Intel Arc Pro B70 vs NVIDIA GeForce RTX 5080 Comparison

The Verdict

The database places these two cards in entirely different tiers. The Intel Arc Pro B70 holds a 50th percentile ranking among all GPUs, while the NVIDIA GeForce RTX 5080 sits at the 87th percentile. The RTX 5080 delivers an average benchmark score of 56083, whereas the Arc Pro B70 has no recorded benchmark scores in the database, making direct numerical comparison impossible from the recorded data.

The RTX 5080 is the clear performance leader based on its substantial architectural advantages, with 10752 shading units versus the Intel card's 4096, and a peak FP32 throughput of 56.28 TFLOPS against 22.94 TFLOPS. The RTX 5080 also leads in texture rate, 879.3 GTexel/s versus 716.8 GTexel/s, and in memory bandwidth, 960.0 GB/s versus 608.0 GB/s.

The Intel Arc Pro B70 distinguishes itself through memory capacity and efficiency. It offers 32 GB of GDDR6 memory, double the 16 GB of GDDR7 on the RTX 5080. The Intel card also draws less power, rated at 230 W compared to the RTX 5080's 360 W, and requires a single 8-pin power connector rather than a 16-pin connector. Its suggested power supply is 550 W versus 750 W for the NVIDIA card.

For users requiring maximum frame rates and compute throughput, the data points to the RTX 5080. For workloads that demand large memory capacity or for systems with tighter power constraints, the Arc Pro B70 offers a distinct configuration. The RTX 5080's launch MSRP is 999 USD, while the Arc Pro B70's launch MSRP is 949 USD.

Architecture Differences

The Intel Arc Pro B70 uses the BMG-G31 chip built on the Xe2-HPG architecture, part of the Battlemage Pro Series generation. It is fabricated on a 5 nm process by TSMC with a die size of 368 mm². The card implements 4096 shading units, 256 texture mapping units, 128 raster output units, and 32 ray tracing cores. It does not list tensor cores in the database.

The NVIDIA GeForce RTX 5080 uses the GB203 chip based on Blackwell 2.0 architecture, part of the GeForce 50-series generation. It is also fabricated on a 5 nm process by TSMC but with a slightly larger die at 378 mm². The chip contains 45,600 million transistors with a density of 120.6M per mm². The RTX 5080 packs 10752 shading units, 336 texture mapping units, 112 raster output units, 84 ray tracing cores, and 336 tensor cores.

Memory configurations differ significantly. The Intel card uses 32 GB of GDDR6 on a 256-bit bus, achieving 608.0 GB/s bandwidth with memory clocked at 2375 MHz (19 Gbps effective). The NVIDIA card uses 16 GB of GDDR7 on a 256-bit bus, achieving 960.0 GB/s bandwidth with memory clocked at 1875 MHz (30 Gbps effective). The GDDR7 standard provides the RTX 5080 with 58% more bandwidth despite having half the capacity.

Clock speeds are comparable at the base level: the Arc Pro B70 runs at 2280 MHz base and 2800 MHz boost, while the RTX 5080 runs at 2295 MHz base and 2617 MHz boost. The Intel card has a higher boost clock by 183 MHz, but the NVIDIA card compensates with far more shading units.

Compute precision differs markedly. The Arc Pro B70 delivers 22.94 TFLOPS FP32 and 45.88 TFLOPS FP16 with a 2:1 ratio. The RTX 5080 delivers 56.28 TFLOPS FP32 and 56.28 TFLOPS FP16 with a 1:1 ratio. The NVIDIA card's FP16 performance equals its FP32 performance, a notable advantage for mixed-precision workloads.

Pixel and texture rates favor the RTX 5080 in texture throughput but favor the Intel card in pixel throughput. The Arc Pro B70 achieves 358.4 GPixel/s, while the RTX 5080 achieves 293.1 GPixel/s. Texture rates go the other way: 716.8 GTexel/s for Intel versus 879.3 GTexel/s for NVIDIA.

Both cards support PCIe 5.0 x16, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the Intel card provides 1x HDMI 2.1a and 3x DisplayPort 2.1, while the NVIDIA card provides 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Physical dimensions favor the Intel card in length and height. The Arc Pro B70 measures 267 mm long, 110 mm tall, and 39 mm wide. The RTX 5080 measures 304 mm long, 137 mm tall, and 40 mm wide. Both are dual-slot cards.

Head-to-Head Benchmarks

The database records no head-to-head benchmark entries between the Intel Arc Pro B70 and the NVIDIA GeForce RTX 5080. The Intel card has an empty benchmarks array, an average benchmark score of 0, and no nearest rivals listed. This absence of data means the head-to-head comparison relies entirely on the RTX 5080's recorded scores and the architectural specifications of both cards.

The RTX 5080's benchmark results come from ten tests. In 3DMark Steel Nomad DX12, it scores 8637. Geekbench OpenCL returns 235901, and Geekbench Vulkan returns 255450. PassMark tests show a G3D score of 36565, a GPU compute score of 21789, a G2D score of 1415, and DirectX scores of 208 for DX10, 324 for DX11, 151 for DX12, and 389 for DX9.

The RTX 5080's average benchmark score of 56083 places it close to several AMD rivals. The AMD Radeon 8060S averages 55757, which is 0.6% behind the RTX 5080. The AMD Radeon RX 6750 GRE 12 GB averages 55698, 0.7% behind. The AMD Radeon Pro W5700X averages 54828, 2.3% behind. The AMD Radeon RX 9070 GRE averages 57367, which is 2.2% ahead of the RTX 5080.

Without recorded benchmarks for the Arc Pro B70, the performance gap must be inferred from specifications. The RTX 5080 has 2.6 times the shading units and 2.5 times the FP32 throughput of the Intel card. The NVIDIA card also has 1.6 times the memory bandwidth. These ratios suggest a substantial performance advantage for the RTX 5080 in most compute-bound and graphics-bound tasks.

The Intel card does hold advantages in specific metrics. Its pixel rate of 358.4 GPixel/s exceeds the RTX 5080's 293.1 GPixel/s by 22%. Its boost clock of 2800 MHz exceeds the NVIDIA card's 2617 MHz boost by 183 MHz. Its memory capacity of 32 GB doubles the RTX 5080's 16 GB. These advantages could benefit fill-rate-limited scenarios and memory-heavy workloads.

Where Each One Wins

The NVIDIA GeForce RTX 5080 wins in raw compute throughput. Its 56.28 TFLOPS FP32 nearly doubles the Intel card's 22.94 TFLOPS. Its 10752 shading units provide 2.6 times the shader count. Texture-heavy workloads favor the RTX 5080, which achieves 879.3 GTexel/s versus 716.8 GTexel/s on the Intel card. The NVIDIA card's 84 ray tracing cores versus 32 on Intel makes it the stronger choice for ray-traced content. Its 336 tensor cores give it dedicated AI acceleration hardware, while the Intel card lists no tensor cores.

Memory bandwidth is decisively in the RTX 5080's favor. The GDDR7 implementation delivers 960.0 GB/s, which is 352 GB/s more than the Intel card's GDDR6 bandwidth. This advantage benefits high-resolution textures, large scene complexity, and memory-intensive compute workloads. The RTX 5080's 1:1 FP16 to FP32 ratio also provides balanced precision performance, whereas the Intel card's 2:1 ratio halves its FP16 throughput relative to its FP32 rate.

The Intel Arc Pro B70 wins in memory capacity. Its 32 GB configuration doubles the RTX 5080's 16 GB, which matters for large datasets, massive texture arrays, or multi-application workflows that exceed 16 GB. The Intel card also wins in pixel fill rate, delivering 358.4 GPixel/s versus 293.1 GPixel/s on the RTX 5080. This 22% advantage could benefit rasterization-heavy scenes at high resolutions where pixel throughput becomes the bottleneck.

Power efficiency favors the Intel card. It draws 230 W versus 360 W for the RTX 5080, a 130 W difference. The Intel card also requires a smaller power supply, 550 W suggested versus 750 W, and uses a standard 8-pin connector rather than the 16-pin connector. Its smaller physical footprint, 267 mm length versus 304 mm, makes it easier to fit in compact chassis.

The RTX 5080's benchmark data places it at the 87th percentile among all GPUs, with an average score of 56083. The Arc Pro B70 sits at the 50th percentile with no recorded benchmark scores. The AMD Radeon RX 9070 GRE leads the RTX 5080 by 2.2% in average score, showing that the NVIDIA card faces competition from above, while the other three nearest rivals trail by less than 2.5%.

Release timing differs by roughly 14 months. The RTX 5080 launched on 2025-01-29 with an active production status, while the Arc Pro B70 launched on 2026-03-25. The RTX 5080 lists a predecessor in the GeForce 40 series and a successor in the GeForce 60 series, while the Intel card lists no predecessor or successor in the database.

The RTX 5080's memory runs at 30 Gbps effective, 58% faster than the Intel card's 19 Gbps effective rate. The Intel card's higher boost clock, 2800 MHz versus 2617 MHz, does not compensate for the NVIDIA card's massive shader count advantage. The RTX 5080's 45,600 million transistors on a 378 mm² die, compared to the Intel card's unknown transistor count on a 368 mm² die, reflects a denser implementation.
