Intel Arc Pro B65 vs Intel Graphics 24EU Mobile Comparison

# Head-to-Head Benchmarks

The Intel Arc Pro B65 and Intel Graphics 24EU Mobile occupy opposite ends of Intel's graphics spectrum, and the recorded specifications confirm a massive performance gulf between them. The Arc Pro B65 delivers 12.29 TFLOPS of FP32 compute, while the Graphics 24EU Mobile produces 384.0 GFLOPS. That represents roughly 32 times the raw floating-point throughput, a gap that defines every other comparison in this analysis.

The Arc Pro B65 achieves 192.0 GPixel/s pixel fill rate versus 4.000 GPixel/s for the mobile part, a 48-fold advantage. Texture rate tells a similar story: 384.0 GTexel/s against 12.00 GTexel/s, a 32-fold difference. These are not incremental improvements; they are orders of magnitude that place the two products in entirely different performance classes.

Memory bandwidth separates them even further. The Arc Pro B65 uses 32 GB of GDDR6 on a 256-bit bus, yielding 608.0 GB/s of bandwidth. The Graphics 24EU Mobile relies on System Shared memory with bandwidth listed as System Dependent, meaning it borrows from the host platform's memory subsystem. In practice, the dedicated GDDR6 interface provides a fixed, high-bandwidth path that shared-memory designs cannot match under sustained load.

Clock behavior also diverges sharply. The Arc Pro B65 runs at a flat 2400 MHz for both base and boost, indicating a stable operating point. The Graphics 24EU Mobile scales from 300 MHz base to 1000 MHz boost, a 3.3x range that suggests aggressive power management. The desktop part uses its 200 W TDP to maintain peak clocks continuously, while the 6 W mobile part must ramp dynamically to conserve energy.

Ray tracing hardware exists only on the Arc Pro B65, which carries 20 RT cores. The Graphics 24EU Mobile has no RT cores listed. This is a binary feature difference: one product supports hardware-accelerated ray tracing, the other does not. Similarly, the Arc Pro B65 implements 2560 shading units, 160 TMUs, and 80 ROPs, while the mobile part has 192 shading units, 12 TMUs, and 4 ROPs.

The API support levels differ as well. The Arc Pro B65 reaches DirectX 12 Ultimate (12_2), the highest feature tier, while the Graphics 24EU Mobile tops out at DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, so those APIs are parity points. The DirectX feature level gap matters for games and applications that use mesh shaders, variable rate shading, or other DirectX 12 Ultimate features.

# Where Each One Wins

The Arc Pro B65 wins in every scenario that demands sustained compute throughput. Its 12.29 TFLOPS FP32 performance, 608.0 GB/s memory bandwidth, and 32 GB frame buffer make it suitable for professional rendering, large dataset visualization, and compute-heavy workloads. The 20 RT cores provide hardware ray tracing acceleration, which benefits photorealistic rendering and certain simulation tasks. The 4x DisplayPort 2.1 outputs support multi-monitor professional setups, and the PCIe 5.0 x16 interface offers high host bandwidth for data transfer.

The Graphics 24EU Mobile wins in scenarios where power consumption and physical footprint dominate. Its 6 W TDP is 33 times lower than the Arc Pro B65's 200 W, making it viable for fanless or lightly cooled portable devices. The Ring Bus interface integrates directly into the host processor, eliminating discrete card space requirements. The System Shared memory model allows the GPU to access the full system memory pool, which is flexible for lightweight tasks like video playback, office productivity, and basic 2D acceleration.

The mobile part's 384.0 GFLOPS FP32 throughput remains adequate for entry-level 3D rendering and casual gaming at low resolutions. Its 4.000 GPixel/s pixel rate supports standard desktop compositing without strain. The 768.0 GFLOPS FP16 performance (2:1 ratio) can accelerate certain machine learning inference tasks, though the lack of tensor cores limits dedicated AI acceleration.

The Arc Pro B65's FP16 throughput of 24.58 TFLOPS (2:1) provides substantially more headroom for half-precision compute workloads. Its 19,600 million transistors on a 272 mm² die, built on TSMC's 5 nm process, indicate a complex, dense design. The Graphics 24EU Mobile uses Intel's 10 nm process with unknown transistor count and die size, reflecting its simpler integrated nature.

# The Verdict

The data directs different buyers to different products. The Intel Arc Pro B65 serves users who need dedicated graphics performance: 32 GB of GDDR6 memory, 608.0 GB/s bandwidth, 20 RT cores, and DirectX 12 Ultimate support. It targets professional workstations and high-end desktop builds where 200 W power draw and dual-slot occupancy are acceptable trade-offs.

The Intel Graphics 24EU Mobile serves users who need basic graphics capability inside a low-power mobile platform. Its 6 W TDP, integrated form factor, and shared memory architecture make it suitable for ultra-portable laptops, mini PCs, and embedded systems. The 12_1 DirectX level and lack of RT cores clearly mark it as an entry-level solution.

There is no meaningful overlap between these products. The Arc Pro B65's smallest advantage, pixel rate, still represents a 48x lead. The mobile part's only advantages are power efficiency and integration simplicity. Neither product threatens the other's target market. The Arc Pro B65 is a professional discrete GPU; the Graphics 24EU Mobile is a basic integrated graphics processor. Benchmarks from the database show no recorded head-to-head results, but the specification deltas make the outcome deterministic.

It is fabricated by TSMC on a 5 nm process, containing 19,600 million transistors on a 272 mm² die. The transistor density works out to 72.1M per mm².

The Intel Graphics 24EU Mobile uses the Xe-LP architecture on the Twin Lake chip, part of the HD Graphics-T (Twin Lake) generation. Intel fabricates it on a 10 nm process, with transistor count and die size listed as unknown. This older, simpler architecture targets low-power integrated use rather than high-performance discrete workloads.

The compute topology differs fundamentally. The Arc Pro B65 implements 2560 shading units, 160 texture mapping units, 80 render output units, and 20 ray tracing cores. The Graphics 24EU Mobile implements 192 shading units, 12 TMUs, and 4 ROPs, with no RT cores. The Arc Pro B65's larger execution resources directly explain its pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s, versus 4.000 GPixel/s and 12.00 GTexel/s for the mobile part.

Feature support diverges in modern graphics capabilities. The Arc Pro B65 reaches DirectX 12 Ultimate (12_2), enabling advanced rendering techniques. The Graphics 24EU Mobile stops at DirectX 12 (12_1), missing the highest feature tier. Both support OpenGL 4.6 and Vulkan 1.4, maintaining compatibility with those cross-platform APIs.
