AMD Radeon RX 7900 GRE vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Head-to-Head Benchmarks

The head-to-head data in the database shows a clear split between the two cards, with the AMD Radeon RX 7900 GRE taking 7 of 9 benchmark wins, while the NVIDIA GeForce RTX 5070 Ti Mobile secures 2 decisive victories. The largest margin belongs to NVIDIA in the Geekbench Vulkan test, where the RTX 5070 Ti Mobile scores 139213 against the RX 7900 GRE’s 99850, a 39.4% advantage. This result indicates a significant lead in Vulkan-based workloads, likely reflecting driver optimization and architecture efficiency for that API.

AMD’s strongest result comes in Geekbench OpenCL, where the RX 7900 GRE scores 175758 versus the RTX 5070 Ti Mobile’s 143870, a win of 18.1%. The margin here is substantial, and it points to the RX 7900 GRE’s raw compute throughput in OpenCL scenarios. The database also records a 32.7% lead for AMD in Passmark GPU Compute, with scores of 15016 versus 10101, reinforcing the pattern that AMD dominates compute-oriented tasks.

In the Passmark DirectX suite, the results are mixed but favor AMD overall. The RX 7900 GRE wins DirectX 11 by 21% (300 versus 237), DirectX 9 by 16.5% (310 versus 259), and DirectX 12 by 4.7% (107 versus 102). NVIDIA takes DirectX 10 by 8.6% (151 versus 139). The DirectX 11 margin is the largest in this group, suggesting that AMD’s architecture handles legacy DirectX workloads particularly well, while NVIDIA’s narrower DirectX 12 edge shows that the gap closes on newer APIs.

Passmark G2D and G3D results also go to AMD. The RX 7900 GRE posts a G2D score of 1180 against 981, a 16.9% lead, and a G3D score of 27089 against 24004, an 11.4% advantage. These numbers indicate that AMD has the edge in general 2D and 3D rendering tasks, though the G3D margin is modest compared to the compute and OpenCL gaps. Overall, the recorded data shows that the RTX 5070 Ti Mobile is the stronger Vulkan performer, while the RX 7900 GRE is the more consistent winner across most other tested workloads.

Architecture Differences

The two GPUs are built on fundamentally different architectures, which explains their divergent benchmark profiles. The NVIDIA GeForce RTX 5070 Ti Mobile uses the GB205 chip based on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. It contains 31,100 million transistors on a 263 mm² die, resulting in a transistor density of 118.3M per mm². In contrast, the AMD Radeon RX 7900 GRE uses the Navi 31 chip with RDNA 3.0 architecture, also on a 5 nm TSMC process, but with 57,700 million transistors spread across a 529 mm² die, yielding a lower density of 109.1M per mm². The RX 7900 GRE’s larger die and higher transistor count reflect a more compute-heavy design.

Memory configurations differ notably. NVIDIA pairs the RTX 5070 Ti Mobile with 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s of bandwidth. AMD equips the RX 7900 GRE with 16 GB of GDDR6 on a 256-bit bus, achieving 576.0 GB/s. The NVIDIA card has higher bandwidth per bit due to the faster GDDR7 memory, but AMD offers more total capacity and a wider bus. In terms of clock speeds, the RTX 5070 Ti Mobile runs at a base of 847 MHz and a boost of 1447 MHz, while the RX 7900 GRE runs at a base of 1287 MHz, a game clock of 1880 MHz, and a boost of 2245 MHz. AMD’s clocks are substantially higher across the board.

The compute unit layouts also diverge. NVIDIA’s RTX 5070 Ti Mobile has 5888 shading units, 184 TMUs, 80 ROPs, 46 RT cores, and 184 tensor cores. AMD’s RX 7900 GRE has 5120 shading units, 320 TMUs, 160 ROPs, and 80 RT cores, with no tensor cores listed. AMD’s higher TMU and ROP counts contribute to its texture and pixel rates: the RX 7900 GRE delivers 718.4 GTexel/s and 359.2 GPixel/s, while NVIDIA delivers 266.2 GTexel/s and 115.8 GPixel/s. These differences are stark and explain why AMD leads in several Passmark tests.

Compute throughput is another major differentiator. The RX 7900 GRE reaches 45.98 TFLOPS FP32 and 91.96 TFLOPS FP16 (at a 2:1 ratio), while the RTX 5070 Ti Mobile reaches 17.04 TFLOPS FP32 and 17.04 TFLOPS FP16 (at a 1:1 ratio). AMD’s FP16 output is more than five times higher, and its FP32 output is roughly 2.7 times higher. This aligns with the compute benchmark results, where AMD leads by 32.7% in Passmark GPU Compute. The RTX 5070 Ti Mobile compensates with tensor cores, which are absent from the AMD card, though the database does not provide tensor-specific benchmark results.

Power and physical design also differ. The RTX 5070 Ti Mobile is rated at 60 W TDP with an IGP slot width and no power connectors, making it a mobile-integrated solution. The RX 7900 GRE is rated at 260 W TDP, is dual-slot, requires 2x 8-pin power connectors, and has a suggested PSU of 600 W. The RX 7900 GRE also has a larger physical footprint: 276 mm length, 110 mm height, and 51 mm width, while the RTX 5070 Ti Mobile lists no dimensions. Bus interfaces differ as well, with NVIDIA using PCIe 5.0 x16 and AMD using PCIe 4.0 x16. Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data supports a straightforward choice based on workload. For users prioritizing Vulkan performance, the NVIDIA GeForce RTX 5070 Ti Mobile is the clear pick, as it outperforms the RX 7900 GRE by 39.4% in the Geekbench Vulkan test. Its 80th percentile ranking among all GPUs, versus 77th for AMD, also reflects a slightly higher overall standing in the database. However, the RTX 5070 Ti Mobile’s wins are limited to Vulkan and DirectX 10, which narrows its appeal.

For compute-heavy tasks and most DirectX workloads, the AMD Radeon RX 7900 GRE is the stronger option. It leads by 18.1% in OpenCL, 32.7% in GPU compute, and takes DirectX 11, DirectX 12, DirectX 9, G2D, and G3D tests. Its higher shading unit count in terms of raw FP32 throughput, larger memory capacity of 16 GB, and higher clock speeds all contribute to these results. The RX 7900 GRE also has a higher texture rate of 718.4 GTexel/s and pixel rate of 359.2 GPixel/s, which are more than double NVIDIA’s figures.

The verdict from the recorded data is that the RX 7900 GRE is the more versatile card for general rendering and compute, while the RTX 5070 Ti Mobile is specialized for Vulkan efficiency. Users who rely on Vulkan-based applications or who prefer NVIDIA’s ecosystem should lean toward the RTX 5070 Ti Mobile. Those who need raw compute throughput, higher memory capacity, or better legacy DirectX performance should choose the RX 7900 GRE. The average benchmark scores reinforce this: NVIDIA’s 35435 average is higher, but it is driven by the Vulkan outlier, while AMD’s 32456 average reflects more consistent performance across a wider range of tests.

Specification Differences

The two GPUs differ across nearly every specification category tracked in the database. The most prominent differences are in memory, compute, and power. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 with a 192-bit bus and 672.0 GB/s bandwidth, while the RX 7900 GRE uses 16 GB of GDDR6 with a 256-bit bus and 576.0 GB/s bandwidth. Clock speeds are higher on the AMD card: base 1287 MHz versus 847 MHz, and boost 2245 MHz versus 1447 MHz. The AMD card also lists a game clock of 1880 MHz, which the NVIDIA card does not have.

Shading units differ, with NVIDIA at 5888 and AMD at 5120, but AMD has more TMUs (320 versus 184) and more ROPs (160 versus 80). RT core counts are 46 for NVIDIA and 80 for AMD, while tensor cores exist only on NVIDIA (184). Pixel and texture rates heavily favor AMD: 359.2 GPixel/s versus 115.8 GPixel/s, and 718.4 GTexel/s versus 266.2 GTexel/s. FP32 throughput is 45.98 TFLOPS for AMD versus 17.04 TFLOPS for NVIDIA, and FP16 is 91.96 TFLOPS for AMD versus 17.04 TFLOPS for NVIDIA.

Power and physical specifications are also distinct. The RTX 5070 Ti Mobile has a 60 W TDP, IGP slot width, and no power connectors. The RX 7900 GRE has a 260 W TDP, dual-slot width, 2x 8-pin connectors, and a suggested PSU of 600 W. Bus interfaces differ, with NVIDIA using PCIe 5.0 x16 and AMD using PCIe 4.0 x16.
