AMD Radeon PRO W7800 vs Intel Arc Pro B65 Comparison

AMD Radeon PRO W7800 vs Intel Arc Pro B65

Where Each One Wins

The benchmark database contains a stark asymmetry in recorded performance data for these two workstation GPUs. The AMD Radeon PRO W7800 has two completed benchmark submissions, while the Intel Arc Pro B65 currently has zero recorded benchmark scores, placing it at the 50th percentile among all GPUs in the database with an average benchmark score of zero. The AMD card sits at the 97th percentile with an average benchmark score of 164,894.

This means the use-case split is defined by what the data can actually show. The AMD Radeon PRO W7800 is the only one of the two with measurable compute performance. In Geekbench OpenCL, it records 154,366 points, and in Geekbench Vulkan, it records 175,422 points. The Intel Arc Pro B65 has no comparable entries, so there is no recorded basis for a workload where it wins outright.

The AMD card's nearest rivals in the database are all NVIDIA professional parts and one AMD predecessor. It trails the NVIDIA RTX 4500 Ada Generation by 0.7 percent, trails the NVIDIA RTX A5500 by 0.2 percent, and trails the AMD Radeon Pro W6900X by 2.2 percent. It leads the NVIDIA A100 PCIe 40 GB by 1.5 percent. These are narrow margins, indicating the W7800 lands in a competitive performance band rather than dominating or lagging badly.

For the Intel Arc Pro B65, the absence of benchmark data means the database cannot assign any workload wins. The card is marked as Active production status with a release date of 2026-03-31, which is later than the AMD card's 2023-04-12 release. The Intel part simply has not yet generated performance records in the database. The practical interpretation is that the AMD card currently owns every measurable use case, while the Intel card's capabilities remain undocumented.

Architecture Differences

The two cards diverge fundamentally in their underlying designs. The AMD Radeon PRO W7800 uses the Navi 31 chip with the RDNA 3.0 architecture, codenamed Plum Bonito, from the Radeon Pro Navi generation. The Intel Arc Pro B65 uses the BMG-G21 chip with the Xe2-HPG architecture from the Battlemage Pro Series generation.

Both are built on TSMC's 5 nm process, but the transistor counts differ enormously. The AMD chip contains 57,700 million transistors on a 529 mm² die, producing a transistor density of 109.1 million per square millimeter. The Intel chip contains 19,600 million transistors on a 272 mm² die, with a density of 72.1 million per square millimeter. The AMD die is nearly twice the physical size and packs nearly three times the transistor count.

Both cards use 32 GB of GDDR6 memory on a 256-bit bus. The AMD memory runs at 2250 MHz with 18 Gbps effective speed, yielding 576.0 GB/s bandwidth. The Intel memory runs at 2375 MHz with 19 Gbps effective speed, yielding 608.0 GB/s bandwidth. The Intel card actually has a slight memory bandwidth advantage, 608.0 GB/s versus 576.0 GB/s, despite the smaller chip.

The compute resource counts show a large gap. The AMD card has 4480 shading units, 280 texture mapping units, 128 render output units, and 70 ray tracing cores. The Intel card has 2560 shading units, 160 texture mapping units, 80 render output units, and 20 ray tracing cores. The AMD card leads in every count, with the ray tracing core difference being particularly large at 70 versus 20.

Clock behavior also differs. The AMD card has a base clock of 1895 MHz and a boost clock of 2525 MHz, so it runs faster under load. The Intel card has a flat 2400 MHz for both base and boost, meaning no boost headroom above its base frequency.

The interface and power delivery differ as well. The AMD card uses PCIe 4.0 x16, while the Intel card uses PCIe 5.0 x16, giving the Intel part a newer bus standard. The AMD card draws 260 W TDP with two 8-pin power connectors and a suggested 600 W power supply. The Intel card draws 200 W TDP with a single 8-pin connector and a suggested 550 W power supply.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two specific cards, and the Intel Arc Pro B65 has no individual benchmark scores at all. The only comparable data points come from the AMD card's standalone results and its nearest rival comparisons.

The AMD Radeon PRO W7800's Geekbench Vulkan score of 175,422 is higher than its Geekbench OpenCL score of 154,366, a difference of roughly 13.6 percent in favor of Vulkan. This indicates the RDNA 3.0 architecture performs better under the Vulkan API in this particular workload.

In the nearest rival comparison, the AMD card's average score of 164,894 sits within a tight band. The NVIDIA RTX A5500 averages 165,217, just 0.2 percent higher. The NVIDIA RTX 4500 Ada Generation averages 166,094, 0.7 percent higher. The AMD Radeon Pro W6900X averages 168,574, 2.2 percent higher. Only the NVIDIA A100 PCIe 40 GB, at 162,504, falls below the W7800 by 1.5 percent.

The practical implications of these numbers are that the AMD card is competitive with several high-end professional GPUs, but it does not hold the top position among its recorded neighbors. The 2.2 percent gap to the W6900X is the largest deficit, while the 0.2 percent gap to the RTX A5500 is nearly negligible.

For the Intel Arc Pro B65, the absence of scores means no comparison is possible. The database lists its percentile as 50, which is the midpoint of the distribution, but that value derives from having no benchmark data rather than from measured performance. The card's average benchmark score is listed as zero, which confirms that no completed test has been recorded.

The performance data that does exist for the AMD card, however, gives a concrete picture. The pixel rate of 323.2 GPixel/s and texture rate of 707.0 GTexel/s are direct measurements of fill and texturing throughput. The FP32 compute of 45.25 TFLOPS and FP16 of 90.50 TFLOPS at 2:1 ratio show a card designed for heavy floating-point workloads. The Intel card's corresponding figures are 192.0 GPixel/s, 384.0 GTexel/s, 12.29 TFLOPS FP32, and 24.58 TFLOPS FP16 at 2:1 ratio. These specification-derived rates are far lower on the Intel side, but they are not benchmark scores and cannot be directly compared as measured results.

The Verdict

The recorded data favors the AMD Radeon PRO W7800 in every measurable category. It has an average benchmark score of 164,894 versus zero for the Intel Arc Pro B65. It holds the 97th percentile among all GPUs, while the Intel card sits at the 50th percentile. It has completed Geekbench OpenCL and Vulkan runs, while the Intel card has none.

For a user selecting strictly based on database evidence, the AMD card is the only option with demonstrated performance. The Intel Arc Pro B65 is an Active product with a 2026 release date, but its performance profile is entirely unrecorded. The database cannot confirm any workload capability for it.

The AMD card's position within its nearest rivals also matters. It is competitive with the NVIDIA RTX A5500 and RTX 4500 Ada Generation, with gaps of 0.2 and 0.7 percent respectively. It leads the NVIDIA A100 PCIe 40 GB by 1.5 percent. These margins are small, meaning the W7800 is not an outlier but rather a solid mid-to-high performer among professional GPUs.

The Intel card does have structural advantages on paper. Its PCIe 5.0 x16 interface is newer than the AMD card's PCIe 4.0 x16. Its memory bandwidth of 608.0 GB/s exceeds the AMD card's 576.0 GB/s. Its power draw of 200 W is lower than the AMD card's 260 W, and it requires only a single 8-pin connector versus two. These are relevant for system integration and power efficiency, but they do not substitute for missing benchmark scores.

The verdict from the data is straightforward. The AMD Radeon PRO W7800 is the only card in this comparison with recorded performance, and that performance places it in the upper tier of professional GPUs. The Intel Arc Pro B65 is a newer product with modern interfaces and lower power requirements, but its actual compute capabilities remain unknown in the database.
