AMD Radeon RX 7800 XT vs NVIDIA RTX A2000 Mobile Comparison

Head-to-Head Benchmarks

The most striking result in the head-to-head comparison is the Geekbench OpenCL score, where the NVIDIA RTX A2000 Mobile posts a massive 209% advantage over the AMD Radeon RX 7800 XT. The NVIDIA card scores 56518, while the AMD card manages only 18290. This is a dominant win for the mobile workstation card and suggests its compute-oriented design excels in OpenCL workloads, despite being a much smaller and lower-power part.

Every other benchmark in the comparison goes the other way. In Geekbench Vulkan, the AMD Radeon RX 7800 XT narrowly wins with a score of 54228 versus 53146, a 2% margin. That is a close call, but it establishes the AMD card as the stronger choice for Vulkan-based applications.

The Passmark suite shows a consistent and often overwhelming trend in favor of the AMD card. In DirectX 10, the RX 7800 XT scores 121 versus 57, a 52.9% lead. DirectX 11 is even more lopsided: 249 versus 68, a 72.7% gap. DirectX 12 narrows somewhat but remains decisive, with the AMD card at 93 versus 47, a 49.5% advantage. DirectX 9 sees the AMD card at 304 versus 115, a 62.2% lead. The 2D test also favors AMD heavily, with 1177 versus 491, a 58.3% difference.

The two most important overall metrics reinforce this pattern. In Passmark G3D, the RX 7800 XT scores 24176, which is 60.2% higher than the RTX A2000 Mobile's 9611. In Passmark GPU Compute, the AMD card delivers 13473 versus 4334, a 67.8% lead. The RTX A2000 Mobile wins only one of the nine head-to-head tests, but that single OpenCL result is so large that it skews the average benchmark score. The database records the RTX A2000 Mobile with an average benchmark score of 13821, while the RX 7800 XT sits at 11627. That average is heavily influenced by the OpenCL outlier.

Architecture Differences

The two cards come from fundamentally different design philosophies. The NVIDIA RTX A2000 Mobile uses the GA107 chip, built on Ampere architecture, fabricated by Samsung on an 8 nm process. It contains 8,700 million transistors on a 200 mm² die, resulting in a transistor density of 43.5M per mm². The AMD Radeon RX 7800 XT uses the Navi 32 chip, built on RDNA 3.0 architecture, fabricated by TSMC on a 5 nm process. It packs 28,100 million transistors onto a 346 mm² die, yielding a density of 81.2M per mm². The AMD chip is more than three times larger in transistor count and more than double the density per area.

The RTX A2000 Mobile has 2560 shading units, 80 texture mapping units, and 48 ROPs. It also includes 20 ray tracing cores and 80 tensor cores, which are absent from the AMD card's specification list. The RX 7800 XT has 3840 shading units, 240 TMUs, and 96 ROPs, plus 60 ray tracing cores. The AMD card has no tensor core count listed. In raw throughput, the RX 7800 XT delivers 37.32 TFLOPS of FP32 and FP16 performance, while the RTX A2000 Mobile delivers 8.637 TFLOPS in both. The AMD card's texture rate is 583.2 GTexel/s versus 135.0 GTexel/s, and its pixel rate is 233.3 GPixel/s versus 80.98 GPixel/s.

Memory configurations are vastly different. The RTX A2000 Mobile has 4 GB of GDDR6 on a 128-bit bus, achieving 192.0 GB/s. The RX 7800 XT has 16 GB of GDDR6 on a 256-bit bus, achieving 624.1 GB/s. The AMD card also supports higher memory clocks at 19.5 Gbps effective, compared to 12 Gbps effective on the NVIDIA card. Both cards support PCIe 4.0 x16 and share the same API support: DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data points to two very different products with clear use cases. The AMD Radeon RX 7800 XT is the dominant performer across nearly every benchmark in the head-to-head comparison. It wins 8 out of 9 tests, with leads ranging from 2% in Vulkan to 72.7% in DirectX 11. Its 60.2% advantage in Passmark G3D and 67.8% lead in GPU Compute make it the obvious choice for gaming, DirectX-based applications, and general compute workloads. The RX 7800 XT also has four times the memory capacity and more than three times the memory bandwidth, which matters for high-resolution textures and large datasets.

The NVIDIA RTX A2000 Mobile, however, has one extraordinary strength: Geekbench OpenCL performance. Its 56518 score is 209% higher than the AMD card's 18290. This single result is enough to give the RTX A2000 Mobile a higher average benchmark score (13821 versus 11627) and a slightly higher percentile ranking (55th versus 51st). For users whose primary workload is OpenCL-based, the RTX A2000 Mobile is the better choice despite its smaller memory and lower raw specs.

The RTX A2000 Mobile is also a mobile IGP card with a 95 W TDP and no power connectors, while the RX 7800 XT is a dual-slot desktop card with a 263 W TDP and two 8-pin connectors. The NVIDIA card is end-of-life, while the AMD card is still active. The AMD card was released later, in 2023, compared to 2021 for the NVIDIA card. The RX 7800 XT has a launch MSRP of 499 USD. These are fundamentally different products for different environments.

Where Each One Wins

The AMD Radeon RX 7800 XT wins in nearly every conventional graphics scenario. It is the clear choice for DirectX gaming, with massive leads in DirectX 9 (62.2%), DirectX 10 (52.9%), DirectX 11 (72.7%), and DirectX 12 (49.5%). Its Passmark G3D score of 24176 indicates strong overall 3D rendering capability. The GPU Compute score of 13473 also makes it suitable for general compute tasks that use OpenCL or similar frameworks. The 16 GB memory capacity and 624.1 GB/s bandwidth provide ample headroom for modern game textures and compute buffers. The 2D performance is also far better, with a 58.3% lead in Passmark G2D.

The NVIDIA RTX A2000 Mobile wins specifically in Geekbench OpenCL, where its 56518 score is 209% higher than the AMD card. This suggests specialized OpenCL workloads, such as certain scientific simulations, medical imaging, or professional compute pipelines, would see a significant advantage on the NVIDIA card. The presence of 80 tensor cores also gives it a feature that the AMD card does not list, which could be relevant for machine learning inference tasks that leverage tensor operations. Its 95 W TDP and integrated form factor make it suitable for mobile or compact systems where power and space are constrained.

For a desktop gamer or a user running a broad mix of DirectX applications, the RX 7800 XT is the obvious pick. For a professional running OpenCL-centric workloads in a mobile form factor, the RTX A2000 Mobile has a unique and measurable edge. The data does not suggest one card is universally better; it suggests they serve different masters.
