AMD Radeon RX Vega 64 vs NVIDIA GeForce RTX 5070 Ti Comparison

AMD Radeon RX Vega 64 and NVIDIA GeForce RTX 5070 Ti represent two vastly different eras of GPU design, yet the aggregate benchmark data places them in a remarkably close overall standing. The Vega 64 averages a score of 50,001 across all tests, while the RTX 5070 Ti sits at 49,957, a negligible 0.1% difference that puts the older card marginally ahead in the aggregate. Both cards occupy the 86th percentile of all GPUs, making them statistically equivalent in overall performance despite an eight-year gap in release dates and fundamental architectural shifts. The head-to-head results, however, tell a more dramatic story of generational dominance in specific workloads.

Head-to-Head Benchmarks

The RTX 5070 Ti wins all three directly comparable benchmarks, and it wins them decisively. In 3DMark Steel Nomad DX12, the NVIDIA card scores 6,604 against the Vega 64's 1,669, a 74.7% margin that represents a near-total rout. This is not a marginal improvement; the newer card delivers roughly four times the raw DX12 rasterization throughput in this specific test. The gap in compute-oriented Geekbench tests is similarly lopsided. In Geekbench OpenCL, the RTX 5070 Ti scores 212,363 versus 62,552 for the Vega 64, a 70.5% deficit for the AMD card. The Vulkan test shows the same pattern: 225,122 for NVIDIA versus 67,032 for AMD, a 70.2% shortfall.

What makes these numbers striking is the context from the nearest rivals. The RTX 5070 Ti's nearest competitor, aside from the Vega 64 itself, is the Intel Arc A550M at 49,737 (0.4% behind), while the Vega 64's closest rival is the same RTX 5070 Ti at 49,957 (0.1% behind). The AMD Radeon RX 6900 XT is 1.9% ahead of the Vega 64 and 2.0% ahead of the RTX 5070 Ti, while the RX 6800 XT trails both by 3.1%. This suggests that while the head-to-head deltas are enormous, the aggregate benchmark suite—which includes different tests for each card—paints a picture of comparable overall capability. The RTX 5070 Ti's wins are concentrated in the tests it shares with the Vega 64, where its architectural advantages become overwhelming.

Architecture Differences

The foundational difference lies in the manufacturing process and transistor budget. The Vega 64 uses a 14 nm process at GlobalFoundries, packing 12,500 million transistors into a 495 mm² die for a density of 25.3 million transistors per mm². The RTX 5070 Ti uses a 5 nm process at TSMC, fitting 45,600 million transistors into a smaller 378 mm² die, achieving a density of 120.6 million transistors per mm²—roughly 4.8 times denser. This density advantage enables the NVIDIA card to field 8,960 shading units, 280 texture mapping units, and 96 ROPs, against the Vega 64's 4,096 shaders, 256 TMUs, and 64 ROPs. The RTX 5070 Ti also adds 70 RT cores and 280 tensor cores, features entirely absent from the Vega 64's GCN 5.0 design.

Clock speeds and memory architecture further separate the two. The Vega 64 runs a 1247 MHz base and 1546 MHz boost, while the RTX 5070 Ti operates at 2295 MHz base and 2452 MHz boost—a substantial frequency advantage that compounds with the larger shader count. Memory configuration diverges sharply: the Vega 64 uses 8 GB of HBM2 on a 2048-bit bus delivering 483.8 GB/s, while the RTX 5070 Ti uses 16 GB of GDDR7 on a 256-bit bus delivering 896.0 GB/s. The NVIDIA card's bandwidth is 85% higher despite a narrower bus, thanks to faster memory clocks. The Vega 64's FP32 throughput is 12.66 TFLOPS, while the RTX 5070 Ti reaches 43.94 TFLOPS—3.5 times higher. The Vega 64 does offer FP16 at 25.33 TFLOPS via a 2:1 ratio, but the RTX 5070 Ti matches its FP32 rate at 43.94 TFLOPS with a 1:1 ratio, indicating a fundamentally different compute pipeline.

Specification Differences

The two cards differ across nearly every specification category. The Vega 64 uses a 14 nm GlobalFoundries process, while the RTX 5070 Ti uses a 5 nm TSMC process. Transistor counts are 12,500 million versus 45,600 million, with die sizes of 495 mm² versus 378 mm². Clock speeds show the RTX 5070 Ti at 2295 MHz base and 2452 MHz boost, against 1247 MHz and 1546 MHz for the Vega 64. Memory capacity is 8 GB HBM2 versus 16 GB GDDR7, with bus widths of 2048-bit versus 256-bit and bandwidth of 483.8 GB/s versus 896.0 GB/s.

Shader resources differ massively: 4,096 shading units, 256 TMUs, and 64 ROPs for AMD, versus 8,960 shaders, 280 TMUs, and 96 ROPs for NVIDIA. The RTX 5070 Ti adds 70 RT cores and 280 tensor cores; the Vega 64 has none. Pixel rate is 98.94 GPixel/s versus 235.4 GPixel/s, and texture rate is 395.8 GTexel/s versus 686.6 GTexel/s. FP32 performance is 12.66 TFLOPS versus 43.94 TFLOPS. Power draw is 295 W versus 300 W, with suggested PSUs of 600 W versus 700 W. The bus interface is PCIe 3.0 x16 for Vega 64 and PCIe 5.0 x16 for RTX 5070 Ti. Display outputs are HDMI 2.0b and DisplayPort 1.4a versus HDMI 2.1b and DisplayPort 2.1b. The Vega 64 is end-of-life, released in August 2017 at 499 USD MSRP; the RTX 5070 Ti is active, released in February 2025 at 749 USD MSRP.

The Verdict

The data shows that the RTX 5070 Ti is categorically superior in every head-to-head benchmark, with margins between 70.2% and 74.7% in its favor. Its architectural advantages—5 nm process, 3.5x FP32 throughput, double the memory capacity, and 85% more bandwidth—translate directly into massive performance wins in shared tests. The Vega 64's only claim to parity is the aggregate score, which is skewed by the fact that the two cards run different benchmark suites; the shared tests universally favor NVIDIA. The RTX 5070 Ti also offers features the Vega 64 lacks entirely, such as RT cores and tensor cores, plus newer API support including DirectX 12 Ultimate and Vulkan 1.4. For any workload represented in the head-to-head data, the RTX 5070 Ti is the clear choice. The Vega 64's 0.1% aggregate advantage is a statistical artifact, not a meaningful performance equivalence.

Where Each One Wins

The RTX 5070 Ti wins decisively in every directly comparable workload. In 3DMark Steel Nomad DX12, it scores 6,604 versus 1,669, making it the pick for modern DX12 gaming and rasterization. In Geekbench OpenCL, its 212,363 score versus 62,552 positions it as the superior choice for general-purpose compute and OpenCL-accelerated applications. In Geekbench Vulkan, its 225,122 versus 67,032 makes it the better option for Vulkan-based games and workloads. The RTX 5070 Ti also wins on memory capacity and bandwidth, making it suitable for high-resolution textures and large datasets, and its RT and tensor cores enable ray tracing and AI features that the Vega 64 cannot perform at all.

The Vega 64 has no benchmark wins in the shared test suite, so its advantages are limited to legacy contexts. It uses PCIe 3.0, which may be more compatible with older platforms, and its 295 W TDP is slightly lower than the RTX 5070 Ti's 300 W, though the suggested PSU is 100 W lower at 600 W. Its HBM2 memory on a 2048-bit bus offers a different bandwidth profile, but at half the capacity. For users constrained to older motherboards without PCIe 5.0 support, or those seeking a card with a lower PSU requirement, the Vega 64 remains functional, but the performance data offers no scenario where it outpaces the RTX 5070 Ti. The verdict is unambiguous: the RTX 5070 Ti wins every measurable performance comparison, and the Vega 64's value now rests solely on legacy compatibility and lower system power demands.
