NVIDIA GeForce RTX 5090 vs NVIDIA RTX 4000 SFF Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data contains two directly comparable benchmark results for these cards, both compute-oriented tests from Geekbench. In the OpenCL test, the NVIDIA GeForce RTX 5090 scores 334,370 points, while the NVIDIA RTX 4000 SFF Ada Generation scores 124,812 points. That puts the RTX 5090 ahead by 62.7 percent, a substantial margin that reflects the raw compute gap between the two. The Vulkan result is even more lopsided: the RTX 5090 reaches 376,728 points against 109,364 points for the RTX 4000 SFF Ada, a 71 percent advantage. In both recorded head-to-head comparisons, the RTX 5090 wins outright, and the RTX 4000 SFF Ada Generation records zero wins across the shared test set.

The broader benchmark averages reinforce this pattern, though with an important caveat. The RTX 4000 SFF Ada Generation posts an average benchmark score of 117,088 across its two Geekbench entries, while the RTX 5090 averages 79,842 across a much wider suite that includes Passmark DirectX tests and 3DMark Steel Nomad. The RTX 5090's average is dragged down by low Passmark scores in legacy API tests, such as 185 in DirectX 12 and 226 in DirectX 10, which are not directly comparable to the Geekbench workloads. Looking only at the shared Geekbench tests, the RTX 5090's lead is clear and consistent. The delta percentages from the head-to-head table, negative from the perspective of the RTX 4000 SFF Ada Generation, quantify the deficit precisely: minus 62.7 percent in OpenCL and minus 71 percent in Vulkan.

Percentile placement against all GPUs in the database shows a curious inversion. The RTX 4000 SFF Ada Generation sits at the 95th percentile, while the RTX 5090 sits at the 92nd percentile. This does not mean the RTX 4000 SFF Ada is faster overall; it reflects the different benchmark distributions each card participates in. The workstation card's two Geekbench scores are both strong compute results, placing it high relative to the entire GPU population. The RTX 5090's broader test portfolio includes several low-scoring legacy DirectX entries, which pull its aggregate percentile down despite its dominant Geekbench numbers. The nearest rivals for each card tell a similar story. The RTX 4000 SFF Ada Generation trails the NVIDIA GB10 by 0.3 percent, trails the AMD Radeon PRO W7700 by 1.6 percent, beats the NVIDIA Tesla V100 SXM2 16 GB by 2.4 percent, and beats the NVIDIA RTX A5500 Mobile by 2.8 percent. The RTX 5090, by contrast, is nearly tied with the NVIDIA Tesla P100 PCIe 16 GB at plus 0.3 percent, plus 0.6 percent against the Tesla P100 PCIe 12 GB, plus 1.1 percent against the AMD Radeon RX 6850M XT, and minus 1.4 percent against the AMD Radeon Pro Vega 64X. These rival clusters show that the RTX 4000 SFF Ada Generation competes in a workstation compute tier, while the RTX 5090's average is benchmarked against a mixed set of older and mobile parts.

Where Each One Wins

The RTX 5090 wins every shared benchmark, so the use-case split is defined by magnitude and context rather than by any reversal of results. In OpenCL compute, the RTX 5090's 334,370 score versus 124,812 represents more than 2.6 times the raw output. In Vulkan, the gap widens further to over 3.4 times the RTX 4000 SFF Ada's score. For workloads that rely on Vulkan compute or modern graphics APIs, the RTX 5090 is the dominant choice by a wide margin. The RTX 4000 SFF Ada Generation does not win a single recorded test, so there is no benchmark category in the database where it outpaces the RTX 5090.

However, the RTX 4000 SFF Ada Generation's strength lies outside the raw score comparison. Its 95th percentile placement, higher than the RTX 5090's 92nd, indicates that its two Geekbench results are exceptionally strong relative to the broader GPU population. The card also carries a 70 W TDP and requires no power connectors, with a suggested PSU of 250 W. The RTX 5090 draws 575 W and requires a 16-pin connector plus a 950 W suggested PSU. In constrained environments, such as small-form-factor workstations where power delivery and thermal envelope are limited, the RTX 4000 SFF Ada Generation is the only viable option between the two. Its 168 mm length and 69 mm height fit into compact chassis, whereas the RTX 5090 measures 304 mm by 137 mm by 40 mm. The RTX 4000 SFF Ada Generation also outputs through four mini-DisplayPort 1.4a connectors, suitable for multi-display workstation setups, while the RTX 5090 provides one HDMI 2.1b and three DisplayPort 2.1b outputs.

The memory configuration further separates their intended roles. The RTX 4000 SFF Ada Generation offers 20 GB of GDDR6 on a 160-bit bus, delivering 280.0 GB/s of bandwidth. The RTX 5090 offers 32 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s. The RTX 5090's memory subsystem is vastly faster and larger, which benefits large datasets and high-resolution textures. The RTX 4000 SFF Ada Generation's 20 GB is still substantial for professional workloads, and its lower power draw makes it suitable for dense multi-GPU racks or quiet workstation builds.

Architecture Differences

The two cards come from different NVIDIA architectures and chip generations. The RTX 4000 SFF Ada Generation uses the AD104 chip built on Ada Lovelace architecture, while the RTX 5090 uses the GB202 chip built on Blackwell 2.0. Both are fabricated by TSMC on a 5 nm process node. The transistor counts differ enormously: the AD104 packs 35,800 million transistors on a 294 mm² die, while the GB202 packs 92,200 million transistors on a 750 mm² die. Transistor density is nearly identical, at 121.8 million per mm² for the AD104 and 122.9 million per mm² for the GB202, meaning the RTX 5090's advantage comes primarily from its much larger die rather than from a denser process.

The compute resources scale accordingly. The RTX 4000 SFF Ada Generation has 6,144 shading units, 192 texture mapping units, 64 render output units, 48 ray tracing cores, and 192 tensor cores. The RTX 5090 has 21,760 shading units, 680 TMUs, 176 ROPs, 170 ray tracing cores, and 680 tensor cores. In every category, the RTX 5090 has substantially more hardware. The FP32 throughput reflects this: 19.17 TFLOPS for the RTX 4000 SFF Ada Generation versus 104.8 TFLOPS for the RTX 5090. Both cards list FP16 at a 1:1 ratio with FP32, so the half-precision figures mirror those numbers. Pixel rate and texture rate follow the same pattern, with the RTX 5090 reaching 423.6 GPixel/s and 1,636.8 GTexel/s against 99.84 GPixel/s and 299.5 GTexel/s for the RTX 4000 SFF Ada Generation.

Clock speeds present an interesting divergence. The RTX 4000 SFF Ada Generation has a base clock of 720 MHz and a boost clock of 1560 MHz, while the RTX 5090 runs at a base of 2017 MHz and a boost of 2407 MHz. The RTX 5090's boost clock is more than 800 MHz higher, which compounds its compute resource advantage. Memory clocks are both listed at 1750 MHz, but the effective data rates differ: 14 Gbps for the GDDR6 on the RTX 4000 SFF Ada Generation and 28 Gbps for the GDDR7 on the RTX 5090. The bus width difference, 160-bit versus 512-bit, combines with the memory type to produce the bandwidth gap.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interfaces differ: PCIe 4.0 x16 for the RTX 4000 SFF Ada Generation versus PCIe 5.0 x16 for the RTX 5090. The release dates are also far apart, with the RTX 4000 SFF Ada Generation launching on 2023-03-20 and the RTX 5090 on 2025-01-29. The RTX 4000 SFF Ada Generation's predecessor is listed as Workstation Ampere and its successor as Blackwell PRO W, while the RTX 5090's predecessor is GeForce 40 and its successor is GeForce 60.

The Verdict

The data points to a clear performance hierarchy: the RTX 5090 is the faster card in every shared benchmark, and by a wide margin. Its OpenCL score is 62.7 percent higher and its Vulkan score is 71 percent higher. For anyone prioritizing raw compute, the RTX 5090 is the choice. Its 104.8 TFLOPS of FP32 throughput, 32 GB of GDDR7 memory, and 1.79 TB/s bandwidth place it in an entirely different performance class. The RTX 4000 SFF Ada Generation, with 19.17 TFLOPS and 280.0 GB/s, cannot match those figures in any scenario recorded in the database.

The RTX 4000 SFF Ada Generation justifies its existence through efficiency and form factor. Its 70 W TDP, no power connector requirement, 250 W suggested PSU, and compact dimensions make it suitable for systems where the RTX 5090's 575 W draw, 16-pin connector, 950 W suggested PSU, and 304 mm length would be impossible to accommodate. The workstation card also holds a higher percentile placement at 95 versus 92, indicating excellent performance relative to its power envelope. Buyers with power constraints or small chassis should pick the RTX 4000 SFF Ada Generation. Buyers with no such constraints and a need for maximum compute should pick the RTX 5090.

The launch MSRP of the RTX 5090 is 1,999 USD. The RTX 4000 SFF Ada Generation has no listed launch MSRP in the database.
