AMD Radeon RX 7900 GRE vs NVIDIA GeForce RTX 4070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall win for the AMD Radeon RX 7900 GRE, taking 8 of the 9 shared benchmarks against the NVIDIA GeForce RTX 4070 Mobile. The single exception is the Vulkan compute test, where the NVIDIA part manages a narrow victory.

The most lopsided result in the comparison is the PassMark GPU Compute test. The AMD card scores 15016 against the NVIDIA mobile GPU's 8399, a 78.8% advantage. This is the largest delta in any benchmark between the two, and it reflects a fundamental difference in raw compute throughput that shows up across the board.

In DirectX 11 workloads, the AMD card is similarly dominant. Its score of 300 versus 179 represents a 67.6% lead. This is a substantial gap that suggests the desktop part handles legacy API workloads with considerably more headroom. The DirectX 9 result follows the same pattern, with the RX 7900 GRE scoring 310 against 223, a 39% advantage.

The OpenCL benchmark also goes to AMD by a wide margin. The RX 7900 GRE posts 175758, while the RTX 4070 Mobile manages 109197, a 61% difference. This is consistent with the GPU compute result and reinforces the impression that the desktop card is in a different performance class for general-purpose compute tasks.

The 2D graphics test, PassMark G2D, shows another clear win for the AMD part. Its score of 1180 is 54.7% higher than the mobile NVIDIA card's 763. While 2D performance is rarely a bottleneck in modern gaming, the margin here is still notable.

The main gaming-oriented 3D benchmark, PassMark G3D, gives the RX 7900 GRE a 38.3% lead, with scores of 27089 and 19587 respectively. This is the most relevant result for typical gaming workloads, and the desktop card's advantage is substantial. It aligns with the overall average benchmark score, where the AMD card sits at 32456 against the NVIDIA card's 27435.

The DirectX 12 result is closer in percentage terms but still favors AMD. The RX 7900 GRE scores 107, the RTX 4070 Mobile scores 85, a 25.9% difference. DirectX 10 shows a 19.8% lead for the AMD card (139 versus 116).

The one benchmark where NVIDIA comes out ahead is Geekbench Vulkan. The RTX 4070 Mobile scores 108367, while the RX 7900 GRE scores 99850, a 7.9% deficit for AMD. This is the only test where the mobile part wins, and it is a moderate margin compared to the AMD wins elsewhere. It suggests that in Vulkan compute specifically, the Ada Lovelace architecture has an efficiency edge, but it does not translate into a broader trend.

The head-to-head table confirms the overall picture: AMD wins 8 tests, NVIDIA wins 1. The deltas range from 19.8% to 78.8% in AMD's favor, while the NVIDIA win is just 7.9%. The average benchmark scores reflect this distribution, with the RX 7900 GRE at 32456 and the RTX 4070 Mobile at 27435. The AMD card also holds a higher percentile against all GPUs, sitting at 77 compared to NVIDIA's 73.

The Verdict

The data points to a clear choice for desktop users who prioritize raw performance. The AMD Radeon RX 7900 GRE wins 8 of 9 shared benchmarks, and its average score of 32456 is 18.3% higher than the NVIDIA card's 27435. In compute-heavy workloads, the AMD part is in a different league, with a 78.8% lead in GPU compute and a 61% lead in OpenCL. For gaming, the 38.3% advantage in PassMark G3D is decisive.

The NVIDIA GeForce RTX 4070 Mobile has one thing going for it: the Geekbench Vulkan result. If the workload in question is Vulkan compute, the NVIDIA card is 7.9% ahead. That is a narrow margin, and it is the only test where the mobile part comes out on top. Outside of that specific scenario, there is no statistical support for choosing the NVIDIA card based on the recorded benchmarks.

The RTX 4070 Mobile is an integrated GPU for laptops, and its 115 W TDP reflects that. The RX 7900 GRE is a dual-slot desktop card with a 260 W TDP and two 8-pin power connectors. The performance gap is consistent with that power envelope difference. The AMD card is the choice for anyone building a desktop system where space and power are not constraints.

The NVIDIA card's only practical advantage is its form factor and the fact that it is an IGP, meaning it can be found in portable devices. If mobility is the primary requirement, the RTX 4070 Mobile exists in a category where the RX 7900 GRE cannot compete, because the desktop card has no mobile equivalent. But in a direct head-to-head comparison of benchmark scores, the AMD part is superior in almost every measurable way.

The percentile ranking supports this: the RX 7900 GRE is in the 77th percentile of all GPUs, the RTX 4070 Mobile in the 73rd. The AMD card's nearest rivals, the AMD FirePro S10000 and AMD Radeon Pro 570X, have average scores within 0.9% of it, while the NVIDIA card sits alongside the AMD Radeon RX 6700 XT and NVIDIA GeForce RTX 3090 in its performance tier. The RX 7900 GRE is simply a faster GPU.

Specification Differences

The two cards differ in nearly every hardware specification. The AMD Radeon RX 7900 GRE has 5120 shading units, 320 TMUs, and 160 ROPs. The NVIDIA GeForce RTX 4070 Mobile has 4608 shading units, 144 TMUs, and 48 ROPs. The AMD card's texture rate is 718.4 GTexel/s, while the NVIDIA card's is 244.1 GTexel/s. Pixel rates are 359.2 GPixel/s for AMD and 81.36 GPixel/s for NVIDIA.

Memory is another major differentiation point. The RX 7900 GRE has 16 GB of GDDR6 on a 256-bit bus, yielding a bandwidth of 576.0 GB/s. The RTX 4070 Mobile has 8 GB of GDDR6 on a 128-bit bus, with a bandwidth of 256.0 GB/s. The AMD card has double the memory capacity and more than double the bandwidth.

Clock speeds also differ. The AMD card has a base clock of 1287 MHz, a boost of 2245 MHz, and a game clock of 1880 MHz. The NVIDIA card has a base of 1395 MHz and a boost of 1695 MHz. The NVIDIA card's base clock is higher, but its boost clock is significantly lower.

The power profile is starkly different. The RX 7900 GRE is rated at 260 W TDP, requires a 600 W suggested PSU, and uses two 8-pin connectors. The RTX 4070 Mobile is rated at 115 W TDP, has no power connectors, and is an IGP. The NVIDIA card is a mobile part; the AMD card is a dual-slot desktop card with a length of 276 mm, a height of 110 mm, and a width of 51 mm.

The bus interface differs as well: the AMD card uses PCIe 4.0 x16, while the NVIDIA card uses PCIe 4.0 x8. Display outputs are also distinct, with the AMD card offering 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, while the NVIDIA card's outputs are listed as portable device dependent.

Architecture Differences

The architectural foundations of these two GPUs are fundamentally different. The AMD Radeon RX 7900 GRE is built on RDNA 3.0, specifically the Navi 31 chip with the codename Plum Bonito. It belongs to the Navi III (RX 7000) generation. The NVIDIA GeForce RTX 4070 Mobile uses Ada Lovelace, with the AD106 chip, and is part of the GeForce 40 Mobile generation.

Both are manufactured on a 5 nm process at TSMC, but the die sizes are very different. The AMD chip is 529 mm² with 57,700 million transistors, giving a transistor density of 109.1M per mm². The NVIDIA chip is 188 mm² with 22,900 million transistors, giving a density of 121.8M per mm². The AMD chip is nearly three times larger and has more than double the transistor count.

Ray tracing capabilities also differ. The RX 7900 GRE has 80 RT cores, while the RTX 4070 Mobile has 36. The NVIDIA card additionally has 144 tensor cores, while the AMD card has no tensor cores listed. This reflects a design difference: NVIDIA integrates dedicated tensor hardware for AI workloads, while AMD does not.

Compute throughput is another major divergence. The AMD card delivers 45.98 TFLOPS of FP32 performance and 91.96 TFLOPS of FP16 (via 2:1 ratio). The NVIDIA card delivers 15.62 TFLOPS of FP32 and 15.62 TFLOPS of FP16 (1:1 ratio). The AMD card has nearly three times the FP32 throughput and a much higher FP16 peak, but the NVIDIA card's FP16 is not a doubled rate.

The API support is identical in terms of DirectX, OpenGL, and Vulkan. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The memory type is GDDR6 for both, but the AMD card's 256-bit bus and 576.0 GB/s bandwidth are far beyond the NVIDIA card's 128-bit bus and 256.0 GB/s.

The AMD card's predecessor is Navi II, and its successor is Navi IV. The NVIDIA card's predecessor is GeForce 30 Mobile, and its successor is GeForce 50 Mobile. The release dates differ: the RX 7900 GRE was released on July 26, 2023, while the RTX 4070 Mobile was released on January 2, 2023. The AMD card has a launch MSRP of 549 USD. The NVIDIA card has no recorded launch MSRP.
