AMD Radeon 8065S vs AMD Radeon PRO W7900D Comparison

Where Each One Wins

The AMD Radeon 8065S and AMD Radeon PRO W7900D occupy different corners of the GPU landscape, and the recorded data shows a clear split in their intended roles. The 8065S is a mobile-class integrated graphics processor built for portable devices, while the W7900D is a professional workstation card designed for sustained, high-throughput compute and multi-display environments.

Based on the benchmark data, the W7900D claims the overwhelming majority of performance wins. Its raw compute specifications dwarf those of the 8065S in nearly every measurable category. The W7900D delivers 52.99 TFLOPS of FP32 performance and 52.99 TFLOPS of FP16 performance, both at a 1:1 ratio, compared to the 8065S's 15.36 TFLOPS in each precision. That represents a 3.45x advantage in raw shader throughput for the workstation card. Similarly, the W7900D's texture rate of 827.9 GTexel/s is 1.72x higher than the 8065S's 480.0 GTexel/s, and its pixel rate of 414.0 GPixel/s is 2.16x higher than the 8065S's 192.0 GPixel/s.

The 8065S, however, wins in the categories that matter for its form factor. It operates at a 55 W TDP, a figure that is 5.36x lower than the W7900D's 295 W TDP. The 8065S is an integrated graphics processor (IGP) with no power connectors and no slot width, meaning it fits directly into a portable device's motherboard. The W7900D, by contrast, is a triple-slot card measuring 280 mm in length, 110 mm in height, and 51 mm in width, requiring two 8-pin power connectors and a 600 W suggested power supply. For thin-and-light laptops, compact desktops, or any system where physical space and thermal headroom are constrained, the 8065S is the only viable option between the two.

The clock speed profile also favors the 8065S in one specific regard. Its boost clock of 3000 MHz is substantially higher than the W7900D's 2156 MHz boost, and its base clock of 1295 MHz is slightly lower than the W7900D's 1327 MHz. This suggests the 8065S is designed to burst to high frequencies for short workloads, while the W7900D maintains a more conservative clock curve for sustained compute tasks.

Architecture Differences

The two GPUs come from different architectural generations, which explains many of their performance and feature disparities. The 8065S is built on RDNA 3.5, the latest iteration of AMD's graphics architecture, and uses the Gorgon Halo chip. It belongs to the Navi Mobile (RX 8000M) generation. The W7900D, meanwhile, uses RDNA 3.0 architecture with the Navi 31 chip, codenamed Plum Bonito, and is part of the Radeon Pro Navi (Navi III Series) generation.

The manufacturing process differs as well. The 8065S is fabricated on a 4 nm process at TSMC, while the W7900D uses a 5 nm process, also at TSMC. The die sizes reflect the different design goals: the 8065S has a 308 mm² die, while the W7900D has a much larger 529 mm² die. The W7900D also has a publicly listed transistor count of 57,700 million, with a transistor density of 109.1M per mm². The 8065S's transistor count is listed as unknown in the database.

The memory subsystems are fundamentally different. The 8065S uses system shared memory, meaning its memory size, type, bus width, and bandwidth are all system dependent. The W7900D, in contrast, has a dedicated 48 GB GDDR6 memory pool on a 384-bit bus, delivering 864.0 GB/s of bandwidth. Its memory clock is 2250 MHz, or 18 Gbps effective. This dedicated memory configuration is critical for professional workloads that require large datasets to reside on the GPU without competing with the CPU for system RAM.

Shader core counts also diverge sharply. The 8065S has 2560 shading units, 160 texture mapping units, 64 render output units, and 40 ray tracing cores. The W7900D has 6144 shading units, 384 TMUs, 192 ROPs, and 96 ray tracing cores. The workstation card has 2.4x the shading units, 2.4x the TMUs, 3x the ROPs, and 2.4x the ray tracing cores of the mobile IGP.

The bus interface also differs: the 8065S uses PCIe 5.0 x16, while the W7900D uses PCIe 4.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither card has tensor cores listed in the database.

Head-to-Head Benchmarks

The head-to-head benchmark section in the database is empty for this pairing, meaning there are no directly recorded comparative scores between the 8065S and the W7900D. However, the specification-level data provides clear numerical deltas that indicate where each card would dominate in a direct comparison.

The largest single-metric gap is in raw FP32 compute. The W7900D's 52.99 TFLOPS is 37.63 TFLOPS higher than the 8065S's 15.36 TFLOPS, a 3.45x multiplier. In workloads that scale with shader throughput, such as 3D rendering, scientific simulation, and machine learning inference (where FP32 is the primary precision), the W7900D would finish tasks in roughly one-third the time of the 8065S.

Memory bandwidth is another decisive divider. The W7900D's 864.0 GB/s is a fixed, dedicated resource, while the 8065S's bandwidth is labeled "System Dependent" and cannot be quantified from the database. In practice, this means the W7900D can feed its 6144 shading units without stalling, while the 8065S must share system memory bandwidth with the CPU, which is a bottleneck for memory-intensive workloads.

The texture rate differential is also substantial. The W7900D's 827.9 GTexel/s versus the 8065S's 480.0 GTexel/s means the workstation card can process nearly twice as many texture samples per second. This affects games and 3D applications that rely heavily on textured surfaces, though the 8065S's higher boost clock of 3000 MHz versus 2156 MHz helps close the gap in lighter, less demanding scenes.

Pixel fill rate favors the W7900D at 414.0 GPixel/s versus 192.0 GPixel/s. This matters for high-resolution rendering, particularly at 4K and above, where the number of pixels to be shaded per frame increases dramatically. The W7900D's 2.16x advantage in this metric would show up as higher frame rates or faster render times at high resolutions.

Ray tracing is another area where the W7900D holds a clear edge. It has 96 ray tracing cores versus 40 on the 8065S, a 2.4x difference. For ray-traced workloads, whether in DXR-based games or professional visualization tools, the W7900D would process significantly more rays per second.

The 8065S's only clear specification win is in boost clock frequency, where its 3000 MHz exceeds the W7900D's 2156 MHz by 844 MHz. In short, bursty workloads that are latency-bound rather than throughput-bound might see a benefit from the 8065S's higher clock, but this is unlikely to offset the massive core count and memory bandwidth advantages of the W7900D in sustained compute tasks.
