Intel Arc 130V Mobile vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the Intel Arc 130V Mobile and the Intel Arc Pro B65. Both cards have an empty benchmark array, an average benchmark score of zero, and no nearest rival data. Consequently, there are no measured wins, no percentile deltas, and no performance margins to report between these two parts.

The absence of direct measurements is significant in itself. The Intel Arc 130V Mobile sits at the 50th percentile among all GPUs in the database, and the Intel Arc Pro B65 also sits at the 50th percentile. Identical percentiles indicate that, in the absence of direct comparison data, the database places both products at the median of the overall GPU distribution. That does not mean they perform alike; it means the database has no recorded evidence to separate them yet.

Without benchmark scores, the only quantitative performance indicators available are the theoretical throughput figures from each card's specification sheet. The Intel Arc Pro B65 delivers 12.29 TFLOPS of FP32 compute, while the Intel Arc 130V Mobile delivers 3.315 TFLOPS. That is a 3.7x difference in raw single-precision throughput. The Pro B65 also produces 384.0 GTexel/s of texture fill rate versus 103.6 GTexel/s for the 130V Mobile, a 3.7x margin. Pixel throughput favors the Pro B65 as well: 192.0 GPixel/s versus 51.80 GPixel/s, again a 3.7x gap. These are architectural peak rates, not application benchmarks, so real-world deltas may differ, but the recorded data indicates a consistent three-to-four-fold advantage for the Pro B65 across every throughput metric.

The FP16 figures follow the same pattern. The Pro B65 reaches 24.58 TFLOPS with a 2:1 ratio, while the 130V Mobile reaches 6.630 TFLOPS with the same 2:1 ratio. The proportional gap remains at roughly 3.7x. No game-specific or synthetic benchmark data exists in the database to refine these numbers further.

Architecture Differences

The two GPUs use different Xe2 variants. The Intel Arc 130V Mobile is built on the Lunar Lake chip and uses the Xe2-LPG architecture, which is the low-power graphics variant aimed at integrated use. The Intel Arc Pro B65 is built on the BMG-G21 chip and uses the Xe2-HPG architecture, the high-performance discrete variant from the Battlemage Pro Series. The manufacturing nodes differ: the 130V Mobile uses a 3 nm process at TSMC, while the Pro B65 uses a 5 nm process, also at TSMC. The 130V Mobile's die size is 172 mm², while the Pro B65's die is 272 mm². Transistor counts are listed as unknown for the 130V Mobile, but the Pro B65 carries 19,600 million transistors at a density of 72.1M per mm².

Compute resources diverge sharply. The 130V Mobile has 896 shading units, 56 texture mapping units, 28 raster operation units, and 7 ray tracing cores. The Pro B65 has 2560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores. In each category, the Pro B65 has roughly 2.9x the units of the 130V Mobile. Neither card lists tensor cores in the database.

Clock behavior also differs. The 130V Mobile runs at a 300 MHz base clock and boosts to 1850 MHz. The Pro B65 runs at a flat 2400 MHz base and boost, meaning no dynamic boost range is recorded. The Pro B65's higher clock, combined with its larger unit counts, drives its throughput advantage.

Memory architecture is fundamentally different. The 130V Mobile uses system shared memory, with a system dependent bus width and bandwidth, and its memory clock is listed as "System Shared." The Pro B65 uses 32 GB of dedicated GDDR6 memory on a 256 bit bus, with a memory clock of 2375 MHz (19 Gbps effective) and a bandwidth of 608.0 GB/s. The 130V Mobile has no dedicated memory pool at all, so its memory performance depends entirely on the host platform.

Power and physical design separate the two as well. The 130V Mobile is an integrated graphics processor with a 37 W TDP and an IGP slot width, meaning it has no power connectors and no suggested PSU. The Pro B65 is a dual-slot discrete card with a 200 W TDP, a single 8-pin power connector, and a suggested 550 W PSU. The Pro B65 connects via PCIe 5.0 x16, while the 130V Mobile uses an IGP bus interface. Display outputs reflect the same split: the 130V Mobile's outputs are portable device dependent, while the Pro B65 provides 4x DisplayPort 2.1.

API support is identical on paper. Both cards list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. No other API differences are recorded.

The Verdict

The data supports a clear separation based on use case. The Intel Arc Pro B65 is the only one of the two with discrete memory, a 608.0 GB/s bandwidth figure, and 32 GB of GDDR6. It also delivers 12.29 TFLOPS of FP32 compute, 384.0 GTexel/s texture fill, and 192.0 GPixel/s pixel fill. The Intel Arc 130V Mobile, by contrast, relies on system shared memory with system dependent bandwidth, offers 3.315 TFLOPS of FP32 compute, and draws only 37 W.

For workloads that fit within an integrated power envelope, the 130V Mobile has the advantage of being an IGP with no external power connector and no separate slot occupancy. For workloads that need sustained throughput, dedicated memory, or high-bandwidth access, the Pro B65 is the only part in this comparison with the recorded specifications to support them. The Pro B65's 200 W TDP and 550 W suggested PSU indicate a desktop workstation orientation, while the 130V Mobile's 37 W TDP and portable device dependent outputs indicate a mobile integrated orientation.

There is no benchmark data in the database to confirm how these theoretical figures translate into application performance. The recorded specifications, however, point to the Pro B65 as the higher-throughput part across every measured compute, texture, and pixel rate, with the 130V Mobile offering a dramatically lower power draw and integrated form factor.

Where Each One Wins

The Intel Arc Pro B65 wins on every recorded throughput specification. Its FP32 rate of 12.29 TFLOPS is 3.7x the 130V Mobile's 3.315 TFLOPS. Its texture rate of 384.0 GTexel/s is 3.7x the 130V Mobile's 103.6 GTexel/s. Its pixel rate of 192.0 GPixel/s is 3.7x the 130V Mobile's 51.80 GPixel/s. Its FP16 rate of 24.58 TFLOPS is 3.7x the 130V Mobile's 6.630 TFLOPS. It also has 20 ray tracing cores versus 7, 160 TMUs versus 56, and 80 ROPs versus 28.

The Pro B65 also wins on memory. It has 32 GB of dedicated GDDR6 with 608.0 GB/s of bandwidth, while the 130V Mobile has no dedicated memory and a system dependent bandwidth figure. The Pro B65's memory clock is 2375 MHz (19 Gbps effective), while the 130V Mobile's memory clock is listed as system shared. For any workload that depends on memory bandwidth, the Pro B65's 608.0 GB/s is the only quantified bandwidth in this comparison.

The Intel Arc 130V Mobile wins on power and integration. Its 37 W TDP is far below the Pro B65's 200 W TDP. It has an IGP slot width, no power connectors, and no suggested PSU, while the Pro B65 is a dual-slot card requiring a single 8-pin connector and a 550 W suggested PSU. The 130V Mobile's 3 nm process node is smaller than the Pro B65's 5 nm node, and its die size of 172 mm² is smaller than the Pro B65's 272 mm². These factors make the 130V Mobile suitable for portable, integrated environments, whereas the Pro B65 is a discrete, dual-slot component.

The 130V Mobile also has the earlier release date, with the database listing 2024-09-23 for the 130V Mobile and 2026-03-31 for the Pro B65. The 130V Mobile's predecessor is listed as HD Graphics-M, while the Pro B65 has no predecessor recorded.
