NVIDIA B300 vs NVIDIA GeForce RTX 5060 GB205 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark comparisons for the NVIDIA B300 and the NVIDIA GeForce RTX 5060 GB205. The winsA and winsB fields are both zero, indicating that neither product has a measured victory over the other in any shared test. This absence of data is consistent with the fundamental positioning of the two devices: the B300 is a server-grade accelerator with a 1400 W TDP, while the RTX 5060 is a consumer graphics card with a 145 W TDP. The benchmark suite has not produced a single comparable score, so any quantitative ranking between them must rely on the specification-level differences recorded in the database.

The available data does show a large gap in raw compute metrics. The B300 delivers 76.99 TFLOPS of FP32 throughput, while the RTX 5060 delivers 19.18 TFLOPS. That places the B300 at roughly four times the FP32 rate of the RTX 5060, a direct comparison of recorded numbers. In FP16, the divergence becomes extreme: the B300 reaches 1,231.8 TFLOPS using a 16:1 ratio, whereas the RTX 5060 manages 19.18 TFLOPS at a 1:1 ratio. The B300's FP16 figure is over 64 times higher, reflecting its tensor-heavy design for server workloads, not a like-for-like gaming metric.

Pixel and texture rates also separate the two clearly. The RTX 5060 has a pixel rate of 119.9 GPixel/s, which is higher than the B300's 48.77 GPixel/s. The RTX 5060 also has 48 ROPs compared to 24 ROPs on the B300. In texture throughput, the B300 counters with 1,202.9 GTexel/s versus 299.6 GTexel/s for the RTX 5060, a fourfold advantage. These numbers illustrate that the B300 is not optimized for rasterization output, despite its enormous shading and tensor resources.

Where Each One Wins

Based on the recorded data, the B300 wins outright in compute-heavy categories: FP32 performance, FP16 performance, texture rate, and memory bandwidth. Its 4.10 TB/s of memory bandwidth dwarfs the RTX 5060's 448.0 GB/s, a difference of nearly an order of magnitude. The B300 also carries 144 GB of HBM3e memory, while the RTX 5060 has 8 GB of GDDR7. For server-side training, inference, or large-scale data processing, the B300's recorded specifications put it in a different class entirely.

The RTX 5060 wins in pixel throughput and ROP count, as noted above. Its 119.9 GPixel/s is more than double the B300's 48.77 GPixel/s, and its 48 ROPs are exactly double the B300's 24. The RTX 5060 also has a higher base clock of 2280 MHz and boost clock of 2497 MHz, compared to 1665 MHz and 2032 MHz for the B300. For traditional graphics rendering, where pixel fill and clock speed matter more than raw FP16 tensor throughput, the RTX 5060 has the edge in the recorded metrics.

The RTX 5060 has a lower TDP at 145 W compared to 1400 W for the B300, and its suggested PSU is 300 W versus 1800 W. The database also records display outputs for the RTX 5060 (1x HDMI 2.1b, 3x DisplayPort 2.1b), while the B300 has no outputs, making it unsuitable for direct display tasks. The RTX 5060's dual-slot form factor and 241 mm length stand against the B300's SXM Module, which is a server board form factor.

Architecture Differences

The two GPUs share the same 5 nm process node and TSMC as the foundry, but the designs diverge sharply. The B300 uses the GB110 chip and Blackwell Ultra architecture, belonging to the Server Blackwell (Bxx) generation. The RTX 5060 uses the GB205 chip and Blackwell 2.0 architecture, in the GeForce 50 generation. The B300's transistor count is recorded at 104,000 million, while the RTX 5060 has 31,100 million. The RTX 5060 has a die size of 263 mm² and a transistor density of 118.3M per mm²; the B300's die size and density are not recorded.

Memory architecture is a key differentiator. The B300 uses a 4096-bit bus with HBM3e memory, while the RTX 5060 uses a 128-bit bus with GDDR7. The B300's memory clock is listed as 2000 MHz with 8 Gbps effective, while the RTX 5060 runs at 1750 MHz with 28 Gbps effective. Even though the RTX 5060 has a higher effective memory clock, the B300's much wider bus delivers far more total bandwidth.

Compute resources differ by proportion. The B300 has 18,944 shading units, 592 TMUs, and 592 tensor cores. The RTX 5060 has 3,840 shading units, 120 TMUs, and 120 tensor cores. The B300 has no recorded RT core count, while the RTX 5060 has 30 RT cores. The B300's FP16 performance of 1,231.8 TFLOPS at a 16:1 ratio indicates a design focused on tensor operations, whereas the RTX 5060's FP16 at 1:1 matches its FP32 rate, suggesting a more balanced compute approach for graphics and general workloads.

The API support also separates them. The RTX 5060 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B300 has no recorded API support values, which aligns with its server orientation where graphics APIs are not a priority. The B300 connects via PCIe 5.0 x16, while the RTX 5060 uses PCIe 5.0 x8. The B300 has no power connectors listed and no display outputs, while the RTX 5060 uses a single 8-pin connector and offers standard display outputs.
