AMD Radeon 760M vs NVIDIA B300 SXM6 AC Comparison

Head-to-Head Benchmarks

The recorded data contains one directly comparable benchmark between the AMD Radeon 760M and the NVIDIA B300 SXM6 AC: Geekbench OpenCL. This single measurement is decisive. The NVIDIA B300 SXM6 AC scores 369,831, while the AMD Radeon 760M scores 20,255. The delta is -94.5% from the perspective of the AMD part, meaning the NVIDIA accelerator delivers roughly 18 times the OpenCL performance of the integrated Radeon. This is not a marginal gap; it is a categorical difference in compute capability.

The B300 SXM6 AC’s score places it in the 100th percentile of all GPUs in the database. Its nearest rivals reinforce its standing. The NVIDIA B200 averages 345,482, which is 7% behind. The NVIDIA H200 NVL averages 334,891, a 10.4% deficit. The AMD Instinct MI300X scores 317,994 on average, trailing by 16.3%. The NVIDIA L40S averages 295,763, which is 25% lower. Every one of these alternatives is a high-end data center part, and the B300 SXM6 AC sits above all of them in the recorded OpenCL data.

The AMD Radeon 760M, by contrast, sits at the 35th percentile of all GPUs. Its average benchmark score across all recorded tests is 6,019. Its nearest rivals are clustered tightly around that figure. The AMD Radeon RX 6400 averages 6,001, a 0.3% difference. The NVIDIA GeForce GTX 770M also averages 6,000, again a 0.3% delta. The NVIDIA RTX PRO 6000 Blackwell Server averages 5,996, 0.4% lower. The NVIDIA Quadro P2000 averages 6,049, which is 0.5% higher. This cluster indicates that the Radeon 760M performs in a narrow band around the 6,000-point average, with no rival in its immediate vicinity exceeding a half-percent gap. The B300 SXM6 AC, in contrast, has no rival within 7% of its score.

The other benchmark entries for the Radeon 760M show its profile across different workloads. In 3DMark Steel Nomad DX12, it scores 400. Passmark results include DirectX 10 at 19, DirectX 11 at 52, DirectX 12 at 25, and DirectX 9 at 65. The G2D score is 890, the G3D score is 5,310, and the GPU compute score is 2,840. Geekbench Vulkan yields 30,336. These figures collectively describe an integrated graphics solution that handles light to moderate tasks but does not approach the compute throughput of a dedicated server accelerator. The B300 SXM6 AC has only the one recorded OpenCL benchmark, but that single data point is sufficient to establish its position at the top of the database.

Architecture Differences

The two products are built for entirely different segments, and their architectural parameters reflect that divergence. The AMD Radeon 760M uses the Phoenix chip with RDNA 3.0 architecture, part of the Navi III IGP generation. It is fabricated on a 4 nm process at TSMC, with 25,390 million transistors on a 178 mm² die. The transistor density is 142.6 million per square millimeter. The NVIDIA B300 SXM6 AC uses the GB110 chip with Blackwell Ultra architecture, part of the Server Blackwell generation. It is also made by TSMC, but on a 5 nm process. The B300 packs 208,000 million transistors on a 1,628 mm² die, yielding a lower density of 127.8 million per square millimeter. The die size difference is enormous, and the transistor count is roughly eight times higher on the NVIDIA part.

Compute resources differ sharply. The Radeon 760M has 512 shading units, 32 texture mapping units, and 16 raster output units. It includes 8 ray tracing cores but no dedicated tensor cores. The B300 SXM6 AC has 18,944 shading units, 592 TMUs, and 24 ROPs. It has 592 tensor cores and no separately listed ray tracing cores. The raw throughput numbers confirm the scale: the Radeon 760M produces 41.58 GPixel/s pixel rate and 83.17 GTexel/s texture rate, with 5.323 TFLOPS FP32 and the same 5.323 TFLOPS FP16. The B300 SXM6 AC delivers 48.77 GPixel/s and 1,202.9 GTexel/s, with 76.99 TFLOPS FP32 and 76.99 TFLOPS FP16. The texture rate difference is especially stark, a factor of roughly 14.

Memory systems are fundamentally different. The Radeon 760M uses system shared memory, with system-dependent bandwidth and no dedicated VRAM. The B300 SXM6 AC has 288 GB of HBM3e on an 8,192-bit bus, with 8.19 TB/s of bandwidth. The memory clock is listed as 2000 MHz with 8 Gbps effective. Clock speeds also differ: the Radeon runs at 800 MHz base and 2,599 MHz boost, while the B300 runs at 1,665 MHz base and 2,032 MHz boost. The Radeon’s boost clock is higher, but that does not compensate for the massive difference in execution resources.

Power and physical specifications separate the two further. The Radeon 760M has a TDP of 15 W, is an integrated GPU (IGP) with no power connectors, and uses a PCIe 4.0 x8 interface. The B300 SXM6 AC has a TDP of 1,100 W, is an SXM module, and uses PCIe 6.0 x16. The suggested PSU for the B300 is 1,500 W. Display outputs are motherboard dependent for the Radeon, while the B300 has no outputs. API support also differs: the Radeon supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the B300 lists N/A for DirectX, OpenGL, and Vulkan, reflecting its compute-focused server role.

Release timing is also distinct. The Radeon 760M was released on 2024-01-30, with the predecessor listed as Navi II IGP. The B300 SXM6 AC was released on 2025-09-10, with the predecessor listed as Server Hopper and the successor as Server Rubin. Both are marked as active production parts.

The Verdict

The data supports a clear separation of roles. The AMD Radeon 760M is an integrated graphics solution for systems where power draw is minimal, as indicated by its 15 W TDP and system-shared memory. Its benchmark profile, with an average score of 6,019 and a 35th percentile placement, places it among entry-level GPUs. Its nearest rivals, all within 0.5% of its average score, confirm that it competes with older or lower-tier discrete parts like the RX 6400, GTX 770M, and Quadro P2000. For tasks that fit within its capabilities, such as light graphics or compute workloads, the Radeon 760M delivers a baseline level of performance.

The NVIDIA B300 SXM6 AC is a server accelerator with no display outputs and a 1,100 W TDP. Its single recorded OpenCL score of 369,831 places it at the 100th percentile, and its nearest rivals are all substantial data center products. The 7% lead over the B200 and the 10.4% lead over the H200 NVL indicate that the B300 sits at the top of the current hierarchy. The 288 GB of HBM3e memory and 8.19 TB/s bandwidth are consistent with large-scale compute workloads, and the 592 tensor cores align with AI inference and training tasks.

Choosing between these two products is not a matter of preference but of use case. The Radeon 760M is appropriate for a system that needs integrated graphics with low power consumption. The B300 SXM6 AC is appropriate for a server environment that requires maximum compute throughput and has the power delivery and cooling infrastructure to support it. The benchmark data does not suggest any overlap in their intended applications. The Radeon’s highest recorded score, 30,336 in Geekbench Vulkan, is still lower than the B300’s OpenCL score by more than an order of magnitude. The B300’s performance advantage is consistent across every metric that can be compared.
