NVIDIANVIDIA B300 Specifications
GPU Core
Shader units and compute resources
The NVIDIA B300 GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.
B300 Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the B300's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The B300 by NVIDIA dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
NVIDIA's B300 Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The B300's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.
B300 by NVIDIA Cache
On-chip cache hierarchy
On-chip cache provides ultra-fast data access for the B300, reducing the need to fetch data from slower VRAM. L1 and L2 caches store frequently accessed data close to the compute units. AMD's Infinity Cache (L3) dramatically increases effective bandwidth, improving GPU benchmark performance without requiring wider memory buses. Larger cache sizes help maintain high frame rates in memory-bound scenarios and reduce power consumption by minimizing VRAM accesses.
B300 Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the NVIDIA B300 against other graphics cards. FP32 (single-precision) performance, measured in TFLOPS, indicates compute capability for gaming and general GPU workloads. FP64 (double-precision) matters for scientific computing. Pixel and texture fill rates determine how quickly the GPU can render complex scenes. While real-world GPU benchmark results depend on many factors, these specifications help predict relative performance levels.
B300 Ray Tracing & AI
Hardware acceleration features
The NVIDIA B300 includes dedicated hardware for ray tracing and AI acceleration. RT cores handle real-time ray tracing calculations for realistic lighting, reflections, and shadows in supported games. Tensor cores (NVIDIA) or XMX cores (Intel) accelerate AI workloads including DLSS, FSR, and XeSS upscaling technologies. These features enable higher visual quality without proportional performance costs, making the B300 capable of delivering both stunning graphics and smooth frame rates in modern titles.
Blackwell Ultra Architecture & Process
Manufacturing and design details
The NVIDIA B300 is built on NVIDIA's Blackwell Ultra architecture, which defines how the GPU processes graphics and compute workloads. The manufacturing process node affects power efficiency, thermal characteristics, and maximum clock speeds. Smaller process nodes pack more transistors into the same die area, enabling higher performance per watt. Understanding the architecture helps predict how the B300 will perform in GPU benchmarks compared to previous generations.
Power & Thermal
TDP and power requirements
Power specifications for the NVIDIA B300 determine PSU requirements and thermal management needs. TDP (Thermal Design Power) indicates the heat output under typical loads, guiding cooler selection. Power connector requirements ensure adequate power delivery for stable operation during demanding GPU benchmarks. The suggested PSU wattage accounts for the entire system, not just the graphics card. Efficient power delivery enables the B300 to maintain boost clocks without throttling.
B300 by NVIDIA Physical & Connectivity
Dimensions and outputs
Physical dimensions of the NVIDIA B300 are critical for case compatibility. Card length, height, and slot width determine whether it fits in your chassis. The PCIe interface version affects bandwidth for communication with the CPU. Display outputs define monitor connectivity options, with modern cards supporting multiple high-resolution displays simultaneously. Verify these specifications against your case and motherboard before purchasing to ensure a proper fit.
NVIDIA API Support
Graphics and compute APIs
API support determines which games and applications can fully utilize the NVIDIA B300. DirectX 12 Ultimate enables advanced features like ray tracing and variable rate shading. Vulkan provides cross-platform graphics capabilities with low-level hardware access. OpenGL remains important for professional applications and older games. CUDA (NVIDIA) and OpenCL enable GPU compute for video editing, 3D rendering, and scientific applications. Higher API versions unlock newer graphical features in GPU benchmarks and games.

About NVIDIA B300
The NVIDIA B300 is a server accelerator built around the GB110 chip and the Blackwell Ultra architecture, listed under the Server Blackwell (Bxx) generation. It uses TSMC's 5 nm process and integrates 104,000 million transistors. Production status is Active, with a release date of 2025-09-10, and it sits between the Server Hopper and Server Rubin generations in the product line. The fact pack identifies the slot width as SXM Module and the display outputs as "No outputs," which immediately positions this part as a compute-focused module rather than a desktop graphics card.
Power and Cooling
The B300's TDP is 1400 W, and the suggested PSU is 1800 W. That is a substantial power envelope, and the data implies the PSU recommendation accounts for the host system around the accelerator, not just the module itself. The slot width is SXM Module, and the fact pack lists no power connector details; this suggests the power delivery path is handled by the server backplane or chassis rather than user-attached cables. Since no dimensions are recorded, the data cannot describe physical clearance or cooler geometry. The 1400 W TDP nonetheless indicates a high-density thermal load, so the cooling solution needs to match a server SXM environment. The fact pack contains no fan, heatsink, or liquid-cooling specification, but the power numbers alone make clear this is not a conventional expansion card.
Memory Subsystem
The B300 carries 144 GB of HBM3e memory on a 4096-bit bus. The memory clock is 2000 MHz, listed as 8 Gbps effective. Total bandwidth is 4.10 TB/s. This is a very wide memory path, and the capacity is large enough for workloads that keep big models or datasets resident on the accelerator. At high resolutions, rendering workloads typically need both large frame buffers and high bandwidth; the B300 has the bandwidth and capacity on paper, but its "No outputs" field means any framebuffer it produces is never sent to a display. The 4.10 TB/s bandwidth is better understood as a pipe for compute data movement feeding the 18,944 shading units. The 4096-bit bus is the physical mechanism behind that bandwidth; the memory type and speed encode how quickly data can be cycled through the module.
Ray Tracing and Feature Set
The fact pack does not list an RT core count, so ray tracing capability cannot be quantified from this data. There are 592 tensor cores, which points toward matrix-heavy compute, though the pack does not explicitly connect these tensor cores to specific APIs or workloads. The API fields for DirectX, OpenGL, and Vulkan are all null, so graphics API compatibility is not specified in the fact pack. The bus interface is PCIe 5.0 x16. The absence of display outputs reinforces that this is a compute accelerator. The feature set, as recorded, combines a large tensor core presence with no raster output path and no graphics API entries; that combination suggests the B300 is aimed at systems where rendering to a screen is irrelevant.
How It Compares
The nearestRivals list for the B300 is empty. Therefore, there are no named rival products, no rival scores, and no deltaPct values to analyze. Without that data, a direct position statement against specific competitors is impossible. The only broad reference point is percentileVsAllGpus, which is 50. If taken literally, that would place the B300 at the midpoint of all GPUs in the database, but the average benchmark score is 0, and no benchmark rows are populated, so the percentile is not anchored to measured workloads. The predecessor field names Server Hopper and the successor field names Server Rubin; those names define generation order in the product line, but not competitive performance. In this database state, the B300's relative standing must be treated as undefined rather than inferred.
Who Should Consider It
The B300 is not for anyone needing a display connection, because it has no outputs. The 1400 W TDP and the suggested 1800 W PSU mean it belongs in high-power server infrastructure, not a desktop chassis. The 144 GB HBM3e memory and 4.10 TB/s bandwidth make it suitable for workloads where large datasets must stay close to the compute engine. The FP32 throughput of 76.99 TFLOPS provides general compute headroom, while the FP16 throughput of 1,231.8 TFLOPS is listed with a 16:1 ratio, indicating a design that heavily favors lower-precision compute paths. The average benchmark score of 0 means there is no measured performance data to support resolution or settings-specific recommendations; any guidance would have to come from the hardware facts alone. Those facts point to a server compute module with Blackwell Ultra architecture, PCIe 5.0 x16 connectivity, SXM Module form factor, and no rasterized output capability.
