Intel Arc B770 vs Intel Arc Pro B50 Comparison

Head-to-Head Benchmarks

The Intel Arc B770 and Intel Arc Pro B50 share the same Xe2-HPG architecture and 16 GB of GDDR6 memory, but the benchmark data shows two very different performance classes. The B770 is the larger, faster part by every compute and graphics metric recorded in the database. The B50, by contrast, is a low-power professional card whose recorded scores place it near the bottom of the overall GPU distribution.

The most direct comparison comes from raw shader throughput. The Arc B770 delivers 19.66 TFLOPS of FP32 compute, while the Arc Pro B50 delivers 10.65 TFLOPS. That is a 1.85x advantage for the B770, a gap that appears consistently across texture and pixel processing. The B770 reaches 614.4 GTexel/s of texture fill rate versus 332.8 GTexel/s for the B50, again roughly a 1.85x difference. Pixel rate is where the gap widens dramatically: the B770 outputs 307.2 GPixel/s, while the B50 manages only 41.60 GPixel/s. That is a 7.4x difference, driven by the B50 having only 16 ROPs compared to 128 ROPs on the B770.

Memory bandwidth follows the same pattern. The B770 uses a 256-bit bus with 512.0 GB/s of bandwidth, while the B50 uses a 128-bit bus with 224.0 GB/s. The B770 has 2.3x the bandwidth, a meaningful margin for high-resolution rendering and texture-heavy workloads. The memory clock also differs: 16 Gbps effective on the B770 versus 14 Gbps effective on the B50.

Clock behavior is the one area where the B50 shows a competitive edge. The B50 has a boost clock of 2600 MHz, which is 200 MHz higher than the B770's 2400 MHz boost. The B50 also has a lower base clock of 1700 MHz versus 2100 MHz on the B770. The higher boost clock on the smaller chip does not compensate for the massive differences in shading units, TMUs, ROPs, and memory bus width.

The recorded benchmark suite contains scores only for the Arc Pro B50, not for the B770. The B50's average benchmark score is 2660, which places it at the 17th percentile of all GPUs in the database. Its nearest rivals in the database include the NVIDIA GeForce GT 1030 at an average score of 2662, a delta of -0.1%, and the NVIDIA Quadro K1100M at 2664, a delta of -0.2%. The B50 also sits close to the NVIDIA GeForce GT 440 (2645, +0.6% for the B50) and the NVIDIA GeForce RTX 5070 SUPER (2690, -1.1% for the B50). This clustering indicates the B50 performs in a very low tier of the overall GPU landscape, despite its modern architecture and 16 GB frame buffer.

Where Each One Wins

The Arc B770 wins in every raw performance category recorded in the database. It has double the shading units (4096 versus 2048), double the TMUs (256 versus 128), eight times the ROPs (128 versus 16), and double the RT cores (32 versus 16). Its FP32 throughput is 19.66 TFLOPS versus 10.65 TFLOPS, and FP16 throughput is 39.32 TFLOPS versus 21.30 TFLOPS. The B770 also carries a wider 256-bit memory bus and nearly double the bandwidth. Any workload that scales with compute units, texture throughput, pixel throughput, or memory bandwidth will favor the B770 by a wide margin.

The Arc Pro B50 wins in the areas of power draw, physical size, and interface flexibility. The B50 has a TDP of 70 W versus 225 W for the B770, and its suggested PSU is 250 W versus 550 W. The B50 requires no external power connectors, while the B770 needs one 6-pin and one 8-pin connector. The B50 also uses a PCIe 5.0 x8 interface, which provides more bandwidth per lane than the B770's PCIe 4.0 x16 connection. The B50 has four mini-DisplayPort 2.1 outputs, while the B770 has one HDMI 2.1a and three DisplayPort 2.1 outputs. The B50 is compact at 167 mm in length, 69 mm in height, and 40 mm in width, while the B770 has no recorded dimensions.

The B50 also has a higher boost clock, 2600 MHz versus 2400 MHz, and a much lower base clock, 1700 MHz versus 2100 MHz. This suggests the B50 is designed to burst to high clocks under light load while maintaining a low idle state, consistent with its professional, low-power positioning. The B770, with its higher base clock and larger silicon, is built for sustained heavy compute.

Specification Differences

The two cards differ in nearly every major specification. The B770 uses the BMG-G31 chip, while the B50 uses the BMG-G21 chip. The B770 has a die size of 368 mm², while the B50's die is 272 mm². The B50 has a recorded transistor count of 19,600 million with a density of 72.1M per mm²; the B770's transistor count and density are not recorded in the database.

Shader resources differ significantly. The B770 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores. The B50 has 2048 shading units, 128 TMUs, 16 ROPs, and 16 RT cores. Clock speeds differ as well: the B770 runs at 2100 MHz base and 2400 MHz boost, while the B50 runs at 1700 MHz base and 2600 MHz boost.

Memory configuration differs in bus width and bandwidth. The B770 uses a 256-bit bus with 512.0 GB/s bandwidth, while the B50 uses a 128-bit bus with 224.0 GB/s bandwidth. Both use 16 GB of GDDR6, but the B770's memory runs at 2000 MHz (16 Gbps effective) versus 1750 MHz (14 Gbps effective) on the B50.

Power and physical specifications diverge sharply. The B770 has a TDP of 225 W, requires a 550 W suggested PSU, and needs one 6-pin and one 8-pin power connector. The B50 has a TDP of 70 W, requires a 250 W suggested PSU, and needs no power connectors. The B770 uses PCIe 4.0 x16, while the B50 uses PCIe 5.0 x8. The B770 has one HDMI 2.1a and three DisplayPort 2.1 outputs; the B50 has four mini-DisplayPort 2.1 outputs. The B50 has recorded dimensions of 167 mm by 69 mm by 40 mm; the B770's dimensions are not recorded.

Architecture Differences

Both cards use the Xe2-HPG architecture, are built on a 5 nm process at TSMC, and support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B770 belongs to the Battlemage generation (Arc 7 series), while the B50 belongs to the Battlemage generation (Pro Series). The B770's predecessor is listed as Alchemist, while the B50 has no recorded predecessor.

The architectural difference in ROP count is the most striking. The B770 has 128 ROPs, while the B50 has only 16 ROPs. This explains the 7.4x difference in pixel rate (307.2 GPixel/s versus 41.60 GPixel/s). The B770's larger die, 368 mm² versus 272 mm², accommodates double the shading units, TMUs, and RT cores. The B50's higher boost clock of 2600 MHz versus 2400 MHz on the B770 suggests a power-optimized design that can reach higher clocks on a smaller chip but cannot sustain the throughput of the larger part.

The B50 is explicitly a professional product with a production status of Active, while the B770 has no production status recorded. The B50's launch MSRP is 349 USD. The B770 has no launch MSRP recorded. The B50's four mini-DisplayPort 2.1 outputs and PCIe 5.0 x8 interface align with professional multi-display and workstation use cases, while the B770's single HDMI and three DisplayPort outputs target consumer display setups.

The Verdict

The data makes the performance hierarchy clear. The Intel Arc B770 is the substantially faster card in every computational and graphics metric recorded. It doubles the FP32 throughput, doubles the texture rate, delivers 7.4x the pixel rate, and provides 2.3x the memory bandwidth of the Arc Pro B50. For any workload that depends on shader compute, texture filtering, pixel output, or memory throughput, the B770 is the correct choice.

The Intel Arc Pro B50 is a different product class entirely. Its average benchmark score of 2660 places it at the 17th percentile of all GPUs, and its nearest rivals are entry-level parts like the NVIDIA GeForce GT 1030 and Quadro K1100M. The B50's 16 GB of memory and four mini-DisplayPort 2.1 outputs make it suitable for multi-display professional setups that do not demand high compute throughput. Its 70 W TDP, lack of external power connectors, and 250 W suggested PSU make it easy to install in compact or power-constrained systems.

The B770 also has a much higher base clock (2100 MHz versus 1700 MHz) and a larger die (368 mm² versus 272 mm²), reinforcing its position as the high-performance part. The B50's higher boost clock (2600 MHz versus 2400 MHz) does not offset the 2x gap in shading units and TMUs, nor the 8x gap in ROPs.

Buyers should select the Arc B770 when raw performance, high pixel throughput, or maximum memory bandwidth is the priority. The Arc Pro B50 should be selected when the priority is low power draw, compact size, no external power connectors, or a professional multi-display output configuration. The recorded data does not support any scenario where the B50 outperforms the B770 in compute or graphics workloads; its advantages are entirely in power, size, and display connectivity.
