NVIDIA B300 SXM6 AC vs NVIDIA GeForce RTX 4060 Comparison

The NVIDIA B300 SXM6 AC and the NVIDIA GeForce RTX 4060 occupy opposite ends of the hardware spectrum, and the recorded data confirms this split. The database contains a single shared benchmark between the two, the Geekbench OpenCL test, where the B300 SXM6 AC scored 369,831 points against 95,057 for the RTX 4060. That is a 289.1% advantage for the server module. The B300 SXM6 AC also holds a perfect 100th percentile ranking among all GPUs in the database, while the RTX 4060 sits at the 61st percentile. The RTX 4060 has additional benchmark entries from 3DMark and PassMark suites, but no direct comparison exists for those tests against the B300 SXM6 AC.

Head-to-Head Benchmarks

The only direct head-to-head result is the Geekbench OpenCL test. The B300 SXM6 AC delivers 369,831 points, which places it far above its nearest rivals in the database. The NVIDIA B200 scores 345,482, the NVIDIA H200 NVL scores 334,891, the AMD Instinct MI300X scores 317,994, and the NVIDIA L40S scores 295,763. The delta percentages show the B300 SXM6 AC leading the B200 by 7%, the H200 NVL by 10.4%, the MI300X by 16.3%, and the L40S by 25%. This OpenCL score indicates substantial compute headroom over the closest competing accelerators, not a marginal edge.

The RTX 4060, by contrast, scores 95,057 in the same OpenCL test. Its nearest rivals in the database are all much older or lower-powered parts: the AMD Radeon HD 7790 averages 17,666, the AMD Radeon 780M averages 17,588, the AMD Radeon Pro 560 averages 17,551, and the AMD Radeon Pro 460 averages 17,509. The delta percentages are -0.2%, 0.3%, 0.5%, and 0.7%, respectively. Those deltas are tiny, meaning the RTX 4060's OpenCL score is statistically close to those older products, despite the architectural gap in release dates. The RTX 4060's OpenCL result is roughly 3.9 times higher than its nearest rival's average, but the delta percentages in the database indicate that the rival scores are nearly identical to each other, not to the RTX 4060.

For the RTX 4060, additional benchmarks paint a fuller picture of its performance envelope. The 3DMark Steel Nomad DX12 test yields 2,302 points. PassMark results include a G3D score of 19,545, a GPU compute score of 9,213, a DirectX 9 score of 236, a DirectX 10 score of 103, a DirectX 11 score of 175, a DirectX 12 score of 76, and a G2D score of 1,037. These figures are not comparable to the B300 SXM6 AC because the server module has no entries for those tests. The B300 SXM6 AC only appears once in the database, with the single OpenCL score.

The absence of overlapping tests beyond OpenCL limits the head-to-head analysis to one data point. That data point is unambiguous: the B300 SXM6 AC leads by 289.1%. The scale of that lead matters. A 289.1% delta means the server module delivers roughly 3.89 times the OpenCL compute performance of the RTX 4060. The RTX 4060's nearest rivals in the database are within 0.7% of its average score, so its performance class is well established. The B300 SXM6 AC's nearest rivals are 7% to 25% behind, so its performance class is also clear. These are not competing products in the same tier; they are separated by multiple orders of magnitude in compute capability.

The Verdict

The data indicates that the B300 SXM6 AC is designed for workloads that demand massive parallel compute, while the RTX 4060 targets conventional graphics and lighter compute tasks. The B300 SXM6 AC uses a GB110 chip on the Blackwell Ultra architecture, built on a 5 nm process at TSMC, with 208,000 million transistors on a 1,628 mm² die. It has 18,944 shading units, 592 TMUs, 24 ROPs, 592 tensor cores, and 288 GB of HBM3e memory on an 8,192-bit bus, delivering 8.19 TB/s of bandwidth. Its FP32 performance is 76.99 TFLOPS, and FP16 is also 76.99 TFLOPS with a 1:1 ratio. The module consumes 1,100 W TDP with a suggested PSU of 1,500 W, connects via PCIe 6.0 x16, and has no display outputs. It is marked as active production with a release date of September 10, 2025.

The RTX 4060 uses the AD107 chip on the Ada Lovelace architecture, also on a 5 nm TSMC process, with 18,900 million transistors on a 159 mm² die. It has 3,072 shading units, 96 TMUs, 48 ROPs, 24 RT cores, 96 tensor cores, and 8 GB of GDDR6 memory on a 128-bit bus, delivering 272.0 GB/s of bandwidth. Its FP32 performance is 15.11 TFLOPS, and FP16 is also 15.11 TFLOPS with a 1:1 ratio. The card has a 115 W TDP with a suggested PSU of 300 W, uses PCIe 4.0 x8, and supports 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs. It is end-of-life with a release date of May 17, 2023, and a launch MSRP of 299 USD.

The verdict is straightforward from the recorded data. The B300 SXM6 AC wins the only shared benchmark by a wide margin, holds the top percentile ranking, and its nearest rivals are all large-scale accelerators. The RTX 4060 wins no shared benchmarks, holds a mid-tier percentile, and its nearest rivals are older or integrated parts. For compute density, the B300 SXM6 AC is the clear choice. For any workload requiring display output, the RTX 4060 is the only one of the two with video connectors. The B300 SXM6 AC has no display outputs, so it cannot drive a monitor.

Where Each One Wins

The B300 SXM6 AC wins in raw compute throughput. The OpenCL score of 369,831 versus 95,057, a 289.1% lead, establishes dominance in general-purpose GPU compute. Its memory subsystem also points to specific strengths: 288 GB of HBM3e with 8.19 TB/s bandwidth versus 8 GB of GDDR6 with 272.0 GB/s. That is 36 times the memory capacity and roughly 30 times the bandwidth, based solely on the numbers in the database. The FP32 and FP16 figures are both 76.99 TFLOPS for the B300 SXM6 AC, versus 15.11 TFLOPS for the RTX 4060 in both precisions. The server module has 18,944 shading units and 592 tensor cores, while the RTX 4060 has 3,072 shading units and 96 tensor cores. The B300 SXM6 AC also uses PCIe 6.0 x16, double the bus generation of the RTX 4060's PCIe 4.0 x8.

The RTX 4060 wins in tasks tied to graphics and display. It has 48 ROPs versus 24 on the B300 SXM6 AC, and its pixel rate is 118.1 GPixel/s versus 48.77 GPixel/s. Its texture rate is 236.2 GTexel/s versus 1,202.9 GTexel/s on the B300 SXM6 AC, but the RTX 4060 still outputs to monitors. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the B300 SXM6 AC lists N/A for all three APIs. The RTX 4060 has 24 RT cores, which the B300 SXM6 AC does not list at all. The RTX 4060 also has a much lower TDP of 115 W versus 1,100 W, and its dimensions are 240 mm in length, 111 mm in height, and 40 mm in width, making it a standard dual-slot card. The B300 SXM6 AC is an SXM module, which is a different physical form factor.

The PassMark scores for the RTX 4060 show its graphics-focused design: a G3D score of 19,545 and a G2D score of 1,037. These are not compared to the B300 SXM6 AC, but they indicate the RTX 4060 processes 2D and 3D graphics workloads. The DirectX 9 through 12 scores range from 76 to 236, with the highest in DirectX 9. The B300 SXM6 AC has no equivalent entries, so no direct comparison is possible for those tests.

The B300 SXM6 AC lists no API support, while the RTX 4060 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Production status and release timing also differ. The B300 SXM6 AC is active, released on September 10, 2025, with a predecessor of Server Hopper and a successor of Server Rubin. The RTX 4060 is end-of-life, released on May 17, 2023, with a predecessor of GeForce 30 and a successor of GeForce 50. The RTX 4060 has a launch MSRP of 299 USD. The B300 SXM6 AC has no launch MSRP in the database. The physical dimensions of the RTX 4060 are 240 mm in length, 111 mm in height, and 40 mm in width. The B300 SXM6 AC lists no length, height, or width.
