AMD Radeon RX 7700 XT vs NVIDIA RTX A4000 Mobile Comparison

The AMD Radeon RX 7700 XT and NVIDIA RTX A4000 Mobile represent two fundamentally different design philosophies: a desktop-first gaming GPU against a mobile workstation part. Benchmark data shows the RX 7700 XT winning 8 of 9 head-to-head comparisons, with an average benchmark score of 22549 against the A4000 Mobile’s 21379. The A4000 Mobile does hold one significant victory in Vulkan compute, but the overall performance delta favors the AMD part by a wide margin across most legacy and modern DirectX workloads.

Head-to-Head Benchmarks

The most lopsided result comes from Passmark’s GPU compute test, where the RX 7700 XT scores 12912 against the A4000 Mobile’s 6394, a 101.9% advantage. This is the only test where the AMD card more than doubles the NVIDIA part’s output, and it speaks to the raw throughput advantage of the Navi 32 chip. The gap narrows somewhat in the Passmark G3D test, but the RX 7700 XT still leads 22547 to 14796, a 52.4% margin. That G3D result is particularly telling because it is a synthetic aggregate of gaming-oriented workloads, and the RX 7700 XT’s lead here is consistent with its desktop positioning.

In DirectX 11, the RX 7700 XT wins 232 to 127, an 82.7% lead, while in DirectX 9 the margin is nearly identical at 87.3% (294 vs 157). These legacy API results show that the AMD architecture does not sacrifice older API performance for modern feature support. The DirectX 12 test is closer, 79 vs 66, but still a 19.7% win for the RX 7700 XT. The DirectX 10 result is the tightest of the bunch at 13.3% (119 vs 105), suggesting that the A4000 Mobile’s Ampere architecture retains some competitiveness in that specific workload.

The 2D performance gap is stark: the RX 7700 XT scores 1161 in Passmark G2D versus 585 for the A4000 Mobile, a 98.5% difference. This is likely a function of the desktop card’s dedicated display outputs and higher memory bandwidth, though the exact cause is not in the data. In Geekbench OpenCL, the RX 7700 XT leads 138383 to 97178, a 42.4% advantage. The A4000 Mobile’s only win comes in Geekbench Vulkan, where it scores 73002 against the RX 7700 XT’s 46443, a 36.4% margin in NVIDIA’s favor. This is a notable outlier, as the Vulkan result is the only benchmark where the NVIDIA part demonstrates clear superiority.

Architecture Differences

The two GPUs are built on entirely different process nodes and architectures. The RX 7700 XT uses AMD’s RDNA 3.0 architecture on a 5 nm TSMC process, with 28,100 million transistors packed into a 346 mm² die, yielding a transistor density of 81.2M per mm². The A4000 Mobile uses NVIDIA’s Ampere architecture on an 8 nm Samsung process, with 17,400 million transistors on a larger 392 mm² die, giving a much lower density of 44.4M per mm². The RX 7700 XT’s smaller die and higher density reflect a more modern manufacturing process, which contributes to its higher clock speeds: base 1435 MHz, boost 2544 MHz, and game clock 2171 MHz, versus the A4000 Mobile’s 1140 MHz base and 1680 MHz boost.

Memory configurations diverge significantly. The RX 7700 XT has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s bandwidth. The A4000 Mobile has 8 GB of GDDR6 on a 256-bit bus, yielding 384.0 GB/s. Despite the narrower bus, the AMD card’s higher memory clock (2250 MHz, 18 Gbps effective) allows it to exceed the NVIDIA part’s bandwidth. The RX 7700 XT also has more texture mapping units (216 vs 160) and more ROPs (96 vs 80), but the A4000 Mobile has more shading units (5120 vs 3456) and includes 160 tensor cores, which the AMD part lacks entirely. Both have ray tracing cores: 54 on the RX 7700 XT versus 40 on the A4000 Mobile.

The compute output reflects these architectural differences. The RX 7700 XT delivers 35.17 TFLOPS FP32 and FP16 (1:1), while the A4000 Mobile manages 17.20 TFLOPS in both. Pixel and texture rates also favor AMD: 244.2 GPixel/s and 549.5 GTexel/s versus 134.4 GPixel/s and 268.8 GTexel/s. Power consumption is another major split: the RX 7700 XT is rated at 245 W with dual-slot cooling and 2x 8-pin connectors, while the A4000 Mobile is a 115 W part with no power connectors, designed for portable devices. The RX 7700 XT suggests a 550 W PSU, while the A4000 Mobile has no such recommendation.

Where Each One Wins

The AMD Radeon RX 7700 XT is the clear winner for compute-intensive and gaming workloads. Its 101.9% lead in Passmark GPU compute and 52.4% lead in Passmark G3D make it the superior choice for tasks that rely on raw FP32 throughput. The 42.4% advantage in Geekbench OpenCL reinforces this, as does the 82.7% lead in DirectX 11 and 87.3% in DirectX 9. For users prioritizing legacy API performance, the RX 7700 XT is the stronger option. Its 98.5% lead in Passmark G2D also suggests better 2D acceleration, which benefits desktop environments and non-3D applications. With 12 GB of memory and higher bandwidth, the RX 7700 XT is better suited for modern titles that consume more video memory.

The NVIDIA RTX A4000 Mobile’s strengths are narrower but real. Its 36.4% win in Geekbench Vulkan indicates that in Vulkan-based applications, it can outperform the AMD card by a significant margin. The 160 tensor cores give it dedicated AI acceleration hardware that the RX 7700 XT lacks, making it potentially more efficient for workloads that leverage Tensor Cores. The lower 115 W TDP and absence of power connectors mean it is designed for mobile workstations where power efficiency is critical, and it can operate in form factors where the dual-slot, 245 W RX 7700 XT is physically impossible. The A4000 Mobile’s 256-bit bus, despite lower bandwidth, provides a wider path that may benefit certain memory access patterns. For users who specifically need Vulkan performance or tensor core functionality in a portable chassis, the A4000 Mobile is the relevant choice, but the data shows the RX 7700 XT wins the vast majority of benchmark comparisons.
