AMD Radeon 8065S vs NVIDIA GB10 Comparison

AMD Radeon 8065S vs NVIDIA GB10

Head-to-Head Benchmarks

The benchmark database contains no direct head-to-head comparison results between the AMD Radeon 8065S and the NVIDIA GB10. The Radeon 8065S has zero recorded benchmark scores, an average benchmark score of 0, and no nearest rivals listed. The GB10, by contrast, has two recorded benchmark results: a Geekbench OpenCL score of 120137 and a Geekbench Vulkan score of 114648, producing an average benchmark score of 117393. This places the GB10 in the 95th percentile of all GPUs, while the Radeon 8065S sits at the 50th percentile.

The GB10’s average score of 117393 positions it narrowly ahead of the NVIDIA RTX 4000 SFF Ada Generation, which averages 117088, a margin of 0.3 percent. It trails the AMD Radeon PRO W7700, which averages 118976, by 1.3 percent. Against the NVIDIA Tesla V100 SXM2 16 GB, which averages 114395, the GB10 leads by 2.6 percent. The NVIDIA RTX A5500 Mobile averages 113944, placing the GB10 3 percent ahead. These results indicate that the GB10 competes directly with professional workstation-class GPUs, delivering scores within a narrow band of those established products.

Without recorded benchmarks for the Radeon 8065S, the database cannot quantify its performance relative to the GB10. The data shows a substantial gap in recorded performance evidence: the GB10 has verified, reproducible scores while the Radeon 8065S has none. The Radeon 8065S’s percentile ranking of 50 suggests it sits at the median of all GPUs, but this ranking is not supported by any individual benchmark result in the database, making direct numerical comparison impossible.

The Verdict

From the recorded data alone, the NVIDIA GB10 is the only unit with measurable performance. Its average benchmark score of 117393, its 95th percentile standing, and its favorable comparisons against four established rivals give it a clear, evidence-backed position. The AMD Radeon 8065S, with no benchmark scores and a 50th percentile ranking, cannot be validated through the same lens. The GB10 also carries a launch MSRP of 3,999 USD, a figure stated once here for reference.

The Radeon 8065S’s specifications suggest a different design intent: a 55 W integrated graphics processor with system-shared memory, compared to the GB10’s 140 W integrated graphics processor with 128 GB of dedicated LPDDR5X memory. The GB10’s memory configuration, with a 256 bit bus and 273.2 GB/s bandwidth, provides a concrete advantage in memory capacity and throughput. The Radeon 8065S’s memory bandwidth is listed as system dependent, meaning its performance would vary based on the host system’s memory configuration, an uncontrolled variable absent from the GB10’s fixed specifications.

Users seeking a validated, high-performance part with established benchmark results should select the GB10. Users considering the Radeon 8065S must rely on its architectural and specification profile alone, as the database contains no performance evidence to support a purchase decision. The data does not support a recommendation for the Radeon 8065S based on measured performance, as none exists.

Architecture Differences

The two GPUs implement fundamentally different architectures. The AMD Radeon 8065S uses RDNA 3.5, built on the Gorgon Halo chip, and belongs to the Navi Mobile (RX 8000M) generation. It is fabricated on a 4 nm process at TSMC with a die size of 308 mm². The NVIDIA GB10 uses Blackwell 2.0, built on the GB20B chip, and belongs to the Server Blackwell (Bxx) generation. It is fabricated on a 5 nm process at TSMC with a die size of 382 mm².

The Radeon 8065S’s predecessor is Polaris Mobile, while the GB10’s predecessor is Server Hopper, and its successor is Server Rubin. These lineage differences reflect distinct market positions: the Radeon 8065S follows a mobile graphics lineage, while the GB10 follows a server compute lineage.

The Radeon 8065S supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, indicating full graphics API support for gaming and general rendering workloads. The GB10 lists DirectX, OpenGL, and Vulkan as N/A, indicating it is not designed for conventional graphics API workloads. This architectural distinction is decisive: the Radeon 8065S is a graphics-oriented processor, while the GB10 is a compute-oriented processor.

The Radeon 8065S includes 40 ray tracing cores, while the GB10 includes 48 ray tracing cores and 384 tensor cores. The Radeon 8065S lists no tensor cores. The GB10’s tensor core count suggests a strong focus on AI and compute workloads, a capability absent from the Radeon 8065S’s specification sheet.

Specification Differences

The two processors diverge sharply across nearly every specification field. The Radeon 8065S operates at a base clock of 1295 MHz and a boost clock of 3000 MHz. The GB10 operates at a base clock of 1665 MHz and a boost clock of 2418 MHz, with memory clocked at 1067 MHz or 8.5 Gbps effective. The Radeon 8065S’s memory is system shared, meaning its size, type, bus width, and bandwidth are all system dependent. The GB10 has 128 GB of LPDDR5X memory on a 256 bit bus, delivering 273.2 GB/s of bandwidth.

The Radeon 8065S contains 2560 shading units, 160 texture mapping units, and 64 raster output units. The GB10 contains 6144 shading units, 384 texture mapping units, and 48 raster output units. The Radeon 8065S has 40 ray tracing cores; the GB10 has 48. The GB10 has 384 tensor cores; the Radeon 8065S has none.

Pixel and texture rates differ substantially. The Radeon 8065S achieves 192.0 GPixel/s and 480.0 GTexel/s. The GB10 achieves 116.1 GPixel/s and 928.5 GTexel/s. The Radeon 8065S leads in pixel fill rate, while the GB10 leads in texture fill rate by a wide margin. Floating point performance shows the GB10 at 29.71 TFLOPS for both FP32 and FP16 (1:1), while the Radeon 8065S delivers 15.36 TFLOPS for both FP32 and FP16 (1:1). The GB10’s FP32 throughput is nearly double the Radeon 8065S’s.

Power and physical specifications also differ. The Radeon 8065S has a TDP of 55 W, while the GB10 has a TDP of 140 W and a suggested PSU of 300 W. Both use no power connectors and occupy an IGP slot width. The GB10 has physical dimensions of 150 mm by 51 mm by 150 mm (5.9 inches by 2 inches by 5.9 inches); the Radeon 8065S lists no dimensions.

Where Each One Wins

The AMD Radeon 8065S wins in scenarios tied to its architectural strengths. Its 192.0 GPixel/s pixel rate exceeds the GB10’s 116.1 GPixel/s, giving it a clear advantage in rasterization-heavy workloads. Its DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support make it suitable for conventional graphics rendering, which the GB10 does not support at all. Its 3000 MHz boost clock and 55 W TDP indicate a lower-power design suitable for portable or integrated deployments. Its 64 raster output units exceed the GB10’s 48, further reinforcing its pixel-processing advantage.

The NVIDIA GB10 wins in compute-intensive and memory-bound scenarios. Its 29.71 TFLOPS FP32 performance is nearly double the Radeon 8065S’s 15.36 TFLOPS. Its 928.5 GTexel/s texture rate far exceeds the Radeon 8065S’s 480.0 GTexel/s. Its 128 GB of LPDDR5X memory with 273.2 GB/s bandwidth provides a massive capacity and bandwidth advantage over the Radeon 8065S’s system-dependent memory. Its 384 tensor cores enable AI and deep learning workloads that the Radeon 8065S cannot perform, as it lists no tensor cores. Its 95th percentile benchmark standing and verified scores of 120137 in OpenCL and 114648 in Vulkan demonstrate proven compute performance, while the Radeon 8065S has no comparable evidence.

The GB10 also wins in consistency and predictability. Its fixed memory configuration, defined dimensions, and specified power requirements allow for reliable system integration. The Radeon 8065S’s system-dependent memory and portable-device-dependent display outputs introduce variability that the GB10 avoids. For users prioritizing measured performance, compute capability, and memory capacity, the GB10 is the data-supported choice. For users prioritizing low power consumption, pixel throughput, and graphics API compatibility, the Radeon 8065S presents a specification-based argument, though without benchmark validation.
