Intel Arc 140V Mobile vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The recorded data for the Intel Arc 140V Mobile and the Intel Arc Pro B65 does not include any direct head-to-head benchmark scores. The database lists no entries in the head-to-head benchmark table, and neither part has an average benchmark score or a list of nearest rivals. The wins count for each product is zero, meaning there are no measured matchups to compare directly.

What the database does provide is a complete set of computed throughput figures for both GPUs. These derived specifications allow a side-by-side comparison of theoretical performance ceilings. The Arc Pro B65 delivers 12.29 TFLOPS of FP32 compute, which is 3.08 times the 3.994 TFLOPS of the Arc 140V Mobile. In FP16 with 2:1 ratio, the Arc Pro B65 reaches 24.58 TFLOPS, compared to 7.987 TFLOPS for the integrated part. That is a large gap in raw arithmetic throughput, and benchmark results would be expected to reflect it in compute-heavy workloads.

Pixel throughput shows a similar pattern. The Arc Pro B65 renders at 192.0 GPixel/s, while the Arc 140V Mobile produces 62.40 GPixel/s. The discrete card is 3.08 times faster in pixel fill. Texture fill rate follows the same ratio: the Arc Pro B65 achieves 384.0 GTexel/s versus 124.8 GTexel/s for the integrated GPU. These numbers scale with the shading unit and texture mapping unit counts, since the Arc Pro B65 has 2560 shading units, 160 TMUs, and 80 ROPs, against 1024 shading units, 64 TMUs, and 32 ROPs for the Arc 140V Mobile.

The memory subsystem creates an even wider separation. The Arc Pro B65 uses 32 GB of GDDR6 on a 256 bit bus, delivering 608.0 GB/s of bandwidth. The Arc 140V Mobile relies on system shared memory, with bandwidth listed as system dependent. No fixed bandwidth figure exists for the integrated part, so a direct numeric comparison is not possible, but the discrete card's dedicated 608.0 GB/s is a fixed resource that does not compete with the CPU for memory access.

Clock behavior also differs. The Arc Pro B65 runs at a flat 2400 MHz base and boost, with no variation between the two. The Arc 140V Mobile spans 300 MHz base to 1950 MHz boost, a wide dynamic range typical of an integrated GPU that idles low and ramps under load. The discrete part trades a higher sustained clock for a 200 W TDP, while the mobile integrated part is rated at 37 W.

The database does not include a percentile ranking beyond the identical 50th percentile value for both GPUs, and neither has an average benchmark score. All comparisons here rely on the recorded specification-derived rates rather than measured application tests. The data indicates no single benchmark victory for either product, because no benchmark data exists in the database for either part.

The Verdict

From the recorded specifications, the Arc Pro B65 is the stronger part by every computed throughput metric. It has 2.5 times the shading units, 2.5 times the TMUs, 2.5 times the ROPs, and 2.5 times the ray tracing cores compared to the Arc 140V Mobile. Its FP32 compute is 3.08 times higher, and its pixel and texture rates are 3.08 times higher. The dedicated 32 GB GDDR6 frame buffer with 608.0 GB/s bandwidth removes any dependence on system memory, which is the Arc 140V Mobile's primary constraint.

The Arc 140V Mobile still holds a meaningful position. It is an integrated GPU with a 37 W TDP, which the data shows is 163 W lower than the Arc Pro B65's 200 W TDP. The power connector field is empty for the integrated part, consistent with an IGP that draws from the platform rather than a separate power input. The Arc Pro B65 requires a 1x 8-pin power connector and a 550 W suggested PSU. Any system built around the Arc Pro B65 must account for that power delivery, while the Arc 140V Mobile needs none.

The Arc 140V Mobile also uses a 3 nm process node from TSMC, versus the 5 nm node for the Arc Pro B65. Transistor counts are unknown for the integrated part, but the Arc Pro B65 is recorded at 19,600 million transistors on a 272 mm² die with a transistor density of 72.1M per mm². The Arc 140V Mobile's die is smaller at 172 mm², but the transistor count is not listed.

Release timing separates the two as well. The Arc 140V Mobile appeared on 2024-09-23, while the Arc Pro B65 has a release date of 2026-03-31. Both are marked as active production products in the database.

Where Each One Wins

The Arc Pro B65 wins in every category where a fixed specification can be compared. Its 2560 shading units and 160 TMUs give it a clear advantage in geometry and texture-heavy rendering. Its 80 ROPs and 192.0 GPixel/s pixel rate make it the stronger choice for high-resolution rasterization. The 20 ray tracing cores double the Arc 140V Mobile's count, and the 608.0 GB/s memory bandwidth ensures the GPU is not starved for data in large scene workloads. The 32 GB GDDR6 capacity allows large datasets or high-resolution textures to reside entirely on the card.

The Arc 140V Mobile's wins are structural rather than performance-based. Its 37 W TDP allows operation in thin-and-light platforms with no external power connector. Its 3 nm TSMC process node is more advanced than the 5 nm node of the Arc Pro B65, which contributes to the lower power envelope. The system shared memory model means the GPU uses whatever memory the host provides, with bandwidth listed as system dependent. In the database, there are no measured benchmark wins for either GPU.

For use cases, the Arc Pro B65 suits a desktop workstation with a dedicated PCIe 5.0 x16 slot and a 550 W suggested PSU. Its four DisplayPort 2.1 outputs support multi-monitor configurations. The Arc 140V Mobile suits a portable platform where the display outputs are portable device dependent and the GPU is integrated into the chip. The Arc Pro B65 is a dual-slot card, while the Arc 140V Mobile is listed as IGP slot width.
