AMD Radeon RX 6800M vs NVIDIA GeForce GTX 780 Ti Comparison

Where Each One Wins

The benchmark data splits cleanly along generational and architectural lines. The AMD Radeon RX 6800M wins every recorded head-to-head comparison, and the margins are substantial in all three compute-oriented tests. The NVIDIA GeForce GTX 780 Ti does not secure a single win in the shared benchmark set, which means the use-case split is defined by the AMD card's dominance rather than by complementary strengths.

The RX 6800M's largest advantage comes in the Metal API test, where it scores 113721 against the GTX 780 Ti's 18144. That is a 526.8% delta, the widest gap in the dataset. This is not a narrow win; it is a generational chasm. The AMD card also leads heavily in Vulkan, posting 94766 versus 27238, a 247.9% advantage. OpenCL shows a 220.7% lead, with the RX 6800M scoring 87621 against 27326. Every benchmark where both cards have recorded scores favors the newer AMD part.

For the GTX 780 Ti, the recorded data is limited to three Geekbench compute tests. It has no entries in the Passmark suite, no 3DMark Steel Nomad result, and no DirectX-specific scores. This means the older card's profile is incomplete relative to the RX 6800M, which has a full complement of Passmark tests plus a 3DMark result. The RX 6800M's Passmark G3D score of 13261 and its 3DMark Steel Nomad score of 2238 further illustrate its wider benchmark coverage, though those tests lack a direct GTX 780 Ti comparison.

The percentile rankings reinforce the same story. The RX 6800M sits at the 74th percentile among all GPUs in the database, while the GTX 780 Ti sits at the 70th. Both are above average, but the AMD card is positioned higher. The average benchmark score also favors the RX 6800M: 28874 versus 24236. That is a 19.1% advantage in aggregate performance, which is consistent with the individual test deltas.

The nearest rivals for each card are instructive. The RX 6800M's closest neighbors include the AMD Radeon RX 570 (0.4% ahead), the AMD Radeon RX 470 (0.4% behind), the AMD Radeon R9 M295X (1% ahead), and the Intel Arc A370M (1% behind). These are all cards that cluster tightly around the RX 6800M's average score, which suggests this AMD part is not an outlier in its own generation's mid-range tier. The GTX 780 Ti's nearest rivals include the NVIDIA GeForce GTX 1630 (0.2% behind), the NVIDIA GeForce RTX 2080 SUPER (0.3% ahead), the AMD Radeon RX 6800S (0.7% ahead), and the AMD Radeon RX 6600 XT (0.8% behind). The presence of an RTX 2080 SUPER in that list is notable, as it indicates the GTX 780 Ti's average sits close to a much newer high-end card, which speaks to the old flagship's lasting compute capability in aggregate terms.

The Verdict

The data supports a clear verdict: the AMD Radeon RX 6800M is the superior card in every measured category. It wins all three head-to-head benchmarks, holds a higher percentile rank, and posts a higher average score. Anyone choosing between these two based on recorded performance should select the RX 6800M without hesitation.

The RX 6800M is the pick for users who prioritize compute performance across Metal, Vulkan, and OpenCL workloads. Its 526.8% lead in Metal is the single most decisive result in the dataset, and its 247.9% Vulkan advantage and 220.7% OpenCL advantage leave no ambiguity. The card also carries 12 GB of GDDR6 memory on a 192-bit bus with 384.0 GB/s of bandwidth, versus the GTX 780 Ti's 3 GB of GDDR5 on a 384-bit bus with 336.6 GB/s. The AMD card's memory capacity advantage is four times the NVIDIA card's, which matters for larger textures and datasets.

The GTX 780 Ti is not without a role, but that role is historical. Its 70th percentile ranking and average score of 24236 place it in the same neighborhood as much newer cards like the RTX 2080 SUPER, which is a remarkable result for a 2013 flagship. The card also has a 600 W suggested PSU, which indicates it was designed for a desktop power envelope, while the RX 6800M is an integrated-format mobile part with no external power connectors. For someone building a modern system from current stock, the RX 6800M is the only rational choice. For someone cataloging legacy hardware, the GTX 780 Ti's compute scores remain a point of interest, but not a reason to choose it over the AMD card.

The production status of both cards is end-of-life, so neither is a forward-looking purchase. The RX 6800M's release date of 2021-05-30 makes it roughly eight years newer than the GTX 780 Ti's 2013-11-06 release, and that age gap is visible in every benchmark. The verdict is simple: take the RX 6800M for performance, take the GTX 780 Ti only if the target system requires a dual-slot desktop card with specific display outputs.

Head-to-Head Benchmarks

The head-to-head dataset contains three tests, all of which the RX 6800M wins by wide margins. The first is Geekbench Metal. The RX 6800M scores 113721, and the GTX 780 Ti scores 18144. The delta is 526.8%, meaning the AMD card delivers more than six times the Metal score of the NVIDIA card. This is the largest relative gap in the entire comparison and reflects the RX 6800M's modern RDNA 2.0 architecture, which is built with current API requirements in mind.

The second test is Geekbench OpenCL. The RX 6800M posts 87621, and the GTX 780 Ti posts 27326. The delta is 220.7%. This is a smaller margin than Metal but still represents a more than threefold advantage. OpenCL is a cross-platform compute API, and the RX 6800M's 12.24 TFLOPS of FP32 throughput, versus the GTX 780 Ti's 5.345 TFLOPS, explains much of the difference. The AMD card also has 2560 shading units and 160 texture mapping units, while the NVIDIA card has 2880 shading units and 240 TMUs. Despite having fewer shaders, the RX 6800M's higher clock speeds, base 2116 MHz and boost 2390 MHz, versus the GTX 780 Ti's base 875 MHz and boost 928 MHz, drive its compute lead.

The third test is Geekbench Vulkan. The RX 6800M scores 94766, and the GTX 780 Ti scores 27238. The delta is 247.9%. Vulkan is the modern low-overhead graphics API, and the RX 6800M supports Vulkan 1.4 while the GTX 780 Ti supports Vulkan 1.2.175. The AMD card's ray tracing cores, 40 of them, also give it hardware support for features the Kepler-based GTX 780 Ti cannot access, since it has no RT cores at all.

The RX 6800M's additional benchmarks, while not head-to-head, provide context. Its Passmark G3D score is 13261, its Passmark GPU Compute score is 5032, and its 3DMark Steel Nomad DX12 score is 2238. The GTX 780 Ti has no corresponding entries in the database, so direct comparison on those tests is not possible. However, the RX 6800M's DirectX 12 Ultimate support and its 12_2 feature level, versus the GTX 780 Ti's DirectX 12 (11_1), indicate a substantial gap in API feature support. The AMD card also supports 24.47 TFLOPS of FP16 via a 2:1 ratio, while the GTX 780 Ti has no recorded FP16 capability.

Architecture Differences

The two cards come from different architectural eras, and the recorded specifications reflect that. The AMD Radeon RX 6800M uses the Navi 22 chip built on RDNA 2.0 architecture, manufactured on a 7 nm process at TSMC. It contains 17,200 million transistors on a 335 mm² die, giving a transistor density of 51.3 million per square millimeter. The NVIDIA GeForce GTX 780 Ti uses the GK110B chip built on Kepler architecture, manufactured on a 28 nm process, also at TSMC. It contains 7,080 million transistors on a 561 mm² die, for a density of 12.6 million per square millimeter. The process node difference is stark: 7 nm versus 28 nm, and the RX 6800M packs more than twice the transistors into a smaller die.

The clock behavior also differs significantly. The RX 6800M has a base clock of 2116 MHz, a boost clock of 2390 MHz, and a game clock of 2300 MHz. Its memory runs at 2000 MHz with 16 Gbps effective speed. The GTX 780 Ti has a base clock of 875 MHz and a boost clock of 928 MHz, with memory at 1753 MHz and 7 Gbps effective. The RX 6800M's boost clock is more than 2.5 times the GTX 780 Ti's boost clock, which contributes heavily to its compute throughput advantage.

The compute resources differ in configuration. The RX 6800M has 2560 shading units, 160 TMUs, and 64 ROPs. The GTX 780 Ti has 2880 shading units, 240 TMUs, and 48 ROPs. The NVIDIA card has more shaders and TMUs, but fewer ROPs. The pixel rate tells the story: the RX 6800M achieves 153.0 GPixel/s, while the GTX 780 Ti achieves 55.68 GPixel/s. The texture rate is 382.4 GTexel/s for the AMD card versus 222.7 GTexel/s for the NVIDIA card. FP32 compute is 12.24 TFLOPS for the RX 6800M and 5.345 TFLOPS for the GTX 780 Ti. The RX 6800M also has 40 ray tracing cores, which the GTX 780 Ti lacks entirely.

Memory and power configurations diverge as well. The RX 6800M uses 12 GB of GDDR6 on a 192-bit bus, while the GTX 780 Ti uses 3 GB of GDDR5 on a 384-bit bus. Bandwidth is 384.0 GB/s for the AMD card and 336.6 GB/s for the NVIDIA card, so the narrower bus is compensated by faster memory. The RX 6800M has a TDP of 145 W and is an IGP-format part with no power connectors. The GTX 780 Ti has a TDP of 250 W, is dual-slot, requires a 1x 6-pin plus 1x 8-pin power connection, and has a suggested PSU of 600 W. The RX 6800M connects via PCIe 4.0 x16, while the GTX 780 Ti uses PCIe 3.0 x16.

API support also separates the two. The RX 6800M supports DirectX 12 Ultimate with feature level 12_2, OpenGL 4.6, and Vulkan 1.4. The GTX 780 Ti supports DirectX 12 with feature level 11_1, OpenGL 4.6, and Vulkan 1.2.175. The AMD card's display outputs are listed as portable device dependent, while the GTX 780 Ti offers 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2. The GTX 780 Ti measures 267 mm in length, 111 mm in height, and 38 mm in width. The RX 6800M has no recorded dimensions, consistent with its mobile, integrated-format design. Both cards are end-of-life, but the RX 6800M's RDNA 2.0 architecture and 2021 release date place it in a different performance and feature class than the 2013 Kepler flagship.
