Where Each One Wins

The Intel Arc Graphics 128EU Mobile wins in situations where low power draw and integrated graphics are required. Its 28 W TDP makes it suitable for portable devices, and its output is described as "Portable Device Dependent," meaning it is designed to drive displays on laptops or other mobile hardware. The Arc also supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, making it a functional option for consumer graphics workloads on the go.

The NVIDIA B300 SXM6 AC wins in every raw performance category recorded in the database. It delivers 76.99 TFLOPS of FP32 compute versus the Arc's 4.608 TFLOPS, a 16.7x advantage. Its texture rate of 1,202.9 GTexel/s dwarfs the Arc's 144.0 GTexel/s. The B300 is a server module with no display outputs, designed exclusively for compute acceleration in data centers. Its 1100 W TDP and suggested 1500 W PSU indicate a machine designed for maximum throughput, not efficiency.

The B300 also wins decisively in memory capacity and bandwidth. With 288 GB of HBM3e and 8.19 TB/s bandwidth, it can hold and process massive datasets far beyond what any system-shared memory solution can manage. The Arc's memory performance is "System Dependent," meaning it varies with the host laptop's RAM speed and architecture.

Architecture Differences

The Intel Arc Graphics 128EU Mobile is built on the Xe-LPG architecture, part of the Meteor Lake chip. It uses a 10 nm process at Intel's own foundry. The GPU integrates 1024 shading units, 64 texture mapping units, and 32 raster output units. It has no dedicated tensor cores or RT cores listed in the database. The Arc is an IGP (integrated graphics processor) with a Ring Bus interface, meaning it shares the system's memory and power envelope.

The NVIDIA B300 SXM6 AC is built on the Blackwell Ultra architecture, using the GB110 chip on a 5 nm TSMC process. The database lists 208,000 million transistors on a 1628 mm² die, yielding a transistor density of 127.8M per mm². This is a massive, dedicated accelerator with 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores. The B300 uses a PCIe 6.0 x16 bus interface and is packaged as an SXM Module.

The architectural philosophies differ sharply. Intel's Xe-LPG is a low-power, integrated solution designed to coexist with a CPU in a mobile package. NVIDIA's Blackwell Ultra is a high-power, discrete server accelerator with tensor cores for AI workloads. The B300 has no display outputs, while the Arc's outputs are tied to the portable device it is embedded in.

The B300's FP16 performance is 76.99 TFLOPS at 1:1 ratio, meaning it does not double FP16 throughput relative to FP32. The Arc's FP16 is 9.216 TFLOPS at 2:1 ratio, meaning it doubles FP16 throughput compared to its FP32 rate. This indicates the Arc has some consumer-oriented FP16 acceleration, while the B300 treats FP16 as a first-class citizen with equal throughput to FP32.

Specification Differences

The two products differ in nearly every recorded specification. The process node: Intel uses 10 nm, NVIDIA uses 5 nm. The foundry: Intel is self-foundry, NVIDIA uses TSMC. The transistor count: the B300 has 208,000 million, while the Arc has no recorded transistor count. The die size: the B300 is 1628 mm², the Arc has no recorded die size.

Clock speeds: the Arc has a 300 MHz base and 2250 MHz boost. The B300 has a 1665 MHz base and 2032 MHz boost. The Arc's base clock is drastically lower, but its boost clock is higher. Memory: the Arc uses system shared memory with no dedicated size or bus width, while the B300 uses 288 GB HBM3e on an 8192-bit bus.

Compute resources: the Arc has 1024 shading units, 64 TMUs, and 32 ROPs. The B300 has 18,944 shading units, 592 TMUs, and 24 ROPs. The B300 has 592 tensor cores; the Arc has none listed. The Arc has no RT cores listed; the B300 also has no RT cores listed.

Pixel rate: the Arc delivers 72.00 GPixel/s, while the B300 delivers 48.77 GPixel/s. This is one of the few metrics where the Arc leads, due to its higher ROP count and boost clock. Texture rate: the Arc delivers 144.0 GTexel/s, while the B300 delivers 1,202.9 GTexel/s. FP32: the Arc delivers 4.608 TFLOPS, the B300 delivers 76.99 TFLOPS. FP16: the Arc delivers 9.216 TFLOPS (2:1), the B300 delivers 76.99 TFLOPS (1:1).

API support: the Arc supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The B300 has no API support listed (N/A for all three). Display outputs: the Arc is "Portable Device Dependent," the B300 has no outputs. Release dates: the Arc launched on 2023-12-13, the B300 on 2025-09-10. Production status: both are Active.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Arc Graphics 128EU Mobile and the NVIDIA B300 SXM6 AC. The wins counter shows 0 for both sides. However, the B300 has a recorded Geekbench OpenCL score of 369,831, while the Arc has no benchmark scores at all.

The B300's nearest rivals provide context for its performance. The NVIDIA B200 scores 345,482, which is 7% lower than the B300. The NVIDIA H200 NVL scores 334,891, 10.4% lower. The AMD Instinct MI300X scores 317,994, 16.3% lower. The NVIDIA L40S scores 295,763, 25% lower. These deltas show the B300 sits at the top of the database's server GPU hierarchy.

The Arc's 50th percentile ranking places it in the middle of all GPUs, but without any benchmark scores, its actual performance cannot be quantified in the database. The B300's 100th percentile ranking confirms it is the fastest recorded GPU.

The FP32 compute gap is the most striking single-number comparison. The B300's 76.99 TFLOPS is approximately 16.7 times the Arc's 4.608 TFLOPS. The texture rate gap is even larger: 1,202.9 GTexel/s versus 144.0 GTexel/s, an 8.35x difference. The shading unit count difference is 18,944 versus 1,024, an 18.5x difference.

The memory bandwidth difference is absolute. The B300 has 8.19 TB/s of dedicated HBM3e bandwidth, while the Arc depends on system shared memory with bandwidth described as "System Dependent." In practice, this means the B300 can feed its compute units at full speed, while the Arc is constrained by the host laptop's memory subsystem.

The Arc does win in pixel rate: 72.00 GPixel/s versus 48.77 GPixel/s. This is because the Arc has 32 ROPs versus the B300's 24 ROPs, and the Arc's higher boost clock of 2250 MHz helps. This suggests the Arc may be relatively stronger at traditional rasterization output, though its absolute compute power is far lower.

The Verdict

The data indicates these are products for entirely different purposes. The Intel Arc Graphics 128EU Mobile is an integrated GPU for Meteor Lake laptops. Its 28 W TDP, system shared memory, and portable device dependent outputs define it as a mobile consumer part. Its 50th percentile ranking and support for DirectX 12, OpenGL 4.6, and Vulkan 1.4 make it suitable for mainstream laptop graphics. The higher pixel rate, 72.00 GPixel/s, and boost clock of 2250 MHz show it can handle display output tasks competently within its power envelope.

The NVIDIA B300 SXM6 AC is a server accelerator for AI and compute workloads. Its 1100 W TDP, SXM Module form factor, and no display outputs confirm it is not a consumer product. The 288 GB HBM3e memory and 8.19 TB/s bandwidth are designed for large model inference and training. The 592 tensor cores and 76.99 TFLOPS FP16 throughput at 1:1 ratio indicate a machine built for neural network workloads. Its 100th percentile ranking and leadership over the B200, H200 NVL, MI300X, and L40S show it is the fastest GPU in the database.

The choice between them is not a choice at all for most users. The Arc is the only option for a Meteor Lake laptop's integrated graphics. The B300 is the only option for a data center seeking top-tier compute density. The Arc cannot approach the B300's compute, memory, or bandwidth. The B300 cannot function in a portable device, requiring 1500 W PSU and having no display outputs.

A builder selecting hardware for a mobile workstation should use the Arc. A data center operator deploying AI infrastructure should use the B300. The database records no direct comparison between them, and none is needed. Their specifications place them at opposite ends of the GPU spectrum: one for efficiency and portability, the other for raw throughput and scale.
