NVIDIA B300 SXM6 AC vs NVIDIA GeForce RTX 5060 Comparison

FAQ

Q: What is the primary performance gap between the NVIDIA B300 SXM6 AC and the GeForce RTX 5060 in compute workloads?

A: In the Geekbench OpenCL test, the B300 SXM6 AC scores 369,831, which is 227.9% higher than the RTX 5060’s 112,787. That represents a more than threefold advantage in raw compute throughput.

Q: Which GPU has the higher transistor count and how does that affect density?

A: The B300 SXM6 AC uses 208,000 million transistors on a 1628 mm² die, yielding a density of 127.8M per mm². The RTX 5060 uses 21,900 million transistors on a 181 mm² die, yielding 121.0M per mm². The B300’s larger die allows for far more compute resources.

Q: How do the memory subsystems differ between these two cards?

A: The B300 SXM6 AC features 288 GB of HBM3e memory on a 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RTX 5060 has 8 GB of GDDR7 on a 128-bit bus, providing 448.0 GB/s. The B300 offers nearly 18 times the bandwidth.

Q: What is the form factor difference and what does it imply for system integration?

A: The B300 SXM6 AC is an SXM Module with no display outputs and no power connector listed, designed for server chassis with a 1500 W suggested PSU. The RTX 5060 is a Dual-slot card with a 1x 8-pin connector, a 300 W suggested PSU, and includes 1x HDMI 2.1b plus 3x DisplayPort 2.1b outputs.

Q: Which GPU has the higher percentile ranking among all GPUs in the database?

A: The B300 SXM6 AC is at the 100th percentile, meaning it outperforms every other recorded GPU. The RTX 5060 sits at the 72nd percentile, which places it above the majority but well below the top-tier accelerators.

Q: What is the difference in boost clock speeds?

A: The RTX 5060 has a boost clock of 2497 MHz, while the B300 SXM6 AC boosts to 2032 MHz. Despite the lower clock, the B300’s massive parallel core count gives it a decisive performance lead.

Where Each One Wins

The B300 SXM6 AC wins in every head-to-head benchmark recorded in the database. Its single OpenCL score of 369,831 dwarfs the RTX 5060’s 112,787 in the same test, a 227.9% margin. The B300 also holds the 100th percentile ranking, while the RTX 5060 only reaches the 72nd percentile. This is not a contest of architectural parity; it is a server accelerator versus a consumer graphics card.

The RTX 5060 does have niches where its design is more appropriate, though not where it wins on raw performance. Its 145 W TDP and 300 W suggested PSU make it suitable for standard desktop builds, whereas the B300’s 1100 W TDP and 1500 W suggested PSU require enterprise power delivery. The RTX 5060 also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it fully compatible with consumer gaming and workstation APIs. The B300 lists no API support in the database, which means it lacks those graphics interfaces entirely.

For rasterization-specific work, the RTX 5060’s 119.9 GPixel/s pixel rate exceeds the B300’s 48.77 GPixel/s, and its 299.6 GTexel/s texture rate is lower than the B300’s 1,202.9 GTexel/s. That pixel-rate advantage, combined with 48 ROPs versus the B300’s 24 ROPs, means the RTX 5060 handles traditional display output tasks more efficiently. The B300’s 592 tensor cores and 18,944 shading units are oriented toward AI and compute, not frame rendering.

Architecture Differences

The B300 SXM6 AC uses the GB110 chip with Blackwell Ultra architecture, belonging to the Server Blackwell (Bxx) generation. The RTX 5060 uses the GB206 chip with Blackwell 2.0 architecture, part of the GeForce 50 series. Both are fabricated on TSMC’s 5 nm process, but the similarity ends there.

The B300 packs 208,000 million transistors, which is roughly 9.5 times the RTX 5060’s 21,900 million. Its die size is 1628 mm² versus 181 mm², a difference of nearly ninefold. Transistor density is slightly higher on the B300 at 127.8M per mm² versus 121.0M per mm², meaning the B300 uses its larger area more efficiently.

The B300 has 18,944 shading units, 592 TMUs, and 24 ROPs. The RTX 5060 has 3,840 shading units, 120 TMUs, and 48 ROPs. The B300’s shading unit count is nearly five times higher, and its TMU count is roughly five times higher. The RTX 5060 has double the ROP count, which explains its higher pixel rate.

The B300’s tensor core count is 592, while the RTX 5060 has 120 tensor cores. The B300 also has no listed RT cores, while the RTX 5060 includes 30 RT cores. This reflects their design goals: the B300 is a compute and AI accelerator, the RTX 5060 is a consumer GPU with ray tracing support.

Memory architecture diverges sharply. The B300 uses HBM3e with 288 GB capacity and an 8192-bit bus. The RTX 5060 uses GDDR7 with 8 GB capacity and a 128-bit bus. The B300’s 8.19 TB/s bandwidth is nearly 18 times the RTX 5060’s 448.0 GB/s. The B300’s memory clock is 2000 MHz (8 Gbps effective), while the RTX 5060’s is 1750 MHz (28 Gbps effective).

The bus interface also differs: the B300 uses PCIe 6.0 x16, while the RTX 5060 uses PCIe 5.0 x8. The B300 is an SXM Module with no display outputs, while the RTX 5060 is a Dual-slot card with HDMI 2.1b and DisplayPort 2.1b outputs.

The B300 has a higher base clock in the RTX 5060’s favor, but the B300’s boost clock is lower. The RTX 5060 has a higher pixel rate and more ROPs, while the B300 leads in texture rate, FP32, FP16, and tensor core count. The B300’s release date is later than the RTX 5060’s, and its predecessor and successor are server-class parts.

Head-to-Head Benchmarks

The only shared benchmark in the database is Geekbench OpenCL. The B300 SXM6 AC scores 369,831, while the RTX 5060 scores 112,787. That is a 227.9% lead for the B300, which translates to the B300 delivering more than three times the compute performance in this workload.

Comparing each card to its nearest rivals provides more context. The B300’s closest competitor is the NVIDIA B200, which averages 345,482, putting the B300 7% ahead. The NVIDIA H200 NVL scores 334,891, meaning the B300 is 10.4% faster. The AMD Instinct MI300X scores 317,994, a 16.3% gap. The NVIDIA L40S scores 295,763, which is 25% behind the B300. These deltas show that the B300 does not merely edge out its peers; it leads them by substantial margins.

The RTX 5060’s nearest rivals are much closer. The AMD Radeon 860M averages 26,401, which is 0.3% above the RTX 5060’s 26,331 average. The NVIDIA GeForce MX550 scores 26,421, also 0.3% higher. The AMD Radeon RX 5700 XT 50th Anniversary averages 26,553, a 0.8% lead. The AMD Radeon RX 6750 XT scores 26,011, which is 1.2% below the RTX 5060. These small deltas indicate the RTX 5060 sits in a tightly contested mid-range segment, while the B300 occupies a performance tier where no rival comes within single-digit percentage points.

The B300’s 100th percentile ranking confirms it is the fastest GPU in the entire database. The RTX 5060’s 72nd percentile places it in the upper-middle range but far from the top. The B300’s average benchmark score of 369,831 equals its single OpenCL result, as that is the only test recorded for it. The RTX 5060 averages 26,331 across ten tests, which includes 3DMark Steel Nomad DX12 at 3,628, Geekbench Vulkan at 113,321, and Passmark G3D at 20,891.

The B300’s FP32 throughput of 76.99 TFLOPS is exactly four times the RTX 5060’s 19.18 TFLOPS. Its FP16 performance is also 76.99 TFLOPS with a 1:1 ratio, while the RTX 5060 delivers 19.18 TFLOPS FP16, also 1:1. The B300’s texture rate of 1,202.9 GTexel/s is roughly four times the RTX 5060’s 299.6 GTexel/s. These compute metrics align with the OpenCL result: the B300 is designed for massive parallel workloads, and the data consistently shows a fourfold or greater advantage in raw throughput.

The RTX 5060 does win on pixel rate at 119.9 GPixel/s versus 48.77 GPixel/s, which is a 2.5x advantage in favor of the consumer card. That is a direct consequence of the RTX 5060’s higher ROP count and boost clock. However, pixel rate is not a compute benchmark; it measures rasterization output, which is not relevant to the B300’s server role. In every compute-oriented metric, the B300 maintains a decisive lead.
