Architecture Differences

The Intel Arc G3 Extreme and the NVIDIA B300 represent fundamentally different design philosophies. The Intel part is an integrated graphics processor (IGP) built for portable devices, while the NVIDIA B300 is a dedicated server module. This distinction shapes every aspect of their architecture.

The Intel Arc G3 Extreme uses the Xe3-LPG architecture, part of the Arc Graphics-M generation built around the Panther Lake chip. It is fabricated on a 3 nm process at Intel. The NVIDIA B300 uses the Blackwell Ultra architecture, built on the GB110 chip and fabricated on a 5 nm process at TSMC. The transistor count for the NVIDIA B300 is listed as 104,000 million, while the Intel part's transistor count is unknown.

Memory architecture is sharply divided. The Intel Arc G3 Extreme relies on System Shared memory, with bandwidth described as System Dependent. The NVIDIA B300 features 144 GB of HBM3e memory with a 4096 bit bus width and 4.10 TB/s of bandwidth. The B300's memory clock is listed as 2000 MHz with 8 Gbps effective, while the Intel part's memory clock is simply System Shared.

The compute resources differ in scale. The Intel Arc G3 Extreme has 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores. The NVIDIA B300 has 18944 shading units, 592 TMUs, and 24 ROPs. The NVIDIA part lists 592 tensor cores but does not list RT cores, while the Intel part lists RT cores and no tensor cores.

API support also shows the different target markets. The Intel Arc G3 Extreme supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA B300 lists no DirectX, OpenGL, or Vulkan support, reflecting its server-oriented design with no display outputs. The Intel part's display outputs are described as Portable Device Dependent.

Physical specifications differ as well. The Intel Arc G3 Extreme is an IGP with a slot width of IGP and no power connectors. The NVIDIA B300 is an SXM Module using a PCIe 5.0 x16 bus interface and has no display outputs.

Head-to-Head Benchmarks

The recorded data shows a massive performance gap between these two processors, driven primarily by the difference in scale and power envelope.

The most significant difference appears in FP32 throughput. The NVIDIA B300 delivers 76.99 TFLOPS, while the Intel Arc G3 Extreme delivers 7.680 TFLOPS. The B300 achieves approximately 10 times the FP32 performance of the Intel part. In texture processing, the NVIDIA B300 reaches 1,202.9 GTexel/s, compared to the Intel Arc G3 Extreme's 120.0 GTexel/s, again a roughly 10-fold advantage.

The FP16 comparison is even more lopsided. The NVIDIA B300 delivers 1,231.8 TFLOPS with a 16:1 ratio, while the Intel Arc G3 Extreme delivers 15.36 TFLOPS with a 2:1 ratio. The B300's FP16 output is about 80 times higher, reflecting its tensor core design optimized for AI workloads.

Pixel rate tells a different story. The Intel Arc G3 Extreme achieves 60.00 GPixel/s, while the NVIDIA B300 achieves 48.77 GPixel/s. The Intel part is approximately 23% ahead in pixel throughput despite having the same 24 ROPs. This suggests that the Intel architecture's higher boost clock of 2500 MHz, compared to the B300's 2032 MHz, gives it an edge in this specific metric.

Clock speeds show the Intel part operating at a 300 MHz base clock and 2500 MHz boost clock. The NVIDIA B300 has a 1665 MHz base clock and 2032 MHz boost clock. The Intel part's higher boost clock does not compensate for its far smaller compute configuration.

The power efficiency picture is stark. The NVIDIA B300 consumes 1400 W to deliver its performance, while the Intel Arc G3 Extreme consumes 80 W. The Intel part delivers its 7.680 TFLOPS at 80 W, while the B300 delivers 76.99 TFLOPS at 1400 W. Per watt, the Intel part actually delivers more FP32 throughput, but the absolute performance crown belongs to the NVIDIA part.

Both processors sit at the 50th percentile versus all GPUs in the database, with an average benchmark score of 0, meaning neither has recorded benchmark samples. The head-to-head benchmark array is empty, so the analysis relies entirely on the recorded specification data.

The NVIDIA B300 lists its predecessor as Server Hopper and its successor as Server Rubin. The Intel Arc G3 Extreme has no listed predecessor or successor. Neither product has a launch MSRP recorded. The Intel part has no power connectors because it is an IGP, while the NVIDIA B300's power connector information is not listed.

The Verdict

The data indicates two products designed for entirely different environments with no benchmark overlap. The Intel Arc G3 Extreme is an integrated GPU for portable devices, drawing 80 W and using system shared memory. The NVIDIA B300 is a server module drawing 1400 W with 144 GB of dedicated HBM3e memory.

For FP32 and FP16 compute workloads, the NVIDIA B300 is the clear choice. Its 76.99 TFLOPS FP32 output is roughly 10 times the Intel Arc G3 Extreme's 7.680 TFLOPS. Its FP16 output of 1,231.8 TFLOPS dwarfs the Intel part's 15.36 TFLOPS by a factor of about 80. Texture rate follows the same pattern, with the B300 at 1,202.9 GTexel/s versus 120.0 GTexel/s for the Intel part.

For pixel throughput, the Intel Arc G3 Extreme holds the advantage at 60.00 GPixel/s versus the NVIDIA B300's 48.77 GPixel/s. This is the only performance metric where the Intel part leads, and it comes from the Intel part's higher boost clock of 2500 MHz.

The Intel Arc G3 Extreme suits systems requiring integrated graphics with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. Its 12 RT cores provide ray tracing capability in a low-power IGP package. The NVIDIA B300 has no display outputs and no graphics API support listed, confirming its role as a compute accelerator rather than a graphics solution.

The NVIDIA B300 targets server deployments needing maximum FP32 and FP16 throughput, with tensor cores for AI workloads and a suggested 1800 W power supply. The Intel Arc G3 Extreme targets portable devices needing modest graphics performance within an 80 W envelope.

The percentile ranking places both at 50, and the average benchmark score is 0 for both, indicating no recorded benchmark samples in the database. The specification data alone shows that these products do not compete in the same market segment, and the choice between them depends entirely on the deployment context: portable integrated graphics versus server compute acceleration.
