Intel Arc B570 vs Intel Arc B770 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison scenario. The Intel Arc B570 has a full set of benchmark results, while the Intel Arc B770 currently shows no recorded benchmark scores in the database. The head-to-head benchmark array is empty, and the wins counter shows zero for both cards. This means a direct numerical comparison of application performance cannot be established from the current measurements.

What the data does show is the Arc B570's position relative to other GPUs. Its average benchmark score is 20,556. The nearest rival, the NVIDIA GeForce RTX 3070 Mobile, averages 20,534, a difference of just 0.1 percent. The Intel Arc A750 scores 20,582, placing it 0.1 percent ahead of the B570. The NVIDIA Quadro M4000M trails by 0.4 percent with 20,480, and the AMD Radeon R9 M390X sits 0.5 percent behind with 20,662. These deltas are small, indicating the B570 sits in a tightly contested performance band.

The B570's individual scores vary widely by test. In 3DMark Steel Nomad DX12, it records 2,649. Geekbench OpenCL shows 83,514, while Geekbench Vulkan reaches 96,844. Passmark results include 14,195 in G3D, 7,281 in GPU Compute, 661 in G2D, and lower scores in legacy DX tests: 164 in DX9, 118 in DX11, 72 in DX12, and 65 in DX10. The B770 has no comparable figures, so any inference about which card wins specific workloads must come from architectural specifications rather than measured outcomes.

Architecture Differences

Both cards share the same Xe2-HPG architecture and the second-generation Battlemage design, but they are built on different chips. The Arc B570 uses the BMG-G21 die, while the Arc B770 uses the larger BMG-G31 die. Both are fabricated on TSMC's 5 nm process. The B570 packs 19,600 million transistors into a 272 mm² die, yielding a density of 72.1 million transistors per square millimeter. The B770's transistor count is listed as unknown, but its die size is 368 mm², which is 96 mm² larger than the B570's. That physical difference alone suggests a substantially more complex chip.

The shading engine scales accordingly. The B570 has 2,304 shading units, 144 texture mapping units, and 80 render output units. The B770 doubles the shading units to 4,096, raises TMUs to 256, and increases ROPs to 128. Ray tracing cores jump from 18 on the B570 to 32 on the B770. Neither card lists tensor cores in the data, so AI acceleration specifics cannot be compared.

Clock behavior differs meaningfully. The B570 runs at a flat 2,500 MHz for both base and boost. The B770 has a lower base clock of 2,100 MHz but boosts to 2,400 MHz. That is a 100 MHz lower boost ceiling than the B570, yet the B770's larger execution resource pool produces far higher theoretical throughput. The B570 delivers 11.52 TFLOPS FP32 and 23.04 TFLOPS FP16 (2:1). The B770 reaches 19.66 TFLOPS FP32 and 39.32 TFLOPS FP16 (2:1). That is roughly a 70 percent increase in raw compute for the B770.

Pixel and texture rates follow the same pattern. The B570 outputs 200.0 GPixel/s and 360.0 GTexel/s. The B770 outputs 307.2 GPixel/s and 614.4 GTexel/s. Memory architecture also diverges. The B570 uses 10 GB of GDDR6 on a 160-bit bus, with memory clocks at 2,375 MHz (19 Gbps effective) and bandwidth of 380.0 GB/s. The B770 uses 16 GB of GDDR6 on a 256-bit bus, with memory at 2,000 MHz (16 Gbps effective) and bandwidth of 512.0 GB/s. The B770 has 60 percent more capacity and 35 percent more bandwidth, despite slower memory clock speed.

The B770 also changes the PCIe interface. The B570 uses PCIe 4.0 x8, while the B770 uses PCIe 4.0 x16, doubling the host link width. Both cards share identical display outputs: 1x HDMI 2.1a and 3x DisplayPort 2.1. API support is the same as well, with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates two distinct positioning strategies within Intel's Battlemage lineup. The Arc B570 is a fully measured, shipping product with a percentile rank of 65 among all GPUs and an average benchmark score of 20,556. It sits within a fraction of a percent of the RTX 3070 Mobile and the Arc A750, suggesting it lands in a familiar mid-range performance tier. Its smaller chip, 10 GB memory, and x8 PCIe link position it as the more compact and power-conscious option.

The Arc B770 is architecturally dominant on paper. It has nearly twice the shading units, double the ROPs, more ray tracing cores, a wider memory bus, more memory capacity, and higher raw throughput in every compute category. Its percentile rank of 50 is lower than the B570's 65, but that ranking carries no benchmark results behind it, so it may reflect an incomplete database entry rather than actual performance. The B770's 368 mm² die and 225 W TDP indicate a significantly larger and more power-hungry part than the B570's 150 W TDP.

From the recorded data alone, the B770 should outperform the B570 in every measurable category. The specification sheets confirm this for theoretical metrics like FP32 throughput, pixel rate, texture rate, and memory bandwidth. The B570 counters with a higher boost clock and a lower power draw. The B770's launch date is listed as 2025-12-31, which may indicate a future release, while the B570's release date is 2025-01-15. The B570 also has a launch MSRP of 219 USD. The B770 has no launch MSRP listed.

Where Each One Wins

The B570 wins on clock speed. Its boost clock of 2,500 MHz exceeds the B770's 2,400 MHz. It also wins on power efficiency metrics, with a 150 W TDP versus 225 W, a single 8-pin connector versus the B770's 6-pin plus 8-pin setup, and a lower suggested PSU rating of 450 W versus 550 W. The B570 is the only one of the two with recorded benchmark results, so it is the only card with demonstrated performance data in the database. It also has a smaller physical footprint at 272 mm length, while the B770 has no recorded dimensions.

The B770 wins on every raw computational specification. It has 4,096 shading units versus 2,304, 256 TMUs versus 144, 128 ROPs versus 80, and 32 ray tracing cores versus 18. Its FP32 throughput of 19.66 TFLOPS and FP16 throughput of 39.32 TFLOPS dwarf the B570's 11.52 and 23.04 TFLOPS. Pixel rate is 307.2 GPixel/s versus 200.0 GPixel/s, and texture rate is 614.4 GTexel/s versus 360.0 GTexel/s.

The B770 also wins on memory. It has 16 GB versus 10 GB, a 256-bit bus versus 160-bit, and 512.0 GB/s versus 380.0 GB/s. The PCIe interface favors the B770 as well, with x16 versus x8. The B770's die is larger at 368 mm² versus 272 mm², which, along with the higher TDP, indicates it is designed to feed a much larger execution engine. The B570's higher memory clock of 2,375 MHz versus 2,000 MHz does not offset the B770's wider bus and greater capacity.

For use cases implied by the data: the B570 suits configurations where power draw, physical size, and a single power connector matter, and where the host platform only provides PCIe 4.0 x8. The B770 suits workloads that demand higher fill rates, more memory capacity, wider bandwidth, and greater compute throughput. The absence of benchmark data for the B770 means its measured wins remain unverified, but the architectural gap between the two chips is substantial across every theoretical metric.
