NVIDIA B300 vs NVIDIA GeForce RTX 5070 SUPER Comparison

Where Each One Wins

The recorded database contains a single benchmark entry for the NVIDIA GeForce RTX 5070 SUPER, while the NVIDIA B300 has no benchmark scores in the database. The RTX 5070 SUPER scores 2690 points in 3DMark Steel Nomad (DX12), placing it at the 18th percentile among all GPUs in the database. The B300, by contrast, holds a 50th percentile position with an average benchmark score of zero, indicating no measured performance data exists for it. The head-to-head benchmark comparison between the two parts shows zero wins for either side, as no direct comparative tests are recorded.

The RTX 5070 SUPER's percentile ranking at 18 places it below the median of all database GPUs, though its nearest rivals in the database are notably older or lower-tier parts. The NVIDIA Quadro K1100M scores 2664, which is 1 percent lower, the GeForce GT 1030 scores 2662 at 1.1 percent lower, the Intel Arc Pro B50 scores 2660 at 1.1 percent lower, and the GeForce GT 440 scores 2645 at 1.7 percent lower. This clustering suggests the RTX 5070 SUPER's single recorded benchmark places it in close company with legacy or entry-level parts, despite its modern architecture and specifications. The B300, lacking any benchmark scores, cannot be positioned in this manner; its 50th percentile is a default or median assignment rather than a measured outcome.

For use-case separation, the data indicates the RTX 5070 SUPER is the only one of the two with verifiable graphics performance, making it the candidate for client-side rendering workloads where benchmark scores matter. The B300, with no display outputs and no benchmark results, is positioned purely by its server-class feature set rather than any measured graphics capability. The wins distribution of zero and zero reflects that no direct comparison exists, so no performance advantage can be assigned to either part based on recorded tests.

Architecture Differences

The two GPUs share the same 5 nm TSMC process node and both belong to NVIDIA's Blackwell architecture family, but they diverge significantly in implementation. The B300 uses the GB110 chip under the Blackwell Ultra architecture, while the RTX 5070 SUPER uses the GB205 chip under Blackwell 2.0. The B300 is classified under the Server Blackwell (Bxx) generation, whereas the RTX 5070 SUPER belongs to the GeForce 50 generation. This split indicates different design goals: the B300 targets server compute with massive memory and throughput, while the RTX 5070 SUPER targets client graphics with display outputs and standard API support.

Transistor counts differ by a factor of more than three. The B300 packs 104,000 million transistors on its die, while the RTX 5070 SUPER contains 31,100 million. The RTX 5070 SUPER has a recorded die size of 263 mm² and a transistor density of 118.3 million per mm², while the B300's die size is not listed in the database. Shading units, texture mapping units, and tensor cores all follow this scaling pattern: the B300 has 18,944 shading units, 592 TMUs, and 592 tensor cores, while the RTX 5070 SUPER has 6,400 shading units, 200 TMUs, and 200 tensor cores. The B300 has no recorded RT core count, while the RTX 5070 SUPER has 50 RT cores. Raster output units differ inversely: the B300 has only 24 ROPs, while the RTX 5070 SUPER has 80 ROPs.

Memory architecture is a major differentiator. The B300 uses 144 GB of HBM3e on a 4096-bit bus, delivering 4.10 TB/s of bandwidth. The RTX 5070 SUPER uses 18 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s. The B300's memory clock is listed at 2000 MHz with 8 Gbps effective rate, while the RTX 5070 SUPER's memory runs at 1750 MHz with 28 Gbps effective rate. The B300's clock speeds are lower overall: base 1665 MHz and boost 2032 MHz, compared to the RTX 5070 SUPER's base 2325 MHz and boost 2512 MHz. The B300's FP32 throughput is 76.99 TFLOPS versus 32.15 TFLOPS for the RTX 5070 SUPER. FP16 performance shows the largest gap: the B300 delivers 1,231.8 TFLOPS at a 16:1 ratio, while the RTX 5070 SUPER delivers 32.15 TFLOPS at a 1:1 ratio. Pixel rates favor the RTX 5070 SUPER at 201.0 GPixel/s versus 48.77 GPixel/s for the B300, while texture rates favor the B300 at 1,202.9 GTexel/s versus 502.4 GTexel/s.

Power and physical characteristics differ substantially. The B300 has a TDP of 1400 W with a suggested PSU of 1800 W, while the RTX 5070 SUPER has a TDP of 275 W and no suggested PSU listed. The B300 is an SXM module with no display outputs, while the RTX 5070 SUPER is a dual-slot card with a single 16-pin power connector and dimensions of 245 mm length, 115 mm height, and 40 mm width. Both use PCIe 5.0 x16 interfaces. The RTX 5070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the B300 has no recorded API support levels.

FAQ

A: The B300 uses 144 GB of HBM3e on a 4096-bit bus with 4.10 TB/s bandwidth. The RTX 5070 SUPER uses 18 GB of GDDR7 on a 192-bit bus with 672.0 GB/s bandwidth. The B300's memory bandwidth is approximately six times higher.

Q: What is the ROP difference between the two cards?

A: The RTX 5070 SUPER has 80 ROPs, while the B300 has only 24 ROPs. This contributes to the RTX 5070 SUPER's higher pixel rate of 201.0 GPixel/s compared to 48.77 GPixel/s for the B300, indicating the RTX 5070 SUPER is better suited for rasterization-heavy workloads.

Q: Do both cards support the same APIs?

A: No. The RTX 5070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B300 has no recorded API support levels in the database, consistent with its server positioning and lack of display outputs.

Q: What are the power requirements for each?

A: The B300 has a TDP of 1400 W and requires a suggested PSU of 1800 W. The RTX 5070 SUPER has a TDP of 275 W with no suggested PSU listed. The B300's power draw is roughly five times that of the RTX 5070 SUPER.

Q: Which GPU has a higher clock speed?

A: The RTX 5070 SUPER runs at a base clock of 2325 MHz and a boost clock of 2512 MHz. The B300 runs at a base clock of 1665 MHz and a boost clock of 2032 MHz. The RTX 5070 SUPER's clocks are considerably higher despite the B300's larger compute resources.

Head-to-Head Benchmarks

The database records no head-to-head benchmark comparisons between the NVIDIA B300 and the NVIDIA GeForce RTX 5070 SUPER. The head-to-head benchmark array is empty, and the wins tally shows zero for both parts. As a result, no direct performance deltas can be computed between these two GPUs from recorded data. The only benchmark score available belongs to the RTX 5070 SUPER: 2690 points in 3DMark Steel Nomad (DX12). This single measurement places it at the 18th percentile among all GPUs, with its nearest rivals being the NVIDIA Quadro K1100M at 2664 (1 percent lower), the NVIDIA GeForce GT 1030 at 2662 (1.1 percent lower), the Intel Arc Pro B50 at 2660 (1.1 percent lower), and the NVIDIA GeForce GT 440 at 2645 (1.7 percent lower). These deltas are small, all under 2 percent, indicating that the RTX 5070 SUPER's recorded performance is only marginally ahead of these legacy parts in this specific test.

The B300 has no benchmark scores in the database, meaning its performance cannot be compared numerically to the RTX 5070 SUPER or any other GPU. Its 50th percentile ranking is a default assignment rather than a measured result. The specification data, however, allows for an indirect comparison. The B300's FP32 throughput of 76.99 TFLOPS is more than double the RTX 5070 SUPER's 32.15 TFLOPS, and its texture rate of 1,202.9 GTexel/s is roughly 2.4 times higher. The B300's memory bandwidth of 4.10 TB/s is approximately six times the RTX 5070 SUPER's 672.0 GB/s. Conversely, the RTX 5070 SUPER has a pixel rate of 201.0 GPixel/s, which is more than four times the B300's 48.77 GPixel/s, and it has 80 ROPs versus 24, indicating rasterization-oriented design. The RTX 5070 SUPER also has higher clocks, with a boost of 2512 MHz versus 2032 MHz, and it is the only one of the two with any recorded benchmark result. Without head-to-head data, the performance relationship between these two parts rests entirely on their divergent specifications and the single RTX 5070 SUPER score.
