AMD Radeon PRO W7900D vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the AMD Radeon PRO W7900D and Intel Arc Pro B65. Both cards have an average benchmark score of zero and hold identical percentile rankings at 50th overall, which means no direct performance measurements are available to compare. The absence of benchmark data is a significant finding in itself: the database currently provides no quantitative evidence for raw compute, rasterization, or ray tracing comparisons between these two workstation accelerators.

What the data does show is a dramatic gap in theoretical specifications. The AMD Radeon PRO W7900D delivers 52.99 TFLOPS of FP32 compute, while the Intel Arc Pro B65 delivers 12.29 TFLOPS. That is a 4.31x advantage for AMD in single-precision floating-point throughput. In FP16, AMD maintains 52.99 TFLOPS with a 1:1 ratio, whereas Intel reaches 24.58 TFLOPS with a 2:1 ratio. AMD leads FP16 by 2.16x. These are not benchmark results; they are peak compute ratings from the specification sheets, but they indicate the scale of the architectural capability gap.

Memory bandwidth follows a similar pattern. The AMD card uses a 384-bit bus with 48 GB of GDDR6 and reaches 864.0 GB/s. The Intel card uses a 256-bit bus with 32 GB of GDDR6 and reaches 608.0 GB/s. AMD provides 1.42x the bandwidth and 1.5x the memory capacity. Pixel throughput on AMD is 414.0 GPixel/s versus 192.0 GPixel/s on Intel, a 2.16x margin. Texture throughput on AMD is 827.9 GTexel/s versus 384.0 GTexel/s, a 2.16x margin as well.

Clock speeds tell a different story. The Intel Arc Pro B65 runs at a fixed 2400 MHz for both base and boost, while the AMD Radeon PRO W7900D has a base clock of 1327 MHz and a boost clock of 2156 MHz. Intel's sustained clock is 11.3% higher than AMD's boost clock and 80.9% higher than AMD's base clock. That higher clock does not compensate for the massive difference in shading units: AMD has 6144 shading units, 384 TMUs, and 192 ROPs, while Intel has 2560 shading units, 160 TMUs, and 80 ROPs. AMD has 2.4x the shading units, 2.4x the TMUs, and 2.4x the ROPs.

Ray tracing hardware also diverges. AMD integrates 96 RT cores, while Intel integrates 20 RT cores. That is a 4.8x difference in dedicated ray tracing hardware count. No benchmark scores exist to translate that into frame rates, but the hardware ratio is unambiguous.

Where Each One Wins

Based on specification data alone, the AMD Radeon PRO W7900D wins every measurable compute and memory category. It has more shading units, more TMUs, more ROPs, more RT cores, higher FP32 throughput, higher FP16 throughput, higher pixel rate, higher texture rate, larger memory capacity, wider memory bus, and higher memory bandwidth. The 48 GB frame buffer is 50% larger than the 32 GB on Intel, which matters for large dataset workloads such as machine learning inference, high-resolution rendering, and complex simulations that exceed 32 GB of working set.

The Intel Arc Pro B65 wins in two specific areas. First, clock speed: 2400 MHz base and boost on Intel versus 1327 MHz base and 2156 MHz boost on AMD. For workloads that are latency-bound rather than throughput-bound, the higher sustained clock could provide an advantage, though the much lower core count limits the impact. Second, power efficiency per clock: Intel consumes 200 W TDP versus 295 W TDP on AMD, a 32.2% lower power draw. Per FP32 TFLOPS, Intel consumes 16.3 W per TFLOPS (200 W divided by 12.29 TFLOPS), while AMD consumes 5.57 W per TFLOPS (295 W divided by 52.99 TFLOPS). AMD is 2.92x more efficient in terms of FP32 throughput per watt.

The Intel card also uses a PCIe 5.0 x16 bus interface, while the AMD card uses PCIe 4.0 x16. PCIe 5.0 doubles the theoretical bandwidth of the bus, which can benefit data transfer between the GPU and system memory for workloads that stream large datasets. The AMD card has a larger die at 529 mm² versus 272 mm², with more transistors at 57,700 million versus 19,600 million. Transistor density is 109.1M per mm² on AMD versus 72.1M per mm² on Intel, indicating a denser design on the same 5 nm TSMC process node.

The Verdict

The data supports a clear conclusion: the AMD Radeon PRO W7900D is the higher-performance workstation GPU in every computed metric recorded in the database. It delivers 4.31x the FP32 throughput, 2.16x the FP16 throughput, 2.16x the pixel rate, 2.16x the texture rate, 1.42x the memory bandwidth, and 1.5x the memory capacity compared to the Intel Arc Pro B65. The 96 RT cores versus 20 RT cores further cements AMD's position for ray-traced workloads.

The Intel Arc Pro B65 does hold advantages in clock speed (2400 MHz versus 2156 MHz boost), power draw (200 W versus 295 W), and bus interface (PCIe 5.0 versus PCIe 4.0). For users constrained by power delivery or physical slot width, the Intel card is dual-slot versus triple-slot on AMD, and uses a single 8-pin power connector versus dual 8-pin on AMD. The suggested power supply is 550 W for Intel versus 600 W for AMD. These are meaningful for system integration.

However, the performance gap is so large that the Intel card cannot be positioned as a competitor to the AMD card in raw compute. The database shows no benchmark scores, so the verdict rests entirely on specification analysis. The AMD Radeon PRO W7900D is the choice for workloads that demand maximum FP32, FP16, ray tracing, memory capacity, and bandwidth. The Intel Arc Pro B65 is the choice for deployments where lower power draw, higher clock speed, PCIe 5.0 connectivity, and a smaller physical footprint are priorities, accepting a significant reduction in throughput.
