NVIDIA RTX 5880 Ada Generation vs NVIDIA Rubin GPU Comparison

Head-to-Head Benchmarks

The database contains benchmark results for the NVIDIA RTX 5880 Ada Generation, but the NVIDIA Rubin GPU has no recorded benchmark scores. The Rubin GPU's average benchmark score is listed as 0, and its percentile ranking sits at 50, which reflects the absence of tested performance data rather than actual measured performance. The RTX 5880 Ada Generation, by contrast, has a recorded average benchmark score of 45,972 and ranks in the 85th percentile among all GPUs in the database.

The RTX 5880 Ada Generation shows concrete results across multiple test suites. In Geekbench OpenCL, it scores 326,898. Its Passmark G3D score is 25,096, while its Passmark GPU Compute score is 14,208. The older DirectX tests show a wide spread: Passmark DirectX 9 delivers a score of 335, DirectX 10 scores 167, DirectX 11 scores 228, and DirectX 12 scores 70. The 2D test result is 777.

Since the Rubin GPU has no benchmark entries, direct head-to-head comparisons cannot be established from measured data. The nearest rivals for the RTX 5880 Ada Generation provide context for its performance tier: the NVIDIA RTX A2000 scores 46,043 on average, which is 0.2% higher; the AMD Radeon RX 5600M scores 46,601, which is 1.4% higher; the Intel Arc A730M scores 45,592, which is 0.8% lower; and the AMD Radeon Pro 5500 XT scores 45,384, which is 1.3% lower. The RTX 5880 Ada Generation sits within 1.4% of these four rivals, clustering tightly around a similar average score band despite its much larger memory capacity and higher shading unit count.

The recorded data shows that the RTX 5880 Ada Generation's average score of 45,972 places it just below the RTX A2000 and RX 5600M, but above the Arc A730M and Radeon Pro 5500 XT. The delta percentages are small, indicating that in aggregate benchmark performance, these five GPUs are closely matched. However, the RTX 5880 Ada Generation's individual test scores, particularly the Geekbench OpenCL result at 326,898, demonstrate strong compute capability that the aggregate average may understate.

Where Each One Wins

The RTX 5880 Ada Generation wins in every measurable benchmark category because the Rubin GPU has no recorded data. The RTX 5880 Ada Generation's Passmark G3D score of 25,096 and Passmark GPU Compute score of 14,208 indicate solid rasterization and compute throughput. Its Geekbench OpenCL score of 326,898 reflects substantial general-purpose GPU compute performance. The DirectX 9 score of 335 and DirectX 11 score of 228 show compatibility with legacy graphics APIs, while the DirectX 12 score of 70 and DirectX 10 score of 167 indicate more limited performance under those specific test conditions.

For the Rubin GPU, the database lists zero benchmark results, so no use-case wins can be attributed to it based on measured performance. Its specifications suggest a server-oriented design, but the absence of test data means any performance claims would be speculative. The RTX 5880 Ada Generation, with its workstation generation label "Workstation Ada (x000A)", targets professional graphics workloads, and its benchmark scores confirm capability in both compute and traditional rendering tasks.

The nearest rival data for the RTX 5880 Ada Generation shows that its average score is nearly identical to the RTX A2000 and RX 5600M, with deltas of -0.2% and -1.4% respectively. This indicates that in aggregate, the RTX 5880 Ada Generation does not dominate its closest competitors despite its larger memory and higher core counts. The small deltas suggest that for typical benchmark workloads, these GPUs perform within a narrow band, and the RTX 5880 Ada Generation's advantages may lie in specific application scenarios not captured by these aggregate scores.

The Verdict

The recorded data shows that the RTX 5880 Ada Generation is a fully benchmarked workstation GPU with a 45,972 average score and an 85th percentile ranking. Its nearest rivals score within 1.4% of its average, indicating competitive parity in aggregate performance. The Rubin GPU has no benchmark scores, so its measured performance is unknown.

For workstation graphics tasks, the RTX 5880 Ada Generation is the only option with verified data. It delivers 69.27 TFLOPS of FP32 compute, 48 GB of GDDR6 memory with 864.0 GB/s bandwidth, and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its 176 ROPs and 433.0 GPixel/s pixel rate suit traditional rendering workloads. Its dual-slot form factor, 285 W TDP, and 600 W suggested PSU make it compatible with standard workstation power configurations. The 4x DisplayPort 1.4a outputs support multi-monitor setups.

The Rubin GPU targets server applications. Its 288 GB HBM4 memory with 22.1 TB/s bandwidth, 130.0 TFLOPS FP32, and 260.0 TFLOPS FP16 (2:1) indicate a design aimed at memory-bandwidth-intensive and FP16-heavy compute workloads. Its 2300 W TDP, SXM Module form factor, and 2700 W suggested PSU require specialized server infrastructure. The absence of display outputs and graphics API support confirms its server-only intent. The Rubin GPU's 24 ROPs and 54.41 GPixel/s pixel rate show that rasterization is not its purpose.

The RTX 5880 Ada Generation has a release date of January 4, 2024, while the Rubin GPU's release date is December 31, 2025. Both are listed as active in production. The RTX 5880 Ada Generation's successor is "Blackwell PRO W", and the Rubin GPU's predecessor is "Server Blackwell".

The data indicates the RTX 5880 Ada Generation is the appropriate choice for professional workstation graphics, where measured benchmark performance and display output support are required. The Rubin GPU is positioned for server deployments where massive memory capacity, high FP16 throughput, and extreme bandwidth take priority over rasterization and graphics compatibility. The 85th percentile ranking of the RTX 5880 Ada Generation versus the 50th percentile (with zero scores) for the Rubin GPU underscores that only one of these GPUs has verified performance data in the database.
