Head-to-Head Benchmarks

The database includes two direct head-to-head benchmarks between these cards, both in Geekbench. The first is Geekbench OpenCL. The RTX 4000 Ada scores 146593, while the RTX 5090 D scores 310674. The winner is the RTX 5090 D, with a delta of 52.8 percent in its favor. This is a massive margin, more than doubling the workstation card's output. The second is Geekbench Vulkan. The RTX 4000 Ada scores 123842, while the RTX 5090 D scores 376915. The winner is again the RTX 5090 D, with a delta of 67.1 percent. The margin is even larger in Vulkan than in OpenCL, suggesting the newer architecture has a particular strength in that API.

The RTX 4000 Ada has zero wins in the head-to-head comparison, while the RTX 5090 D has two wins. The average benchmark score for the 4000 Ada is 135218, which is higher than the 77712 average for the 5090 D. However, the 5090 D's average is dragged down by its inclusion of several Passmark tests with low scores, such as Passmark DirectX 10 at 231, DirectX 11 at 371, DirectX 12 at 219, and DirectX 9 at 434. These tests are not representative of the 5090 D's compute capability, as its Geekbench scores show. The 4000 Ada's nearest rivals are the NVIDIA A10M with an average score of 135230, the AMD Radeon PRO W6800 at 135396, the AMD Radeon Pro W6800X Duo at 135774, and the AMD Radeon PRO V620 at 136472. The 4000 Ada sits within 0.9 percent of these cards, showing it is competitive in its workstation class. The 5090 D's nearest rivals are the AMD Radeon RX 6650M XT at 76904, the AMD Radeon RX 6850M XT at 78940, the NVIDIA Tesla P100 PCIe 12 GB at 79396, and the NVIDIA Tesla P100 PCIe 16 GB at 79605. The 5090 D is 1.1 percent ahead of the RX 6650M XT and 2.4 percent behind the Tesla P100 PCIe 16 GB, which places it in a different performance tier entirely.

Where Each One Wins

The RTX 5090 D wins in every head-to-head benchmark recorded. In OpenCL, it is 52.8 percent ahead of the RTX 4000 Ada. In Vulkan, it is 67.1 percent ahead. These are not marginal gains; they are generational leaps. The 5090 D also wins on memory bandwidth, with 1.79 TB/s versus 360.0 GB/s, and on capacity, with 32 GB versus 20 GB. Its FP32 throughput of 104.8 TFLOPS is nearly four times the 26.73 TFLOPS of the 4000 Ada. The 5090 D is the choice for anyone running large compute workloads, high-resolution texture sets, or any application that scales with memory bandwidth and shading units. Its 170 RT cores and 680 tensor cores provide substantial headroom for ray tracing and AI workloads.

The RTX 4000 Ada wins on efficiency and form factor. Its 130 W TDP is less than a quarter of the 575 W TDP of the 5090 D. Its suggested PSU of 300 W is far below the 950 W required for the 5090 D. The 4000 Ada is single-slot and shorter, at 245 mm versus 304 mm, making it suitable for chassis with limited space. It also has a higher percentile ranking among all GPUs at 95, versus 92 for the 5090 D, which indicates that in the broader database context, the 4000 Ada is a more balanced performer relative to its peers. The 4000 Ada's nearest rivals are all workstation cards within 0.9 percent of its average score, meaning it fits into an established ecosystem of professional GPUs. The 5090 D's nearest rivals are a mix of mobile and data center parts, reflecting its unusual position as a consumer card with extreme compute power.

For practical use, the split is clear. The RTX 4000 Ada is for quiet, low-power workstation builds where a single-slot card is required and where the workload does not need more than 20 GB of memory. The RTX 5090 D is for high-end desktop systems where power and space are not constraints and where the priority is maximum compute throughput. The data shows that the 5090 D is the faster card by every measured metric, but the 4000 Ada remains a viable option for its efficiency and compact design. The choice depends on whether the priority is raw performance or physical and electrical footprint.
