Intel Arc B370 vs Intel UHD Graphics 770 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains a single benchmark entry for the Intel Arc B370: 3DMark Steel Nomad DX12, where it scores 1184 points. The Intel UHD Graphics 770 Mobile has no benchmark entries in the database, so direct head-to-head measurements are unavailable. The Arc B370's score places it in the 5th percentile among all GPUs, which indicates its position relative to the broader market rather than against this specific integrated rival.

The nearest rivals for the Arc B370 provide context for its standing. The ATI Mobility Radeon HD 5570 scores 1186, a delta of -0.2% relative to the Arc B370, meaning the Arc B370 trails by a negligible margin. The ATI Radeon HD 5770 scores 1190, a delta of -0.5%. The AMD Radeon HD 7650M scores 1192, a delta of -0.7%. The AMD FirePro M2000 scores 1168, a delta of 1.4%, meaning the Arc B370 leads that part by 1.4%. These deltas are all within roughly 2 percentage points, so the Arc B370's performance cluster is tightly grouped with older discrete mobile and desktop parts.

The UHD Graphics 770 Mobile has an average benchmark score of 0 and no nearest rivals listed. Its 50th percentile placement among all GPUs came from a database with no recorded measurements for it, so no meaningful head-to-head numeric comparison can be constructed from the available data. What can be stated is that the Arc B370's single recorded score is a fixed reference point, while the UHD Graphics 770 Mobile lacks any comparable data point.

Architecture Differences

The two processors come from different Intel generations and architectures. The Arc B370 uses the Panther Lake chip with the Xe3-LPG architecture, belonging to the Arc Graphics-M (Panther Lake) generation. The UHD Graphics 770 Mobile uses the Raptor Lake chip with the Generation 12.2 architecture, belonging to the HD Graphics-M (Raptor Lake) generation.

The process nodes differ substantially. The Arc B370 is built on a 3 nm node at Intel's foundry, while the UHD Graphics 770 Mobile uses a 10 nm node, also at Intel. This process gap affects transistor density and power characteristics, though transistor counts and die sizes are listed as unknown for the Arc B370 and absent for the UHD Graphics 770 Mobile.

The Arc B370 supports DirectX 12 Ultimate (12_2), while the UHD Graphics 770 Mobile supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The Arc B370 includes 10 ray tracing cores; the UHD Graphics 770 Mobile lists no ray tracing cores. The Arc B370 also carries a larger execution resource pool, which is detailed in the specification section.

The bus interface also differs. The Arc B370 uses IGP, and the UHD Graphics 770 Mobile uses Ring Bus. Both are integrated graphics parts with no dedicated slot width beyond IGP, and neither requires power connectors. Display outputs for both are listed as Portable Device Dependent.

Where Each One Wins

The Arc B370 wins on raw compute throughput based on its recorded specifications. Its FP32 performance is 6.144 TFLOPS, which is 7.5 times the UHD Graphics 770 Mobile's 819.2 GFLOPS. Its FP16 performance is 12.29 TFLOPS versus 1.638 TFLOPS, a 7.5x advantage as well. Pixel rate is 48.00 GPixel/s versus 12.80 GPixel/s, a 3.75x lead. Texture rate is 96.00 GTexel/s versus 25.60 GTexel/s, a 3.75x lead.

The UHD Graphics 770 Mobile wins on power draw. Its TDP is 15 W, while the Arc B370 is rated at 25 W. For thermally constrained mobile chassis, the lower power envelope is an advantage. Its boost clock is also lower at 1600 MHz versus 2400 MHz, which contributes to the lower power demand, though it also limits throughput.

The Arc B370's 5th percentile ranking among all GPUs indicates that it sits near the low end of the overall GPU performance distribution. The UHD Graphics 770 Mobile's 50th percentile ranking comes without any benchmark data, so it should not be read as a measured performance claim. The Arc B370's ray tracing support is a functional win, as the UHD Graphics 770 Mobile has no ray tracing cores.

Specification Differences

The two parts differ across nearly every compute metric. The Arc B370 has 1280 shading units, 40 texture mapping units, and 20 raster output units. The UHD Graphics 770 Mobile has 256 shading units, 16 texture mapping units, and 8 raster output units. The Arc B370's shading unit count is 5x higher, its TMU count is 2.5x higher, and its ROP count is 2.5x higher.

Clock speeds: both have a 300 MHz base clock. The Arc B370 boosts to 2400 MHz, while the UHD Graphics 770 Mobile boosts to 1600 MHz. Memory for both is System Shared in size, type, and bus width, with bandwidth listed as System Dependent. Neither has a dedicated memory bus.

Compute rates: the Arc B370 delivers 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 (2:1). The UHD Graphics 770 Mobile delivers 819.2 GFLOPS FP32 and 1.638 TFLOPS FP16 (2:1). Pixel rate: 48.00 GPixel/s versus 12.80 GPixel/s. Texture rate: 96.00 GTexel/s versus 25.60 GTexel/s.

Power and interface: the Arc B370 has a TDP of 25 W; the UHD Graphics 770 Mobile has a TDP of 15 W. The Arc B370 uses an IGP bus interface; the UHD Graphics 770 Mobile uses a Ring Bus interface.

The Verdict

The data indicates a clear compute hierarchy. The Intel Arc B370 outperforms the Intel UHD Graphics 770 Mobile in every measured throughput category: shading units, texture units, raster units, FP32, FP16, pixel rate, and texture rate. Its ray tracing cores add a feature the UHD part cannot match. The Arc B370's DirectX 12 Ultimate support also gives it a newer API feature level.

The UHD Graphics 770 Mobile holds only one recorded advantage: lower power draw at 15 W versus 25 W. For systems where thermal and power budgets are strict, that difference matters. The UHD part also has the older release date of 2023-01-03, and its successor is listed as Arc Graphics-M, which aligns with the Arc B370's generation.

The Arc B370's 5th percentile ranking among all GPUs places it near the low end of the market, but its nearest rivals are older discrete parts like the ATI Radeon HD 5770 and AMD Radeon HD 7650M, and it leads the AMD FirePro M2000 by 1.4%. The UHD Graphics 770 Mobile has no measured benchmark data, so its 50th percentile ranking is not substantiated by recorded scores.

Users who need integrated graphics with modern API support, ray tracing, and higher compute throughput should select the Arc B370. Users who need the lowest power draw in an integrated package should select the UHD Graphics 770 Mobile, accepting its older architecture and lower performance ceiling. The database records no direct benchmark comparison, but the specification differences are decisive on compute and feature support.
