NVIDIA Quadro RTX 4000

The NVIDIA Quadro RTX 4000 is a Turing-architecture GPU built around the TU104 chip, fabricated by TSMC on a 12 nm process with 13,600 million transistors on a 545 mm² die. It belongs to the Quadro Turing (Tx000) generation, was released on 2018-11-12, and sits between the Quadro Volta and Workstation Ampere product lines. In the benchmark database it records an average benchmark score of 18852 and a 60th percentile ranking across all GPUs, with a launch MSRP of 899 USD. The card carries a base clock of 1005 MHz, a boost clock of 1545 MHz, and uses a PCIe 3.0 x16 bus interface.

Memory Subsystem

The NVIDIA Quadro RTX 4000 is equipped with 8 GB of GDDR6 memory on a 256-bit bus. The memory clock is 1625 MHz, quoted as 13 Gbps effective, and the resulting memory bandwidth is 416.0 GB/s. This combination defines the card’s ability to feed a large, continuously accessed frame buffer, which is especially relevant for high-resolution rendering where the amount of pixel data being written and read grows quickly.

The memory path serves a GPU with 2304 shading units, 144 texture mapping units, and 64 ROPs. The card also reaches a pixel rate of 98.88 GPixel/s and a texture rate of 222.5 GTexel/s. Those rates are heavily dependent on bandwidth, and the 256-bit bus width is the hardware mechanism that allows the 416.0 GB/s figure to be sustained. In practical terms, the 8 GB VRAM capacity is the ceiling for how much frame data and geometry can be held locally, while the bandwidth determines how quickly the compute and raster units can read from and write to that memory. For high-resolution work, 416.0 GB/s is a meaningful data throughput figure, and the 8 GB frame buffer is the amount of immediate video memory available before data must be swapped.

How It Compares

Against the NVIDIA Tesla K80, the Quadro RTX 4000 is effectively tied. The K80’s average score is 18866, and the Quadro’s average score is 18852, producing a delta of -0.1%. This is the closest rival in the database by a large margin.

Against the NVIDIA Tesla K20m, the Quadro trails by 0.8%. The K20m holds an average score of 19011, so the Quadro’s 18852 aggregate result is slightly lower, but the gap is still under one percent.

Against the NVIDIA GeForce RTX 4050 Mobile, the Quadro sits 1.0% behind. The RTX 4050 Mobile posts an average score of 19049, while the Quadro RTX 4000 posts 18852. The delta of -1.0% shows a consistent, if modest, deficit in the aggregate benchmark index.

Against the AMD Radeon 780M, the Quadro is 1.1% behind. The Radeon 780M has the highest average score among the four nearest rivals at 19057, and the Quadro’s delta of -1.1% is the largest negative gap in this group. Even so, the entire rival cluster is separated by a narrow range of average scores.

Benchmark Performance

The overall benchmark position can be summarized by the average benchmark score of 18852 and the 60th percentile figure. The Quadro RTX 4000 is not a leading GPU in the database; it sits in the middle of the distribution, and all four nearest rival deltas are negative. The deltas run from -0.1% against the Tesla K80 to -1.1% against the Radeon 780M, meaning the aggregate scores of the nearest competitors are tightly grouped.

Individual benchmark results vary more widely than the aggregate score might suggest. In the 3DMark Steel Nomad DX12 test, the Quadro scores 1873. Geekbench OpenCL returns 85166, while Geekbench Vulkan returns 78844, showing substantially higher results in compute-oriented tests than in the DirectX 12 3D test. PassMark results are split by API: DirectX 9 scores 205, DirectX 10 scores 108, DirectX 11 scores 128, and DirectX 12 scores 52. The general-purpose PassMark G2D score is 846, the G3D score is 15117, and the GPU compute score is 6176.

Raw compute figures from the fact pack align with that mixed profile. FP32 performance is 7.119 TFLOPS, while FP16 performance is 14.24 TFLOPS with a 2:1 ratio. These are the theoretical compute ceilings, while the PassMark GPU compute result of 6176 is a measured workload data point. The 3DMark Steel Nomad DX12 score of 1873 and PassMark DirectX 12 score of 52 are the least remarkable results in the suite, which suggests modern DirectX 12 rendering is not the primary strength of this configuration.

Ray Tracing and Feature Set

The Quadro RTX 4000 is built on the Turing architecture with the TU104 chip. It includes 36 RT cores for ray tracing work and 288 tensor cores for tensor-accelerated operations. The underlying chip is fabricated on TSMC’s 12 nm process with 13,600 million transistors, a die size of 545 mm², and a transistor density of 25.0M per mm².

The API feature set includes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This gives the card support for modern graphics APIs at the levels listed in the data. The display outputs are 3x DisplayPort 1.4a and 1x USB Type-C, providing the physical output options for multi-display workstation setups. The ray tracing and tensor core counts are the specific hardware facts relevant to workloads that use those paths; the 36 RT cores are the ray tracing block, and the 288 tensor cores are the compute-oriented block for tensor operations.

Power and Cooling

The Quadro RTX 4000 is a single-slot design. Its physical dimensions are 241 mm in length, which is 9.5 inches, and 111 mm in height, which is 4.4 inches. The TDP is 160 W, and power is supplied through a single 1x 8-pin power connector. The suggested PSU rating is 450 W, which gives a defined power-supply target for system builders. The base clock is 1005 MHz and the boost clock is 1545 MHz, both running within that 160 W power envelope. The production status is end-of-life, so this is a card that has already completed its production cycle rather than a newly available product.

Who Should Consider It

The Quadro RTX 4000 fits a middle-of-the-database GPU profile, with a 60th percentile ranking and an average score of 18852. Its nearest rivals are all within a narrow range: the Tesla K80 is 0.1% ahead, the Tesla K20m is 0.8% ahead, the GeForce RTX 4050 Mobile is 1.0% ahead, and the Radeon 780M is 1.1% ahead. Users comparing these cards on the aggregate benchmark index should expect performance parity rather than a decisive winner.

The strongest data points are compute-oriented: Geekbench OpenCL scores 85166, Geekbench Vulkan scores 78844, and PassMark GPU compute scores 6176. Those numbers make the card more compelling for workloads that exercise compute throughput. The 8 GB GDDR6 frame buffer and 416.0 GB/s memory bandwidth are the relevant hardware facts for high-resolution frame buffering, and the single-slot width plus 160 W TDP define the physical and power requirements. Modern DirectX 12 3D workloads are not the strongest area, as the 3DMark Steel Nomad DX12 score of 1873 and PassMark DirectX 12 score of 52 show. Users who prioritize compute results, need a single-slot card, and can work with the 8-pin power connector and 450 W suggested PSU have a clearly documented hardware profile to evaluate.
