Intel Arc Pro B65 vs NVIDIA GeForce RTX 4080 Max-Q Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between the Intel Arc Pro B65 and the NVIDIA GeForce RTX 4080 Max-Q. Both entries have empty benchmark arrays and zero recorded wins on either side. The percentileVsAllGpus field places both at the 50th percentile, with identical avgBenchmarkScore values of 0. Without measured performance data, the comparison must rely entirely on architectural specifications and recorded feature sets.

The FP32 compute figures show a clear separation. The NVIDIA GeForce RTX 4080 Max-Q delivers 20.04 TFLOPS of FP32 throughput, while the Intel Arc Pro B65 delivers 12.29 TFLOPS. That represents a 63% advantage for the NVIDIA part in raw single-precision compute. The FP16 results differ in approach: NVIDIA maintains a 1:1 ratio at 20.04 TFLOPS, while Intel offers 24.58 TFLOPS at a 2:1 ratio, giving Intel a 23% lead in peak FP16 when the 2:1 mode is active.

Texture and pixel throughput tell a mixed story. The Intel card produces 384.0 GTexel/s against NVIDIA's 313.2 GTexel/s, a 23% advantage for Intel. Pixel rate favors Intel as well, at 192.0 GPixel/s versus 108.0 GPixel/s, a 78% lead. These metrics suggest Intel has a structural advantage in fill-rate-bound workloads, though the compute gap remains substantial.

Memory bandwidth strongly favors Intel. The Arc Pro B65 uses a 256-bit bus with GDDR6 at 19 Gbps effective, yielding 608.0 GB/s. The RTX 4080 Max-Q uses a 192-bit bus with GDDR6 at 18 Gbps effective, yielding 432.0 GB/s. Intel holds a 41% bandwidth advantage. Capacity also differs: 32 GB on the Intel side versus 12 GB on the NVIDIA side.

Architecture Differences

The two GPUs come from different architectural families. Intel uses the Xe2-HPG architecture on the BMG-G21 chip, part of the Battlemage (Pro Series) generation. NVIDIA uses Ada Lovelace on the AD104 chip, part of the GeForce 40 Mobile generation. Both are manufactured by TSMC on a 5 nm process, but the transistor counts diverge sharply.

NVIDIA's AD104 packs 35,800 million transistors on a 294 mm² die, achieving a transistor density of 121.8M / mm². Intel's BMG-G21 contains 19,600 million transistors on a 272 mm² die, with a density of 72.1M / mm². The NVIDIA chip has 83% more transistors and a 68% higher density, reflecting its larger compute footprint.

The shading unit counts reflect this disparity. NVIDIA includes 7424 shading units, 232 texture mapping units, and 80 ROPs. Intel includes 2560 shading units, 160 TMUs, and 80 ROPs. NVIDIA has nearly three times the shading units and 45% more TMUs, while ROP counts match at 80.

Ray tracing and tensor capabilities differ substantially. NVIDIA features 58 RT cores and 232 tensor cores. Intel features 20 RT cores and no tensor cores listed. NVIDIA's tensor core presence enables features not available on the Intel part, though the database does not record specific AI benchmark results.

Clock behavior shows a fundamental design split. Intel operates at a flat 2400 MHz for both base and boost clocks, a static frequency profile. NVIDIA operates at 795 MHz base and 1350 MHz boost, a dynamic range with a 70% boost overhead. The NVIDIA part runs at much lower absolute clocks, consistent with its 60 W TDP.

Power and physical design differ completely. Intel is a dual-slot card with a 200 W TDP, requiring a 1x 8-pin power connector and a 550 W suggested PSU. NVIDIA is an integrated graphics package (IGP) with a 60 W TDP and no power connectors. The NVIDIA part's power draw is 70% lower, and its form factor is not a discrete card at all.

Bus interface and display outputs also diverge. Intel uses PCIe 5.0 x16 with 4x DisplayPort 2.1 outputs. NVIDIA uses PCIe 4.0 x16 with output configuration described as portable device dependent. The Intel card targets fixed workstations with standard display connectivity, while the NVIDIA part targets mobile systems.

API support matches exactly: both list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Release dates differ by about three years: the NVIDIA part appeared on 2023-01-02, while the Intel part followed on 2026-03-31.

The Verdict

The data shows two GPUs engineered for different operating envelopes. The NVIDIA GeForce RTX 4080 Max-Q delivers superior raw compute performance: 20.04 TFLOPS FP32 versus 12.29 TFLOPS, 58 RT cores versus 20, and 232 tensor cores versus none. It also operates at 60 W, which is 140 W lower than Intel's 200 W TDP. For compute-heavy workloads and power-constrained mobile platforms, the NVIDIA part holds the advantage.

The Intel Arc Pro B65 counters with structural advantages in memory and fill rate. Its 608.0 GB/s bandwidth exceeds NVIDIA's by 176 GB/s, and its 32 GB capacity is nearly three times NVIDIA's 12 GB. Pixel rate is 84 GPixel/s higher, and texture rate is 70.8 GTexel/s higher. FP16 peak throughput is 24.58 TFLOPS versus 20.04 TFLOPS. For large memory footprints, high-resolution rendering, and FP16 workloads, the Intel part is the stronger choice.

Neither GPU has recorded benchmark scores in the database, so the verdict rests on specification analysis. The RTX 4080 Max-Q wins on compute density, ray tracing resources, tensor capability, and power efficiency. The Arc Pro B65 wins on memory capacity, memory bandwidth, fill rates, and FP16 throughput. The choice depends on which of these categories matches the target workload.

Where Each One Wins

The NVIDIA GeForce RTX 4080 Max-Q wins in compute-heavy scenarios. Its 20.04 TFLOPS FP32 performance exceeds Intel by 7.75 TFLOPS, and its 58 RT cores provide nearly three times the ray tracing hardware. The 232 tensor cores enable AI-accelerated workloads that the Intel part cannot address. The 60 W TDP makes it suitable for power-constrained mobile platforms, with no external power connectors required.

The Intel Arc Pro B65 wins in memory-bound and fill-rate-bound scenarios. Its 32 GB capacity supports datasets that would exhaust the NVIDIA part's 12 GB. The 608.0 GB/s bandwidth, 192.0 GPixel/s pixel rate, and 384.0 GTexel/s texture rate all exceed the NVIDIA figures. The 24.58 TFLOPS FP16 throughput (2:1) offers a peak compute advantage for FP16 workloads. The 4x DisplayPort 2.1 outputs provide fixed workstation connectivity, while the PCIe 5.0 x16 interface doubles the bus bandwidth of NVIDIA's PCIe 4.0 x16.

For applications requiring maximum single-precision compute, ray tracing density, tensor operations, or minimal power draw, the NVIDIA part is the recorded choice. For applications requiring maximum memory capacity, memory bandwidth, fill rates, FP16 peak performance, or standard display outputs, the Intel part leads. The database shows no overlapping benchmark scores, so these category wins stand as the only recorded basis for selection.
