AMD Radeon 8065S vs AMD Radeon RX 7900 GRE Comparison

The AMD Radeon 8065S and the AMD Radeon RX 7900 GRE occupy distinctly different positions in the database. The 8065S is a mobile integrated graphics processor built on the Gorgon Halo chip, while the 7900 GRE is a dedicated desktop add-in board. The benchmark data available for these two GPUs is asymmetrical: the 8065S currently has no recorded benchmark scores, whereas the 7900 GRE has a full suite of results across multiple test suites. This disparity dictates that the analysis focuses on the architectural and specification differences, with the 7900 GRE's measured performance serving as the only quantitative baseline.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons are not possible with the current data. The AMD Radeon 8065S has no benchmark entries in the database, resulting in zero recorded wins and an average benchmark score of zero. In contrast, the AMD Radeon RX 7900 GRE has ten recorded benchmark scores across 3DMark, Geekbench, and Passmark suites, with an average benchmark score of 32456. This places the 7900 GRE at the 77th percentile among all GPUs in the database, while the 8065S sits at the 50th percentile based on its incomplete profile, which should not be interpreted as a performance equivalence.

The 7900 GRE's strongest recorded result comes from Geekbench OpenCL, where it scores 175758 points. Its Vulkan performance in Geekbench is also substantial at 99850 points. In the Passmark suite, the G3D score of 27089 and the GPU Compute score of 15016 represent the card's direct rendering and compute capabilities, respectively. The 3DMark Steel Nomad DX12 test shows a score of 4814, which is a modern DirectX 12 workload. Legacy DirectX performance in Passmark shows scores of 310 for DirectX 9, 300 for DirectX 11, 139 for DirectX 10, and 107 for DirectX 12, with a G2D score of 1180 for 2D operations.

The 7900 GRE's nearest rivals in the database provide context for its standing. The AMD FirePro S10000 has an average score of 32388, which is 0.2 percent lower than the 7900 GRE. The AMD FirePro S9300 X2 scores 32540, a 0.3 percent difference in favor of the older card. The AMD Radeon RX 590 GME averages 32601, outperforming the 7900 GRE by 0.4 percent. The AMD Radeon Pro 570X scores 32176, which is 0.9 percent lower. These deltas, all under one percent, indicate that the 7900 GRE's average score of 32456 places it in a tightly clustered band of mid-range performers from various generations.

Where Each One Wins

Based on the recorded data, the AMD Radeon RX 7900 GRE wins across every benchmark category where measurements exist. Its pixel rate is listed as 359.2 GPixel/s, and its texture rate is 718.4 GTexel/s, figures that reflect its 160 ROPs and 320 TMUs. The 8065S offers a pixel rate of 192.0 GPixel/s and a texture rate of 480.0 GTexel/s, but without benchmark scores, these theoretical rates cannot be validated in real-world workloads. The 7900 GRE's FP32 compute is 45.98 TFLOPS, and its FP16 compute is 91.96 TFLOPS with a 2:1 ratio. The 8065S delivers 15.36 TFLOPS for both FP32 and FP16 at a 1:1 ratio, meaning its half-precision throughput does not double, which is a characteristic of its RDNA 3.5 architecture iteration.

The use-case split is therefore one-sided in the data. The 7900 GRE is the only card with measurable performance in DirectX 12 Ultimate workloads, as shown by its 3DMark Steel Nomad score. It also handles OpenCL and Vulkan compute tasks, demonstrated by its Geekbench scores. The 8065S, as a mobile integrated processor with system-shared memory, has no dedicated benchmark results, so there is no recorded workload in which it demonstrates a win. Its advantages would have to be inferred from its lower power envelope and integrated nature, but the database contains no performance numbers to substantiate any such claim.

Architecture Differences

The architectural gap between these two GPUs is substantial. The 8065S uses the Gorgon Halo chip built on RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC. The 7900 GRE uses the Navi 31 chip built on RDNA 3.0, fabricated on a 5 nm process at TSMC. The 8065S has a die size of 308 mm² with transistor count listed as unknown, while the 7900 GRE has a 529 mm² die containing 57,700 million transistors, resulting in a transistor density of 109.1M per mm². The 8065S belongs to the Navi Mobile (RX 8000M) generation, whereas the 7900 GRE is part of the Navi III (RX 7000) series with the codename Plum Bonito.

Memory configurations differ fundamentally. The 8065S uses system-shared memory with a system-dependent bandwidth, meaning it borrows from the host system's RAM. The 7900 GRE has 16 GB of dedicated GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth at 18 Gbps effective speed. This dedicated memory arrangement is a primary factor in the 7900 GRE's ability to sustain high throughput. The 8065S has no memory bus width or type of its own, as it relies entirely on the system.

Execution resources are heavily skewed toward the 7900 GRE. It has 5120 shading units, 320 texture mapping units, 160 ROPs, and 80 ray tracing cores. The 8065S has 2560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores, exactly half the 7900 GRE's count in each category. Clock speeds tell a different story: the 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz, while the 7900 GRE runs at 1287 MHz base, 1880 MHz game clock, and 2245 MHz boost. The 8065S's higher boost clock partially compensates for its fewer cores, but its FP32 throughput of 15.36 TFLOPS is roughly one-third of the 7900 GRE's 45.98 TFLOPS.

Power and physical design are also divergent. The 8065S has a TDP of 55 W and is an integrated graphics processor with no power connectors and no slot width, designed to be soldered onto a portable device's motherboard. The 7900 GRE has a 260 W TDP, is dual-slot, uses two 8-pin power connectors, and requires a 600 W suggested PSU. The 7900 GRE's dimensions are 276 mm in length, 110 mm in height, and 51 mm in width. The 8065S has no listed dimensions because it is not a standalone card. The 8065S uses a PCIe 5.0 x16 interface, while the 7900 GRE uses PCIe 4.0 x16. Display outputs also differ: the 8065S is portable device dependent, while the 7900 GRE provides 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates that the AMD Radeon RX 7900 GRE is the only one of these two GPUs with measurable performance in the database. Its average benchmark score of 32456 and 77th percentile ranking place it among the better-performing cards, with nearest rivals all within 0.9 percent of its score. The 8065S, with no benchmarks and a 0 average score, cannot be compared on performance merits. The 7900 GRE's 45.98 TFLOPS FP32 compute, 16 GB of GDDR6 memory, and 576.0 GB/s bandwidth establish it as a dedicated desktop solution for demanding workloads. The 8065S, with 15.36 TFLOPS FP32 and system-shared memory, is architecturally suited for integrated mobile use, but the lack of recorded scores means the database cannot verify its real-world capabilities. Users requiring a discrete GPU with proven benchmark results should consider the 7900 GRE. Users seeking a low-power integrated solution in a portable device would evaluate the 8065S, but no performance data exists to support any specific expectations.
