AMD Radeon RX 7900 XTX vs NVIDIA GeForce RTX 2080 Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between the two cards across the ten benchmark tests, with the AMD Radeon RX 7900 XTX taking 8 wins and the NVIDIA GeForce RTX 2080 taking 2. The most dramatic margin belongs to AMD in the 3DMark Steel Nomad DX12 test, where it scores 6841 against the RTX 2080's 1752. That represents a delta of -74.4% from AMD's perspective, meaning the RTX 2080 trails by nearly three-quarters of the AMD score. This is a generational gap in raw rasterization throughput, and it is the single largest performance gap in the entire comparison.

AMD also dominates the DirectX API tests. In PassMark DirectX 11, the RX 7900 XTX scores 356 versus 158 for the RTX 2080, a delta of -55.6%. In DirectX 12, the AMD card scores 131 against 72, a delta of -45%. Even in older APIs, the AMD card holds a solid lead: DirectX 10 shows 166 versus 136 (-18.1%), and DirectX 9 shows 330 versus 223 (-32.4%). The RX 7900 XTX also wins the PassMark G3D test, scoring 31238 against 18720, a delta of -40.1%. Its PassMark GPU compute score is 17689 versus 7872, a delta of -55.5%. Even the 2D graphics test, PassMark G2D, goes to AMD: 1267 versus 907, a delta of -28.4%.

The RTX 2080, however, posts two significant wins that are not close. In Geekbench OpenCL, it scores 91313 versus 50465 for the RX 7900 XTX, a delta of 80.9% in NVIDIA's favor. That is a massive margin, nearly double the AMD card's score. In Geekbench Vulkan, the RTX 2080 scores 107797 versus 85612, a delta of 25.9%. These are the only two tests NVIDIA wins, but they are decisive in raw numbers.

Interpreting the data, the RX 7900 XTX is overwhelmingly faster in traditional gaming and compute workloads, while the RTX 2080 shows surprising strength in specific OpenCL and Vulkan synthetic workloads. It is importantly the average benchmark scores in the database put the RTX 2080 at 22895, which is higher than the RX 7900 XTX's 19410, despite the RX 7900 XTX winning most individual tests. This is because the two Geekbench wins for the RTX 2080 are heavily weighted in the average, pulling its aggregate score above the AMD card. The percentile ranks also differ: the RTX 2080 sits at the 68th percentile of all GPUs, while the RX 7900 XTX sits at the 64th percentile. This is a reminder that an average score can be misleading when one card has extreme wins and losses.

Where Each One Wins

The AMD Radeon RX 7900 XTX is the clear winner for anything involving modern graphics APIs and high-resolution rasterization. It wins every PassMark DirectX test (9, 10, 11, 12), which covers legacy and current gaming workloads. It also wins the PassMark G3D and GPU Compute tests, which are general-purpose metrics for graphics performance and compute throughput. The 3DMark Steel Nomad DX12 test, a forward-looking DX12 benchmark, is an absolute blowout in AMD's favor. For any user running games that rely on DX11 or DX12, or for any compute workload that scales with shading units, the RX 7900 XTX is the superior card based on the recorded data.

The NVIDIA GeForce RTX 2080 wins in two specific areas: Geekbench OpenCL and Geekbench Vulkan. The OpenCL win is especially striking, with a delta of 80.9% over the AMD card. This suggests that the RTX 2080 has an advantage in certain OpenCL-based compute workloads, such as some content creation or scientific applications. The Vulkan win is also significant at 25.9%, which could benefit users running Vulkan-based titles or applications. However, these wins do not extend to the PassMark suite, where the AMD card dominates across the board. So, the RTX 2080 is a niche winner for specific compute and API scenarios, while the RX 7900 XTX is the broader and more consistent performer for gaming and general compute.

Specification Differences

The two cards differ on nearly every core specification. The memory configuration is a major gap: the RX 7900 XTX has 24 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. The RTX 2080 has 8 GB of GDDR6 memory on a 256-bit bus, delivering 448.0 GB/s. That is 3x the memory capacity and over twice the bandwidth for the AMD card. The clocks also differ: the RTX 2080 has a base clock of 1515 MHz and a boost of 1710 MHz, while the RX 7900 XTX has a base of 1929 MHz, a boost of 2498 MHz, and a game clock of 2365 MHz. The memory clock is also higher on the AMD card at 2500 MHz (20 Gbps effective) versus 1750 MHz (14 Gbps effective).

The compute resources are also dissimilar. The RX 7900 XTX has 6144 shading units, 384 TMUs, and 192 ROPs. The RTX 2080 has 2944 shading units, 184 TMUs, and 64 ROPs. The pixel rate is 479.6 GPixel/s for the AMD card versus 109.4 GPixel/s for the NVIDIA card. The texture rate is 959.2 GTexel/s versus 314.6 GTexel/s. In raw FP32 and FP16 throughput, the RX 7900 XTX achieves 61.39 TFLOPS and 122.8 TFLOPS, respectively, while the RTX 2080 achieves 10.07 TFLOPS and 20.14 TFLOPS.

Power and physical dimensions also differ. The RTX 2080 has a TDP of 215 W and requires a 550 W PSU, while the RX 7900 XTX has a TDP of 355 W and requires a 750 W PSU. The RTX 2080 uses a 1x 6-pin + 1x 8-pin power connector, while the RX 7900 XTX uses 2x 8-pin. The cards are both dual-slot, but the RTX 2080 is 267 mm long, 116 mm high, and 35 mm wide, while the RX 7900 XTX is 287 mm long, 110 mm high, and 51 mm wide. The bus interface is also different: PCIe 3.0 x16 for the RTX 2080, and PCIe 4.0 x16 for the RX 7900 XTX. Display outputs differ: the RTX 2080 has 1x HDMI 2.0 and 3x DisplayPort 1.4a, while the RX 7900 XTX has 1x HDMI 2.1a and 2x DisplayPort 2.1, both with a USB Type-C port.

Architecture Differences

The architecture generations are entirely different. The RTX 2080 is built on NVIDIA's Turing architecture, using the TU104 chip, fabricated on a 12 nm process at TSMC. It has 13,600 million transistors on a 545 mm² die, giving a transistor density of 25.0M per mm². The RTX 2080 includes 46 RT cores and 368 tensor cores, reflecting Turing's focus on ray tracing and AI acceleration.

The RX 7900 XTX is built on AMD's RDNA 3.0 architecture, using the Navi 31 chip (codename "Plum Bonito"). It is fabricated on a 5 nm process at TSMC, with 57,700 million transistors on a 529 mm² die, giving a transistor density of 109.1M per mm². This is a much denser and more modern process. The AMD card has 96 ray tracing cores, but no tensor cores listed. The RTX 2080 has no tensor core count listed for the RX 7900 XTX, but the AMD card has 96 RT cores versus 46 for NVIDIA. The architectures also differ in their API support: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so that is not a differentiator.

The launch dates and successors are also different. The RTX 2080 was released on 2018-09-19, with a predecessor of GeForce 10 and a successor of GeForce 30. The RX 7900 XTX was released on 2022-11-02, with a predecessor of Navi II and a successor of Navi IV. Both are end-of-life production status.

The Verdict

The data points to a straightforward conclusion for modern gaming: the AMD Radeon RX 7900 XTX is the overwhelmingly faster card in the majority of benchmarks. It wins all DirectX tests, the G3D test, the GPU compute test, and the modern 3DMark test, with deltas ranging from -18.1% to -74.4% in its favor. For any user running games that use DirectX 11 or DirectX 12, the RX 7900 XTX is the clear choice. Its massive 24 GB memory and 960.0 GB/s bandwidth also make it more capable of handling large textures and high-resolution workloads, though the database does not directly test those scenarios.

The NVIDIA GeForce RTX 2080 is not without merit. Its wins in Geekbench OpenCL and Geekbench Vulkan, with deltas of +80.9% and +25.9%, respectively, suggest that it is a better choice for specific compute workloads that use OpenCL or Vulkan APIs. The average benchmark score also favors the RTX 2080, but that is heavily influenced by its two extreme wins. The RTX 2080 also has a higher percentile rank (68th vs 64th), but this is a statistical artifact of the average score, not an indication of overall superiority.

For a user prioritizing gaming performance across modern APIs, the RX 7900 XTX is the only choice based on the recorded data. For a user with specific OpenCL or Vulkan compute needs, the RTX 2080 offers a unique advantage that cannot be ignored. The rest of the hardware specifications confirm the gap: the RX 7900 XTX has more shading units, more ROPs, more memory, and far higher bandwidth. The RTX 2080 is a capable card, but it is a generation behind in manufacturing technology and raw throughput. The verdict is simple: the RX 7900 XTX is the better performer in almost every measurable benchmark, and the RTX 2080 is a niche winner for specific compute APIs.
