AMD Radeon PRO W7500 vs Intel Arc B770 Comparison

AMD Radeon PRO W7500 vs Intel Arc B770

The database comparison between the AMD Radeon PRO W7500 and the Intel Arc B770 presents two distinct GPU classes. The AMD card has recorded benchmark scores across nine tests, while the Intel card currently has no recorded benchmark scores in the database. This makes the comparison one of measured performance versus architectural specification, with the data indicating different intended workloads and system requirements.

Where Each One Wins

The AMD Radeon PRO W7500 wins in every currently recorded benchmark category because it is the only card with benchmark data. Its scores include 58,213 in Geekbench OpenCL, 68,634 in Geekbench Vulkan, 13,368 in Passmark G3D, and 5,910 in Passmark GPU Compute. The Intel Arc B770 has no benchmark entries, so no performance comparisons can be made from measured results.

The Intel Arc B770 wins in the specification-based categories that can be projected from its hardware configuration. It has a higher boost clock, more memory, a wider memory bus, more shading units, more texture mapping units, more render output units, more ray tracing cores, higher pixel rate, higher texture rate, and higher FP32 throughput. The data shows a card designed for higher absolute throughput, while the AMD card demonstrates what a 70 W GPU can achieve in professional workloads.

Architecture Differences

The AMD Radeon PRO W7500 uses the Navi 33 chip with RDNA 3.0 architecture on a 6 nm process from TSMC. The codename is Hotpink Bonefish, and it belongs to the Radeon Pro Navi generation. The chip contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter.

The Intel Arc B770 uses the BMG-G31 chip with Xe2-HPG architecture on a 5 nm process from TSMC. It belongs to the Battlemage generation, specifically the Arc 7 series. The die size is 368 mm², which is considerably larger than the AMD chip. Transistor count is listed as unknown, and the transistor density is not recorded.

The architectural approaches differ in core composition. The AMD card has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. The Intel card has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. The Intel card has more than double the shading units and TMUs, and double the ROPs. Neither card includes tensor cores in the database.

Both cards support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The process node difference, 6 nm versus 5 nm, combined with the larger Intel die, indicates different design priorities. The AMD card focuses on efficiency with a 70 W TDP, while the Intel card uses 225 W.

Head-to-Head Benchmarks

The head-to-head benchmark section in the database is empty. There are no recorded wins for either card in direct comparison tests. The AMD card has standalone benchmark scores, but the Intel card has none. This means the only quantitative performance data available belongs to the AMD Radeon PRO W7500.

The AMD card's average benchmark score is 16,415, placing it at the 59th percentile among all GPUs. Its nearest rivals in the database include the NVIDIA RTX PRO 6000 Blackwell with an average score of 16,408 and a delta of 0%, the AMD Radeon RX 5700 XT at 16,361 with a 0.3% delta, the AMD Radeon Pro 5600M at 16,351 with a 0.4% delta, and the NVIDIA GeForce RTX 5090 D V2 at 16,504 with a -0.5% delta. The data shows the W7500 sits in a tightly packed performance band, within half a percent of four other cards.

The individual benchmark scores for the AMD card show its strengths. The Passmark DirectX 9 score of 200 is the highest of its Passmark DirectX tests, followed by DirectX 11 at 125, DirectX 10 at 65, and DirectX 12 at 46. The Passmark G2D score is 1,174, and the Passmark G3D score is 13,368. The Passmark GPU Compute score of 5,910 indicates compute capability that is separate from graphics rendering.

For the Intel Arc B770, the absence of benchmark data means the only comparison available is against its own specifications. The FP32 throughput of 19.66 TFLOPS and FP16 throughput of 39.32 TFLOPS (2:1) are recorded figures that would position it above the AMD card in raw compute, but no measured test confirms this.

Specification Differences

The two cards differ across nearly every major specification field. The AMD Radeon PRO W7500 has 8 GB of GDDR6 memory on a 128-bit bus with 256.0 GB/s bandwidth. The Intel Arc B770 has 16 GB of GDDR6 memory on a 256-bit bus with 512.0 GB/s bandwidth. The Intel card has double the memory capacity, double the bus width, and double the bandwidth.

Clock speeds differ significantly. The AMD card has a base clock of 1500 MHz and a boost clock of 1700 MHz. The Intel card has a base clock of 2100 MHz and a boost clock of 2400 MHz. The Intel card's boost clock is 700 MHz higher than the AMD card's boost clock. Memory clocks are similar at 2000 MHz with 16 Gbps effective for both cards.

The power requirements show a clear separation. The AMD card has a TDP of 70 W, no power connectors, a suggested PSU of 250 W, and a single-slot design. The Intel card has a TDP of 225 W, requires one 6-pin and one 8-pin power connector, a suggested PSU of 550 W, and a dual-slot design. The Intel card draws more than three times the power of the AMD card.

The PCIe interface differs as well. The AMD card uses PCIe 4.0 x8, while the Intel card uses PCIe 4.0 x16. The display outputs also vary: the AMD card has four DisplayPort 2.1 outputs, while the Intel card has one HDMI 2.1a and three DisplayPort 2.1 outputs.

Physical dimensions are only recorded for the AMD card: 216 mm length (8.5 inches), 115 mm height (4.5 inches), and 20 mm width (0.8 inches). The Intel card has no recorded dimensions. The production status for the AMD card is Active, while the Intel card has no production status recorded. The release dates differ: the AMD card was released on 2023-08-02, while the Intel card is dated 2025-12-31. The AMD card's predecessor is the Radeon Pro Vega, and the Intel card's predecessor is Alchemist. The AMD card has a launch MSRP of 429 USD, while the Intel card has no launch MSRP recorded.

The Verdict

The data shows two cards designed for different roles. The AMD Radeon PRO W7500 is a 70 W, single-slot card with no power connectors, suitable for systems with a 250 W PSU. It has recorded benchmark scores that place it at the 59th percentile, with an average score of 16,415, nearly identical to the NVIDIA RTX PRO 6000 Blackwell. Its four DisplayPort 2.1 outputs and compact dimensions of 216 mm by 115 mm by 20 mm indicate a workstation-oriented card for multi-display setups.

The Intel Arc B770 is a higher-power design at 225 W with dual-slot cooling, requiring a 550 W PSU and two power connectors. Its specifications point to higher peak performance: 19.66 TFLOPS FP32, 512.0 GB/s memory bandwidth, 16 GB of VRAM, and a 2400 MHz boost clock. However, no benchmark scores exist in the database to confirm this performance. The card's release date is listed as 2025-12-31, and it has no launch MSRP.

Users who need verified performance data should select the AMD card, as its benchmark scores are recorded and its nearest rivals show it performs within half a percent of cards like the RTX PRO 6000 Blackwell. Users who require maximum memory capacity and bandwidth, and who can accommodate a 225 W TDP with a dual-slot card, would look to the Intel card based on its specifications alone, but should recognize that no measured scores support those specifications yet. The choice between the two cards comes down to whether recorded data or projected hardware capability takes priority.
