NVIDIA RTX PRO 4000 Blackwell

The NVIDIA RTX PRO 4000 Blackwell is an active professional workstation GPU built on the GB203 chip using the Blackwell 2.0 architecture, fabricated on TSMC's 5 nm process. It packs 45,600 million transistors onto a 378 mm² die, achieving a transistor density of 120.6 million per square millimeter. The card sits at the 50th percentile among all GPUs in the database, though its average benchmark score is recorded as 0, meaning the dataset currently lacks direct performance measurements. This analysis relies on the provided theoretical specifications to interpret its position in the professional graphics landscape.

Benchmark Performance

Without aggregated benchmark scores or nearest-rival data in the dataset, performance must be inferred from the card's raw compute and throughput figures. The FP32 compute rate is listed at 36.83 TFLOPS, with FP16 performance matching at a 1:1 ratio of 36.83 TFLOPS. This symmetric FP16/FP32 capability suggests balanced throughput for mixed-precision workloads, common in scientific visualization and AI-assisted rendering. The texture rate reaches 575.4 GTexel/s, driven by 280 texture mapping units, while the pixel rate is 197.3 GPixel/s from 96 ROPs. These figures, combined with a base clock of 1230 MHz and a boost clock of 2055 MHz, indicate a card designed for sustained professional workloads rather than bursty gaming performance.

The 50th percentile ranking places it exactly in the middle of the database's GPU population, but the absence of nearestRivals entries means no percentage deltas can be calculated against specific competitors. The FP32 throughput of 36.83 TFLOPS is the headline number here; when divided by the 140 W TDP, it yields an efficiency figure that stands out for a single-slot professional card. The pixel rate of 197.3 GPixel/s and texture rate of 575.4 GTexel/s suggest that geometry and fill-rate bound tasks, such as high-polygon scenes or large texture streaming, will be handled without immediate bottlenecking. The 1:1 FP16 ratio is particularly notable, as it avoids the common halving of throughput for half-precision operations, allowing neural network inference and denoising passes to run at full speed.

Power and Cooling

The RTX PRO 4000 Blackwell carries a TDP of 140 W, a modest figure for a card with 8,960 shading units. The recommended power supply is 300 W, which leaves a comfortable margin for the rest of a workstation system. Power delivery uses a single 16-pin connector, simplifying cable management in dense chassis. The physical design is single-slot, measuring 241 mm in length, 111 mm in height, and 20 mm in width. This slim profile is a key advantage for multi-GPU configurations or compact workstations, as it allows multiple cards to be stacked without requiring additional slot spacing. The 140 W TDP also implies that a capable air cooler is sufficient, as the thermal load is well within the range of passive or low-profile cooling solutions typically found in professional environments. The 300 W PSU recommendation is conservative, ensuring stability even under transient loads, but the card's own power draw is low enough to fit into existing workstation power budgets without upgrades.

Who Should Consider It

This card targets users who need substantial memory capacity and bandwidth in a single-slot form factor. With 24 GB of GDDR7 memory and 672.0 GB/s of bandwidth, it is well-suited for high-resolution rendering, large simulation datasets, and machine learning inference tasks that require large model weights to reside in VRAM. The 4x DisplayPort 2.1b outputs allow for multi-monitor setups at high refresh rates, which is beneficial for digital content creation and financial data visualization. The 50th percentile performance ranking means it is not a top-tier compute monster, but it is not entry-level either. For 4K and 8K content creation, the 24 GB capacity prevents out-of-memory errors when working with large textures or complex scenes, while the 672.0 GB/s bandwidth ensures that data transfers between VRAM and the GPU cores do not become a bottleneck. The FP32 throughput of 36.83 TFLOPS is adequate for real-time previews and moderate simulation runs, though users requiring extreme compute for heavy offline rendering might look at higher-tier cards. The single-slot design is a critical factor for those building dense workstations with multiple GPUs, as it enables higher compute density per chassis without sacrificing cooling.

How It Compares

The dataset provides no nearestRivals entries for this card, meaning direct percentage comparisons against specific competitor models are impossible. The only positional reference is the 50th percentile ranking among all GPUs in the database. This indicates that half of the tracked GPUs are faster and half are slower, placing the RTX PRO 4000 Blackwell in the median performance tier. Its predecessor is listed as Workstation Ada, but no scores or specifications for that generation are included in the pack, so a generational delta cannot be quantified. The absence of rival data means that conclusions must be drawn from absolute metrics: the 36.83 TFLOPS FP32 rate, the 672.0 GB/s memory bandwidth, and the 140 W power envelope. Compared to a hypothetical card with lower bandwidth, the 672.0 GB/s figure would provide a significant advantage in memory-bound workloads. However, without a specific rival's numbers, any such comparison would be speculative and is therefore omitted. The card's 50th percentile position suggests it competes in the mid-range professional segment, where a balance of compute, memory, and power efficiency is valued over raw peak performance.

Ray Tracing and Feature Set

The RTX PRO 4000 Blackwell includes 70 ray tracing cores and 280 tensor cores, indicating robust support for hardware-accelerated ray tracing and AI-based features. The API support is comprehensive: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 are all listed. DirectX 12 Ultimate ensures compatibility with the latest ray tracing and mesh shading features in Windows applications, while Vulkan 1.4 provides cross-platform access to similar capabilities. The 280 tensor cores are designed for matrix operations, which accelerate denoising, super-resolution, and other neural network workloads that are increasingly common in professional rendering pipelines. The 70 RT cores handle BVH traversal and ray intersection calculations, offloading these tasks from the shading units. The Blackwell 2.0 architecture underpins these features, though the pack does not specify architectural enhancements beyond the core counts. The combination of 70 RT cores and 280 tensor cores suggests that the card is not merely a rasterization workhorse but is equipped for hybrid rendering workflows that blend traditional rasterization with ray-traced effects and AI-assisted post-processing. The 1:1 FP16/FP32 ratio further supports tensor-heavy tasks, as half-precision operations can run at the same throughput as full-precision, which is beneficial for training or inference of smaller models.

Memory Subsystem

The memory subsystem is a defining feature of this card. It uses 24 GB of GDDR7 memory, which is a relatively new memory type that offers high data rates. The bus width is 192 bits, and the effective memory clock is 1750 MHz (28 Gbps effective), resulting in a total bandwidth of 672.0 GB/s. This bandwidth figure is critical for high-resolution workloads because the GPU cores need a steady stream of texture data, geometry, and frame buffers to remain occupied. For 4K rendering, a single frame can require several gigabytes of texture data, and the 24 GB capacity ensures that multiple large textures can reside in VRAM simultaneously, reducing the need to stream from system memory. The 672.0 GB/s bandwidth also facilitates fast read/write operations for compute workloads, such as scientific simulations that repeatedly access large arrays. The 192-bit bus width, while narrower than some higher-tier cards, is compensated by the high effective clock of 28 Gbps, allowing the bandwidth to remain competitive. For 8K content creation, the 24 GB capacity is adequate for most scenes, though extremely large scenes may still exceed this limit. The memory subsystem's efficiency is further enhanced by the 1:1 FP16 ratio, which allows tensor operations to fully utilize the available bandwidth without halving throughput. Overall, the memory configuration is balanced for the card's compute capabilities, ensuring that the 36.83 TFLOPS of FP32 performance is not starved for data.
