Intel Arc Pro B70 vs NVIDIA GeForce RTX 5080 Mobile Comparison

The Intel Arc Pro B70 and NVIDIA GeForce RTX 5080 Mobile occupy very different positions in the database, yet their raw compute throughput is remarkably close. The Arc Pro B70 is a desktop workstation card with a 230 W TDP, while the RTX 5080 Mobile is an 80 W integrated GPU for laptops. Despite this power disparity, their FP32 performance is nearly identical, which makes the benchmark data particularly telling.

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark runs between these two parts. Instead, the database contains a full suite of measurements for the RTX 5080 Mobile and a percentile ranking for the Arc Pro B70. The Intel part sits at the 50th percentile across all GPUs, while the NVIDIA part reaches the 81st percentile. That gap is significant: it places the RTX 5080 Mobile in the upper fifth of all recorded GPUs, while the Arc Pro B70 lands exactly in the middle of the distribution.

The RTX 5080 Mobile delivers an average benchmark score of 38,349 across its ten recorded tests. Its closest rival in the database is the NVIDIA GeForce MX570, which averages 38,299, a delta of only 0.1%. The RTX 4080 Mobile sits just behind at 38,135, a 0.6% delta. On the other side, the MX570 A averages 38,691, which is 0.9% higher, and the AMD Radeon Pro 580X also averages 38,706, again 0.9% higher. These tight margins suggest the RTX 5080 Mobile's performance profile is well understood, with very little variance between similar parts.

Looking at individual tests, the RTX 5080 Mobile shows its strongest result in Geekbench Vulkan with a score of 169,754, narrowly ahead of its OpenCL result of 166,986. In PassMark G3D, it scores 27,711, which is its second-highest raw score. The compute-oriented PassMark GPU Compute test yields 12,134. The DirectX legacy tests show lower numbers: DirectX 9 scores 314, DirectX 11 scores 253, and DirectX 10 scores 171. The DirectX 12 result is 116, which is the lowest of the group. The G2D test, which measures 2D graphics performance, scores 1,095.

The Arc Pro B70 has no recorded benchmark scores in the database. Its average benchmark score is listed as zero, and its nearest rival list is empty. This means the database holds no direct measurements for the Intel card, only its architectural specifications and its percentile placement. The 50th percentile ranking is the sole performance indicator available, and it suggests the Arc Pro B70 performs at the median level when compared against all GPUs in the database.

The FP32 numbers tell a story of near parity. The Arc Pro B70 delivers 22.94 TFLOPS, while the RTX 5080 Mobile delivers 23.04 TFLOPS. That is a difference of 0.10 TFLOPS, or roughly 0.4%. The RTX 5080 Mobile holds a razor-thin edge in raw single-precision compute. However, the Intel card has a substantially higher pixel rate at 358.4 GPixel/s versus 144.0 GPixel/s for the NVIDIA part. The Intel card also leads in texture rate at 716.8 GTexel/s versus 360.0 GTexel/s. These are large margins: the Arc Pro B70 delivers 2.5 times the pixel throughput and nearly double the texture throughput, despite the FP32 parity.

The Verdict

The data indicates these two GPUs serve fundamentally different purposes. The RTX 5080 Mobile is a laptop part with an 80 W TDP and no power connectors, designed for portable systems. The Arc Pro B70 is a dual-slot desktop card with a 230 W TDP and a single 8-pin connector, requiring a 550 W power supply. The RTX 5080 Mobile carries the higher percentile rank at 81 versus 50, and it has a substantial body of benchmark evidence supporting its performance classification. The Arc Pro B70, by contrast, has no recorded benchmark scores, leaving its percentile ranking as the only comparative data point.

For users who need a mobile GPU with proven performance, the RTX 5080 Mobile is the clear choice based on the database. Its 81st percentile placement and average score of 38,349 place it well above the median. For users who need a desktop workstation card with maximum memory capacity, the Arc Pro B70 offers 32 GB of GDDR6, which is double the RTX 5080 Mobile's 16 GB of GDDR7. The Intel card also delivers far higher pixel and texture rates, which could matter for specific rendering workloads that are fill-rate limited rather than compute limited.

The RTX 5080 Mobile's predecessor is the GeForce 40 Mobile series, and its production status is listed as active. The Arc Pro B70 has no production status listed and no predecessor or successor in the database. The Intel card's release date is March 25, 2026, while the NVIDIA part launched on April 1, 2025, meaning the RTX 5080 Mobile has been available for roughly a year longer in the database's timeline.

Architecture Differences

The two GPUs use different architectures from different generations. The Intel Arc Pro B70 is built on the Xe2-HPG architecture, part of the Battlemage Pro Series, using the BMG-G31 chip. The NVIDIA GeForce RTX 5080 Mobile uses the Blackwell 2.0 architecture, part of the GeForce 50 Mobile series, built on the GB203 chip. Both are fabricated on a 5 nm process at TSMC, so the manufacturing node is identical.

The die sizes are close. The Intel chip measures 368 mm², while the NVIDIA chip measures 378 mm², a difference of 10 mm². However, the transistor counts differ dramatically. The RTX 5080 Mobile contains 45,600 million transistors, giving it a density of 120.6 million per mm². The Arc Pro B70's transistor count is listed as unknown, so no density figure is available for comparison.

The shading unit counts diverge significantly. The RTX 5080 Mobile has 7,680 shading units, while the Arc Pro B70 has 4,096. That is an 87% advantage for the NVIDIA part in raw shader count. The texture mapping units tell a different story: the Intel card has 256 TMUs versus 240 for NVIDIA, a modest 6.7% lead. The render output units also favor Intel, with 128 ROPs versus 96, a 33% advantage. The RT core counts show NVIDIA leading with 60 RT cores versus 32, a 87.5% margin. The tensor core comparison is incomplete because the Arc Pro B70 lists no tensor cores, while the RTX 5080 Mobile has 240.

The clock speeds are reversed in character. The Intel card has a base clock of 2280 MHz and a boost clock of 2800 MHz. The NVIDIA part has a base clock of 975 MHz and a boost clock of 1500 MHz. The Intel card runs at significantly higher frequencies, which helps explain how it achieves comparable FP32 throughput with fewer shading units. The memory clocks also differ: the Arc Pro B70 runs at 2375 MHz with 19 Gbps effective, while the RTX 5080 Mobile runs at 1750 MHz with 28 Gbps effective. The higher effective rate on the NVIDIA part is due to the GDDR7 memory type.

Where Each One Wins

The RTX 5080 Mobile wins in overall performance classification. Its 81st percentile ranking versus 50th, its average benchmark score of 38,349, and its full suite of ten recorded tests all point to a well-characterized, above-median GPU. The Arc Pro B70 has no benchmark scores in the database, so its performance cannot be verified beyond its median percentile placement. The RTX 5080 Mobile also leads in shading units at 7,680 versus 4,096, in RT cores at 60 versus 32, and in memory bandwidth at 896.0 GB/s versus 608.0 GB/s. Its tensor core count of 240 provides AI acceleration hardware that the Intel part does not list.

The Arc Pro B70 wins in memory capacity and fill-rate metrics. Its 32 GB of GDDR6 is double the RTX 5080 Mobile's 16 GB. Its pixel rate of 358.4 GPixel/s is 2.5 times higher than 144.0 GPixel/s, and its texture rate of 716.8 GTexel/s is double the 360.0 GTexel/s. The Intel card also has more ROPs at 128 versus 96 and more TMUs at 256 versus 240. Its higher clock speeds, 2280 MHz base and 2800 MHz boost versus 975 MHz and 1500 MHz, indicate a more aggressively clocked design. The Arc Pro B70 also offers a dual-slot desktop form factor with 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs, while the RTX 5080 Mobile's display outputs are listed as portable device dependent.

For compute workloads that are FP32-bound, the two cards are effectively tied. For workloads that are memory-capacity-bound, the Arc Pro B70 has a clear edge. For workloads that are bandwidth-bound or shader-heavy, the RTX 5080 Mobile leads. For fill-rate-bound workloads, the Arc Pro B70 dominates. The RTX 5080 Mobile is the only one of the two with recorded benchmark data, making it the more verifiable performer in the database.
