Intel Arc B770 vs NVIDIA GeForce RTX 5070 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results for the Intel Arc B770 and the NVIDIA GeForce RTX 5070. The Intel Arc B770 has no benchmark scores listed in the database, while the NVIDIA GeForce RTX 5070 has a full suite of recorded measurements. This absence of comparative data means the analysis must rely on the architectural specifications and the RTX 5070's standalone performance figures.

The RTX 5070 delivers a 3DMark Steel Nomad DX12 score of 5077. In OpenCL workloads, it records 172660 points, while its Vulkan result reaches 178923 points. The PassMark suite shows a G3D score of 29137, a GPU compute score of 15787, and legacy DirectX results of 320 for DirectX 9, 277 for DirectX 11, 180 for DirectX 10, and 108 for DirectX 12. The 2D graphics score sits at 1305. Its average benchmark score across all recorded tests is 40377, placing it in the 82nd percentile of all GPUs in the database.

The RTX 5070's nearest rivals in the database are all professional workstation cards, with the AMD Radeon Pro 580 scoring 40318 (0.1% ahead), the AMD Radeon Pro 5300 scoring 40870 (1.2% ahead), the AMD Radeon Pro WX 7100 scoring 40063 (0.8% behind), and the NVIDIA RTX A500 Mobile scoring 39568 (2.0% behind). This clustering suggests the RTX 5070's average score sits in a narrow band of workstation-class performance, with no consumer GPU rivals recorded nearby.

The Intel Arc B770 shows zero benchmark entries, zero wins in any comparative test, and a 50th percentile ranking with an average score of zero. The database records no measurable performance data for this card, which prevents any quantitative comparison between the two.

Architecture Differences

The Intel Arc B770 uses the BMG-G31 chip built on the Xe2-HPG architecture, belonging to the Battlemage generation within the Arc 7 family. The NVIDIA GeForce RTX 5070 uses the GB205 chip based on Blackwell 2.0, part of the GeForce 50 series. Both are manufactured on a 5 nm process at TSMC, but the die characteristics differ substantially. The Arc B770 measures 368 mm² with an unspecified transistor count, while the RTX 5070 measures 263 mm² and contains 31,100 million transistors, giving it a transistor density of 118.3M per mm².

The Arc B770 packs 4096 shading units, 256 texture mapping units, and 128 raster output units. It includes 32 ray tracing cores and no tensor cores in the recorded data. The RTX 5070 uses 6144 shading units, 192 TMUs, and 80 ROPs, with 48 ray tracing cores and 192 tensor cores. The shading unit advantage of the RTX 5070 (6144 versus 4096) is counterbalanced by the Arc B770's larger TMU and ROP counts.

Clock behavior differs as well. The Arc B770 runs a 2100 MHz base clock and 2400 MHz boost clock. The RTX 5070 runs higher at 2325 MHz base and 2512 MHz boost. The compute throughput reflects these differences: the Arc B770 delivers 19.66 TFLOPS FP32 and 39.32 TFLOPS FP16 (at a 2:1 ratio), while the RTX 5070 delivers 30.87 TFLOPS FP32 and 30.87 TFLOPS FP16 (at a 1:1 ratio). The RTX 5070's FP32 output is roughly 57% higher than the Arc B770's.

Memory configurations diverge sharply. The Arc B770 uses 16 GB of GDDR6 on a 256-bit bus, yielding 512.0 GB/s of bandwidth. The RTX 5070 uses 12 GB of GDDR7 on a 192-bit bus, yielding 672.0 GB/s of bandwidth. The RTX 5070 has 31% more bandwidth despite a narrower bus, thanks to faster memory running at 1750 MHz with 28 Gbps effective transfer. The Arc B770's memory runs at 2000 MHz with 16 Gbps effective. The Arc B770's larger frame buffer of 16 GB contrasts with the RTX 5070's 12 GB.

Pixel and texture rates also differ. The Arc B770 achieves 307.2 GPixel/s and 614.4 GTexel/s. The RTX 5070 achieves 201.0 GPixel/s and 482.3 GTexel/s. The Arc B770 leads in both rasterization throughput metrics, despite the RTX 5070's higher compute and shading counts.

Power requirements show the RTX 5070 consuming 250 W TDP with a 600 W suggested PSU, while the Arc B770 draws 225 W TDP with a 550 W suggested PSU. Both are dual-slot cards, but the Arc B770 uses a 1x 6-pin plus 1x 8-pin power connector configuration, while the RTX 5070 uses a single 16-pin connector. The RTX 5070 lists physical dimensions of 245 mm length, 115 mm height, and 40 mm width; the Arc B770 has no recorded dimensions.

The RTX 5070 connects via PCIe 5.0 x16, while the Arc B770 uses PCIe 4.0 x16. Display outputs are similar in count: the Arc B770 offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the RTX 5070 offers 1x HDMI 2.1b and 3x DisplayPort 2.1b. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The RTX 5070 wins in raw compute throughput. Its FP32 output of 30.87 TFLOPS exceeds the Arc B770's 19.66 TFLOPS. It also leads in memory bandwidth with 672.0 GB/s versus 512.0 GB/s, in shading units with 6144 versus 4096, in ray tracing cores with 48 versus 32, and in tensor cores with 192 versus none recorded. The RTX 5070 also carries a higher base and boost clock, a newer PCIe 5.0 interface, and a higher 82nd percentile ranking with a recorded average benchmark score of 40377.

The Arc B770 wins in memory capacity with 16 GB versus 12 GB. It also leads in rasterization throughput, achieving 307.2 GPixel/s against the RTX 5070's 201.0 GPixel/s, and 614.4 GTexel/s against 482.3 GTexel/s. The Arc B770 has more TMUs (256 versus 192) and more ROPs (128 versus 80). Its FP16 output of 39.32 TFLOPS exceeds the RTX 5070's 30.87 TFLOPS, though the Arc B770 achieves this at a 2:1 ratio while the RTX 5070 runs 1:1. The Arc B770 also has a lower TDP at 225 W versus 250 W and a lower suggested PSU of 550 W versus 600 W.

The Arc B770's larger die of 368 mm² contrasts with the RTX 5070's 263 mm², but the RTX 5070 packs far more transistors into that smaller area.

The Verdict

The data indicates a clear divide between the two GPUs. The NVIDIA GeForce RTX 5070 is the only one of the two with recorded benchmark results, and its average score of 40377 places it in the 82nd percentile of all GPUs. It delivers higher FP32 compute, more bandwidth, more shading units, more ray tracing cores, and a dedicated tensor core array. Its release date of 2025-03-03 and active production status confirm it as a current product.

The Intel Arc B770 presents a different set of strengths. Its 16 GB frame buffer doubles as a capacity advantage over the RTX 5070's 12 GB. Its pixel rate of 307.2 GPixel/s and texture rate of 614.4 GTexel/s indicate stronger fill-rate performance, and its 256 TMUs and 128 ROPs support that interpretation. The 225 W TDP makes it the lower-power option.

For scenarios where compute throughput, ray tracing, bandwidth, and proven benchmark results matter, the RTX 5070 is the data-backed choice. For workloads that favor larger memory capacity or higher fill rates, the Arc B770's specifications point to those strengths, but the absence of any recorded benchmark scores for the Intel card leaves its real-world performance unverified in the database. The RTX 5070's 82nd percentile standing, supported by ten separate benchmark entries, gives it the only measurable performance evidence available.
