Intel Arc G3 Extreme vs NVIDIA B300 SXM6 AC Comparison

Intel Arc G3 Extreme and NVIDIA B300 SXM6 AC represent opposite ends of the computing spectrum, one an integrated graphics solution for portable devices and the other a massive server accelerator module. The data shows a complete mismatch in specifications, performance class, and intended operating environment. The Arc G3 Extreme is an IGP built on Intel's Panther Lake chip, while the B300 SXM6 AC is a dedicated server module with a 1100 W TDP. Their benchmark results, where available, place them in completely different performance percentiles, with the B300 achieving a perfect 100th percentile score while the Arc G3 sits at the 50th percentile. No direct head-to-head benchmark data exists in the database.

Where Each One Wins

The Intel Arc G3 Extreme wins in scenarios where system integration, power efficiency, and portability matter. It uses system shared memory, meaning it requires no dedicated VRAM allocation and draws from the host system's memory pool. Its 80 W TDP and IGP form factor allow it to fit into devices where discrete graphics cards cannot physically or thermally exist. The architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it suitable for consumer graphics workloads on portable devices. Its pixel rate of 60.00 GPixel/s exceeds the B300's 48.77 GPixel/s, indicating superior raw pixel throughput for display-oriented tasks. The Arc G3 also has a higher boost clock ratio, with a 2500 MHz boost compared to the B300's 2032 MHz.

The NVIDIA B300 SXM6 AC wins in compute density and memory capacity. It delivers 76.99 TFLOPS of FP32 performance, exactly 10 times the Arc G3's 7.680 TFLOPS. Its FP16 performance matches its FP32 at 76.99 TFLOPS (1:1), while the Arc G3 achieves 15.36 TFLOPS FP16 at a 2:1 ratio. The B300 features 288 GB of HBM3e memory with 8.19 TB/s bandwidth, a capacity and speed that dwarf any system shared memory configuration. Its 18944 shading units and 592 tensor cores provide massive parallel compute resources. The recorded Geekbench OpenCL score of 369831 places it 7% ahead of the NVIDIA B200, 10.4% ahead of the NVIDIA H200 NVL, 16.3% ahead of the AMD Instinct MI300X, and 25% ahead of the NVIDIA L40S.

Architecture Differences

The process nodes differ significantly. The Arc G3 Extreme uses a 3 nm process fabricated by Intel, while the B300 uses a 5 nm process fabricated by TSMC. The B300's chip, GB110, contains 208,000 million transistors on a 1628 mm² die, yielding a transistor density of 127.8M per mm². The Arc G3's transistor count and die size are listed as unknown in the database. The B300 uses the Blackwell Ultra architecture, while the Arc G3 uses Xe3-LPG. The B300's generation is "Server Blackwell (Bxx)" and the Arc G3 is "Arc Graphics-M (Panther Lake)".

Memory architecture could not be more different. The Arc G3 uses system shared memory with system dependent bandwidth, while the B300 has dedicated 288 GB of HBM3e on an 8192 bit bus delivering 8.19 TB/s. The B300's memory clock runs at 2000 MHz with 8 Gbps effective speed. The Arc G3's memory clock is also listed as "System Shared", indicating it depends entirely on the host system's memory configuration.

The compute resources differ by an order of magnitude. The Arc G3 has 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores. The B300 has 18944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores. The B300 has no listed RT cores, while the Arc G3 has no listed tensor cores. Both have 24 ROPs, resulting in similar pixel processing capability per clock, though the Arc G3's higher boost clock gives it a pixel rate advantage. The B300's texture rate of 1,202.9 GTexel/s is approximately 10 times the Arc G3's 120.0 GTexel/s.

The B300 supports no graphics APIs, listing DirectX, OpenGL, and Vulkan as N/A. It has no display outputs. The Arc G3 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, with display outputs described as "Portable Device Dependent". The B300 uses a PCIe 6.0 x16 bus interface, while the Arc G3 uses an IGP interface. The B300's slot width is "SXM Module" and it requires a 1500 W suggested PSU, while the Arc G3 is an IGP with no power connectors.

Head-to-Head Benchmarks

No direct head-to-head benchmark results are recorded in the database. The only benchmark available is the B300's Geekbench OpenCL score of 369831, which serves as its average benchmark score. The Arc G3 has no recorded benchmark scores and an average benchmark score of 0. The data indicates zero wins for either product in head-to-head comparisons.

The B300's nearest rivals provide context for its performance level. It leads the NVIDIA B200 by 7%, the NVIDIA H200 NVL by 10.4%, the AMD Instinct MI300X by 16.3%, and the NVIDIA L40S by 25%. These deltas place the B300 at the top of the server accelerator hierarchy. The Arc G3's 50th percentile ranking among all GPUs places it in the mid-range of graphics hardware, but with no benchmark scores recorded, its absolute performance cannot be quantified from the database.

The pixel rate comparison shows the Arc G3 ahead at 60.00 GPixel/s versus the B300's 48.77 GPixel/s. The texture rate comparison shows the B300 far ahead at 1,202.9 GTexel/s versus 120.0 GTexel/s. The FP32 compute comparison shows the B300 at 76.99 TFLOPS versus 7.680 TFLOPS, a 10x advantage. The FP16 comparison shows the B300 at 76.99 TFLOPS with 1:1 ratio versus the Arc G3's 15.36 TFLOPS at 2:1 ratio, meaning the B300 has both higher absolute FP16 performance and a more efficient ratio.

The Verdict

The data describes two products with no meaningful overlap in purpose or capability. The Intel Arc G3 Extreme serves as an integrated GPU for portable devices, evidenced by its IGP form factor, system shared memory, portable device dependent display outputs, and 80 W TDP. It provides modern graphics API support and adequate pixel throughput for integrated graphics, with a pixel rate that actually exceeds the B300's.

The NVIDIA B300 SXM6 AC is a server accelerator with no display outputs and no graphics API support. Its 1100 W TDP, 288 GB HBM3e memory, 8.19 TB/s bandwidth, and 76.99 TFLOPS FP32 performance target compute workloads in datacenter environments. Its 100th percentile ranking and 369831 Geekbench OpenCL score confirm its position at the top of the performance hierarchy, leading its nearest rivals by 7% to 25%.

Users requiring a graphics solution for a portable device should select the Arc G3 Extreme based on its integration and API support. Users requiring maximum compute throughput in a server context should select the B300 SXM6 AC based on its 10x FP32 advantage, massive memory subsystem, and top percentile benchmark ranking. The two products do not compete for the same workloads.
