AMD could create the RX 7900 GRE was by tapping into the larger Navi 31 silicon, and making its board partners use PCBs from the RX 7900 series—suboptimal when trying to compete in the $500-range. The company had developed a compacted version of the Navi 31, which it intended to use for mobile Radeon RX 7900 series SKUs. This is basically the Navi 31 chiplet GPU, but placed on a package that's exactly the size of the Navi 32, with a similar pin-map, and wiring for a 256-bit wide memory bus. AMD used this compact Navi 31 variant, and made its partners reuse PCBs and cooling solutions from their RX 7800 XT products, to create the RX 7900 GRE. Both SKUs have similar power limits, and so reusing the PCBs and coolers became easy.
The Radeon RX 7900 GRE is carved out of Navi 31 by enabling 80 out of the 96 RDNA 3 compute units present on the 5 nm GCD. This works out to 5,120 stream processors, 160 AI accelerators, 80 Ray accelerators, and 320 TMUs. 160 out of the 192 ROPs present are enabled. The chip has just four of the six memory cache dies (MCDs) enabled, each with a 16 MB segment of the Infinity Cache, and a 64-bit portion of the memory bus. It hence has 64 MB of Infinity Cache, and a 256-bit memory bus. What's interesting here is that AMD chose a lower memory speed for the RX 7900 GRE compared to the RX 7800 XT—18 Gbps vs. 19.5 Gbps. Perhaps every effort was made to bring the two SKUs to an identical power profile.
Powering the Radeon RX 7900 GRE is the AMD RDNA 3 graphics architecture, which introduces generational performance increases by leveraging the 5 nm process, at least where it matters. The new dual-issue rate compute unit offers an over 17% IPC increase over the RDNA 2 compute unit. The new AI accelerator is a component that prepares matrix math for further execution on the stream processors, greatly accelerating AI workloads; while the new 2nd generation Ray accelerator features a 50% performance improvement. AMD also introduced the multi-draw indirect accelerator (MDIA), a component that vastly speeds up Direct3D 12 workloads that use the multi-draw indirect instruction.
The ASUS TUF Gaming RX 7900 GRE features a similar cooling solution and PCB to the company's RX 7800 XT, for the reasons we explained above. This is a highly capable package, and ASUS has given the card a formidable fin-stack based cooling solution that uses its latest Axial-Tech fans. The metal cooler shroud gives it an industrial look, and is very airy for the heatsink underneath. There is minimal use of RGB, in the form of a single light strip. The card offers features such as dual-BIOS, and factory overclocked speeds of 1972 MHz Game Clocks (compared to 1880 MHz reference), while leaving the memory untouched at 18 Gbps. ASUS is pricing this card at $600, a reasonable $50 premium over the AMD baseline, but a price that puts it on par with the GeForce RTX 4070 Super.
