AMD Radeon RX 9070 GRE vs NVIDIA GeForce RTX 3090 Ti Comparison

The NVIDIA GeForce RTX 3090 Ti and AMD Radeon RX 9070 GRE occupy different corners of the GPU landscape: the RTX 3090 Ti is an end-of-life Ampere flagship built on Samsung's 8 nm process, while the RX 9070 GRE is an active RDNA 4.0 part fabricated on TSMC's 4 nm node. Their benchmark overlap is minimal—only a single shared test—but the available data reveals a sharp contrast in compute throughput, power efficiency, and memory configuration. This analysis draws exclusively from the provided benchmark scores, specification fields, and nearest-rival comparisons.

Head-to-Head Benchmarks

The only direct head-to-head test is Geekbench OpenCL, where the RTX 3090 Ti scores 205,978 against the RX 9070 GRE's 134,417. That is a 53.2% delta in favor of the NVIDIA card—a decisive margin in raw OpenCL compute. The RTX 3090 Ti also posts a Geekbench Vulkan score of 184,015 and a 3DMark Steel Nomad DX12 result of 5,741, but the RX 9070 GRE has no corresponding entries, so those figures cannot be compared directly.

Average benchmark scores tell a different story. The RTX 3090 Ti's average is 131,911, while the RX 9070 GRE averages 134,417. From the RTX 3090 Ti's perspective, the RX 9070 GRE is 1.9% faster; from the RX 9070 GRE's side, the RTX 3090 Ti is 1.9% slower. This discrepancy arises because the RTX 3090 Ti's average incorporates three tests, including the Vulkan and Steel Nomad runs, whereas the RX 9070 GRE's average is based solely on its OpenCL result. The single head-to-head win for the RTX 3090 Ti is offset by the RX 9070 GRE's higher aggregate score.

Nearest-rival data places both GPUs within a narrow band. For the RTX 3090 Ti, the RX 9070 GRE is 1.9% faster, while the NVIDIA RTX 4000 Ada Generation is 2.4% faster and the AMD Radeon PRO W6800 is 1.3% faster. The NVIDIA L4 trails by 2.5%. For the RX 9070 GRE, the RTX 4000 Ada Generation is 0.6% faster, the NVIDIA A10M is 0.6% faster, and the Radeon PRO W6800 is 0.6% slower. The RTX 3090 Ti is 1.9% slower than the RX 9070 GRE. These deltas are small, but the RTX 3090 Ti's 53.2% OpenCL lead over the RX 9070 GRE is an outlier that does not appear in the average-based comparisons.

The Verdict

The data presents a split decision. If the sole criterion is the shared Geekbench OpenCL benchmark, the RTX 3090 Ti is the clear winner, outperforming the RX 9070 GRE by 53.2%. However, the RX 9070 GRE holds a 1.9% higher average benchmark score, despite being tested on only one workload. The RX 9070 GRE also achieves this with a TDP of 220 W versus 450 W for the RTX 3090 Ti, and it is an active product with a newer architecture (RDNA 4.0 on 4 nm) compared to the end-of-life Ampere part on 8 nm.

For users who prioritize raw OpenCL compute throughput, the RTX 3090 Ti is the stronger choice based on the head-to-head result. For those seeking a current-generation GPU with a higher average score and significantly lower power draw, the RX 9070 GRE is more compelling. The RTX 3090 Ti's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth dwarf the RX 9070 GRE's 12 GB GDDR6 at 432.0 GB/s, but the RX 9070 GRE counters with a higher boost clock (2790 MHz vs 1860 MHz) and a more dense transistor layout (151.0M / mm² vs 45.1M / mm²). The verdict hinges on workload: the RTX 3090 Ti wins the only direct test, while the RX 9070 GRE leads in aggregate score and efficiency.

Specification Differences

The two GPUs differ in nearly every physical and electrical specification. The RTX 3090 Ti is built on Samsung's 8 nm process with 28,300 million transistors on a 628 mm² die, giving a density of 45.1M / mm². The RX 9070 GRE uses TSMC's 4 nm node with 53,900 million transistors on a 357 mm² die, achieving 151.0M / mm². Clock speeds diverge: base clocks are 1560 MHz (RTX) versus 1420 MHz (RX), boost clocks are 1860 MHz versus 2790 MHz, and the RX adds a game clock of 2220 MHz (the RTX has none). Memory clocks differ as well: 1313 MHz / 21 Gbps effective for the RTX versus 2250 MHz / 18 Gbps effective for the RX.

Memory size, type, bus width, and bandwidth are all different: 24 GB GDDR6X on a 384-bit bus with 1.01 TB/s versus 12 GB GDDR6 on a 192-bit bus with 432.0 GB/s. Compute resources: the RTX has 10,752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores; the RX has 3,072 shading units, 192 TMUs, 96 ROPs, and 48 RT cores, with no tensor cores listed. Pixel rate is 208.3 GPixel/s for the RTX versus 267.8 GPixel/s for the RX; texture rate is 625.0 GTexel/s versus 535.7 GTexel/s. FP32 performance is 40.00 TFLOPS versus 34.28 TFLOPS, while FP16 is 40.00 TFLOPS (1:1) versus 68.57 TFLOPS (2:1).

Power and physical dimensions: TDP 450 W versus 220 W, slot width triple-slot versus dual-slot, power connectors 1x 16-pin versus 2x 8-pin, suggested PSU 850 W versus 550 W. Bus interface is PCIe 4.0 x16 versus PCIe 5.0 x16. Display outputs: 1x HDMI 2.1 and 3x DisplayPort 1.4a versus 1x HDMI 2.1b and 3x DisplayPort 2.1a. The RTX 3090 Ti has listed dimensions (336 mm length, 140 mm height, 61 mm width); the RX 9070 GRE has no dimensions provided. Production status is end-of-life versus active. Release dates are 2022-01-26 for the RTX and 2025-05-07 for the RX. The RTX has a predecessor (GeForce 20) and successor (GeForce 40); the RX lists a predecessor (Navi III) and no successor. The RTX 3090 Ti has a launch MSRP of 1,999 USD; the RX 9070 GRE has no launch MSRP field.

Architecture Differences

The architectural gap is fundamental. The RTX 3090 Ti uses the GA102 chip under the Ampere architecture, while the RX 9070 GRE uses the Navi 48 chip under RDNA 4.0. The process node shifts from Samsung 8 nm to TSMC 4 nm, and the foundry changes accordingly. Transistor density is more than three times higher on the RX (151.0M / mm² vs 45.1M / mm²), despite the RX having a smaller die (357 mm² vs 628 mm²) and more total transistors (53,900M vs 28,300M).

Compute architecture differs markedly: the RTX 3090 Ti has 336 tensor cores and a 1:1 FP16 ratio, whereas the RX 9070 GRE has no tensor cores and a 2:1 FP16 ratio (68.57 TFLOPS vs 40.00 TFLOPS). The RTX has far more shading units (10,752 vs 3,072) and TMUs (336 vs 192), but the RX has a higher pixel rate (267.8 GPixel/s vs 208.3 GPixel/s) despite fewer ROPs (96 vs 112). The RX's higher boost clock (2790 MHz vs 1860 MHz) partially compensates for its smaller compute array.

Memory architecture is also distinct: GDDR6X with a 384-bit bus versus GDDR6 with a 192-bit bus. The RTX offers 1.01 TB/s bandwidth, more than double the RX's 432.0 GB/s. Power delivery and cooling reflect these differences—the RTX requires a triple-slot cooler, a 16-pin connector, and an 850 W PSU, while the RX fits a dual-slot design with two 8-pin connectors and a 550 W PSU. The RX supports PCIe 5.0, a generation newer than the RTX's PCIe 4.0. Display output standards also differ: the RX includes HDMI 2.1b and DisplayPort 2.1a, whereas the RTX has HDMI 2.1 and DisplayPort 1.4a. These architectural choices explain the performance and efficiency profile observed in the benchmark data.
