NVIDIA GeForce RTX 3090 Ti vs NVIDIA GeForce RTX 4090 D Comparison

NVIDIA’s GeForce RTX 4090 D and GeForce RTX 3090 Ti represent two distinct eras of flagship graphics. The data shows a clear generational leap, with the RTX 4090 D winning all three head-to-head benchmarks decisively. However, the comparison is not merely about raw speed; it also highlights fundamental architectural shifts, efficiency improvements, and differing performance profiles across compute and gaming workloads. This analysis breaks down where each card excels, the architectural reasons behind those differences, and the specific benchmark numbers that quantify the gap.

Where Each One Wins

The RTX 4090 D is the outright winner across every benchmark in the dataset, but the magnitude of its victories varies significantly by workload type. Its most dominant performance appears in compute-heavy tasks, specifically Geekbench OpenCL, where it scores 278,621 against the RTX 3090 Ti’s 174,441—a 59.7% advantage. This suggests the Ada Lovelace architecture provides a substantial uplift in general-purpose compute and parallel processing workloads, likely benefiting professional applications, rendering tasks, and non-gaming compute.

In contrast, the RTX 4090 D’s smallest win comes in the Geekbench Vulkan test, where it scores 246,941 versus 215,633, a 14.5% lead. Vulkan is a low-level graphics API that can be more sensitive to driver overhead and raw throughput; while the RTX 4090 D still wins, the narrower margin suggests that Ampere’s architecture remains competitive in certain graphics-centric scenarios. The 3DMark Steel Nomad DX12 test sits in between, with the RTX 4090 D scoring 8,587 against 5,741, a 49.6% lead, indicating a strong but not absolute advantage in modern DirectX 12 gaming workloads. The RTX 3090 Ti’s single redeeming quality is that it achieves a respectable 95th percentile against all GPUs, but the RTX 4090 D sits higher at the 98th percentile, meaning the newer card is not just faster but also more elite relative to the entire GPU market.

Architecture Differences

The two cards are built on fundamentally different manufacturing processes and chip designs. The RTX 4090 D uses the AD102 chip on TSMC’s 5 nm process node, while the RTX 3090 Ti employs the GA102 chip on Samsung’s 8 nm node. This process shrink explains the massive difference in transistor density: the RTX 4090 D packs 76,300 million transistors into a 609 mm² die, yielding 125.3 million transistors per square millimeter, whereas the RTX 3090 Ti has 28,300 million transistors on a larger 628 mm² die, yielding just 45.1 million per square millimeter. The newer card achieves nearly three times the transistor density despite a slightly smaller physical die.

The compute resources reflect this density advantage. The RTX 4090 D features 14,592 shading units, 456 texture mapping units, and 176 raster output units, compared to the RTX 3090 Ti’s 10,752 shading units, 336 TMUs, and 112 ROPs. The ray tracing and AI acceleration hardware also scales: the RTX 4090 D has 114 RT cores and 456 tensor cores, versus 84 RT cores and 336 tensor cores on the older card. Memory configurations are identical—24 GB of GDDR6X on a 384-bit bus with 1.01 TB/s bandwidth—but the clock speeds diverge sharply. The RTX 4090 D runs at a 2280 MHz base and 2520 MHz boost, while the RTX 3090 Ti is at 1560 MHz base and 1860 MHz boost. This clock advantage, combined with the higher core counts, drives the RTX 4090 D’s compute rates: 73.54 TFLOPS FP32 and FP16, versus 40.00 TFLOPS on the RTX 3090 Ti. Pixel and texture fill rates also favor the newer card, at 443.5 GPixel/s and 1,149.1 GTexel/s versus 208.3 GPixel/s and 625.0 GTexel/s.

Power consumption is another point of architectural contrast. The RTX 4090 D is rated at 425 W TDP with a suggested 800 W PSU, while the RTX 3090 Ti draws 450 W with a suggested 850 W PSU. Despite having substantially more compute resources, the RTX 4090 D consumes less power, highlighting the efficiency gained from the 5 nm process. Both cards are triple-slot designs with a single 16-pin power connector and identical display outputs (1x HDMI 2.1 and 3x DisplayPort 1.4a). The RTX 4090 D is shorter at 304 mm versus the RTX 3090 Ti’s 336 mm, though both are similar in height and width.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test provides the most direct gaming-oriented comparison. The RTX 4090 D scores 8,587, which is 49.6% higher than the RTX 3090 Ti’s 5,741. This is a massive generational uplift in a modern DirectX 12 rasterization workload, aligning with the RTX 4090 D’s higher shader count and clock speeds. The RTX 3090 Ti’s score places it near its nearest rival, the NVIDIA L4, which has an average score of 131,072 (0.7% difference), while the RTX 4090 D’s 8,587 situates it just 2.2% behind the NVIDIA RTX PRO 5000 Blackwell’s average score of 182,109.

In Geekbench OpenCL, the gap widens dramatically. The RTX 4090 D achieves 278,621, a 59.7% lead over the RTX 3090 Ti’s 174,441. This benchmark heavily taxes raw compute throughput, and the RTX 4090 D’s 73.54 TFLOPS FP32 capability is nearly double the RTX 3090 Ti’s 40.00 TFLOPS. The RTX 3090 Ti’s OpenCL score is close to its nearest rival, the AMD Radeon PRO W6800, which averages 135,396 (a 2.6% difference), while the RTX 4090 D’s score is only 3.1% behind the NVIDIA A100 SXM4 80 GB, which averages 183,725.

The Geekbench Vulkan test shows the smallest gap, with the RTX 4090 D scoring 246,941 versus the RTX 3090 Ti’s 215,633, a 14.5% lead. Vulkan’s lower overhead may allow the older Ampere architecture to stretch its legs, but the RTX 4090 D still holds a comfortable advantage. This result suggests that while the RTX 3090 Ti is not obsolete in Vulkan-based games or applications, it cannot match the newer card’s overall throughput. Across all three tests, the RTX 4090 D’s average benchmark score is 178,050, compared to the RTX 3090 Ti’s 131,938, a 35% overall improvement.

The Verdict

The data is unambiguous: the RTX 4090 D is the superior card in every measured benchmark. For users prioritizing raw compute performance—whether in OpenCL-heavy professional workloads, high-end 3D rendering, or general GPU compute—the RTX 4090 D offers a 59.7% advantage in Geekbench OpenCL and a 49.6% lead in 3DMark Steel Nomad, making it the clear choice. Its 98th percentile ranking against all GPUs, versus the RTX 3090 Ti’s 95th, reinforces its position as a more elite product.

However, the RTX 3090 Ti is not without merit. Its Vulkan score of 215,633 shows it remains within 14.5% of the newer card in that specific API, and its 24 GB of GDDR6X memory and 1.01 TB/s bandwidth match the RTX 4090 D exactly. For users with workloads that are memory-bandwidth-bound or that rely heavily on Vulkan, the older card may still be serviceable, especially given its lower launch MSRP of 1,999 USD versus the RTX 4090 D’s 1,599 USD—though the newer card is cheaper at launch. The RTX 3090 Ti also consumes 450 W versus 425 W, meaning the RTX 4090 D delivers more performance while drawing less power, a critical advantage for system builders. Ultimately, the RTX 4090 D wins on every metric that matters: performance, efficiency, and price. The RTX 3090 Ti is a capable card for its generation, but the data shows it is outclassed by a wide margin.
