AMD Radeon 780M vs NVIDIA TITAN Xp Comparison

Where Each One Wins

The recorded benchmark data splits cleanly into two very different profiles. The NVIDIA TITAN Xp wins every head-to-head test in the database, taking all 3 direct comparisons outright. The AMD Radeon 780M, an integrated graphics processor, does not win a single recorded benchmark against the TITAN Xp. That is an unambiguous result, but it does not mean the Radeon 780M is without purpose; it merely means its strengths lie outside the synthetic scoring metrics captured here.

The TITAN Xp is a discrete, dual-slot desktop card built on the Pascal architecture with a 250 W TDP. Its wins are overwhelming in magnitude, not marginal. In 3DMark Steel Nomad DX12, the TITAN Xp scores 2372 against 480 for the Radeon 780M, a delta of 394.2%. In Geekbench OpenCL, the TITAN Xp posts 72585 versus 18602, a 290.2% advantage. In Geekbench Vulkan, the TITAN Xp reaches 87180 while the Radeon 780M manages 33683, a 158.8% lead. These are not close contests; the TITAN Xp dominates every workload represented in the head-to-head set.

The Radeon 780M, by contrast, is a 15 W integrated GPU built on RDNA 3.0 with a 4 nm process. It has no discrete memory, relying on System Shared memory with System Dependent bandwidth. Its scores are far lower, but its entire design brief is different. The data shows the Radeon 780M still holds a 61st percentile position among all GPUs in the database, only three points behind the TITAN Xp's 64th percentile. That is a remarkably high standing for an IGP, and it indicates the Radeon 780M is not a weak part in absolute terms; it is simply outclassed by a flagship discrete card from an earlier generation.

The use-case split is therefore not about which GPU wins benchmark tests, because the TITAN Xp wins all of them. Instead, the split is about what each product is designed to do. The TITAN Xp is built for maximum throughput, with 3840 shading units, 240 TMUs, 96 ROPs, 12 GB of GDDR5X on a 384-bit bus, and 547.6 GB/s of bandwidth. The Radeon 780M is built for integration, with 768 shading units, 48 TMUs, 32 ROPs, 12 ray tracing cores, and a shared memory architecture that keeps power draw at 15 W. One is a performance monster; the other is an efficiency-focused component for systems where a discrete card is not an option.

The Verdict

The data is decisive: any user whose priority is raw graphics performance should choose the NVIDIA TITAN Xp. It wins 3 out of 3 recorded head-to-head tests, with deltas ranging from 158.8% to 394.2%. Its average benchmark score of 19177 places it just 0.1% ahead of the NVIDIA GeForce GTX 780 and 0.7% ahead of both the NVIDIA GeForce RTX 4050 Mobile and the AMD Radeon RX 6600. It sits at the 64th percentile of all GPUs in the database. For desktop workloads where power draw and physical space are not limiting factors, the TITAN Xp is the clear winner in every measured category.

The AMD Radeon 780M is the right choice only in a different context. Its average benchmark score of 17588 is only 0.3% behind the NVIDIA GeForce RTX 4060 in the nearest rival list, and it sits at the 61st percentile. It is an active, current product with a 2024 release date, while the TITAN Xp is end-of-life with a 2017 release date. The Radeon 780M draws 15 W, requires no power connectors, uses no slot width, and depends on the motherboard for display outputs. If the requirement is a low-power integrated GPU for a compact or mobile system, the Radeon 780M is the only viable option of the two, because the TITAN Xp cannot be integrated at all.

But the verdict must be stated plainly: for benchmark performance, the TITAN Xp wins every single recorded test. The Radeon 780M wins none. The data does not support any other conclusion.

Head-to-Head Benchmarks

The largest win for the NVIDIA TITAN Xp comes in 3DMark Steel Nomad DX12. The TITAN Xp scores 2372, and the Radeon 780M scores 480. That is a 394.2% delta, meaning the TITAN Xp delivers nearly five times the score of the Radeon 780M in this particular DirectX 12 workload. This is the kind of result that separates a discrete flagship from an integrated part: the TITAN Xp has 3840 shading units against 768, 240 TMUs against 48, 96 ROPs against 32, and 547.6 GB/s of dedicated memory bandwidth versus a system-dependent shared memory configuration.

The second largest win is in Geekbench OpenCL, where the TITAN Xp scores 72585 against 18602 for the Radeon 780M, a 290.2% delta. OpenCL compute workloads often scale with raw shader throughput and memory bandwidth, and the TITAN Xp's 12.15 TFLOPS of FP32 performance dwarfs the Radeon 780M's 8.909 TFLOPS. The TITAN Xp also has a significant memory advantage: 12 GB of GDDR5X on a 384-bit bus delivering 547.6 GB/s, whereas the Radeon 780M's memory performance is listed as System Dependent.

The smallest win, though still substantial, is in Geekbench Vulkan. The TITAN Xp scores 87180, and the Radeon 780M scores 33683, a 158.8% delta. Vulkan is a lower-overhead API, and the Radeon 780M's RDNA 3.0 architecture with 12 ray tracing cores helps it close some of the gap compared to the other tests. Still, the TITAN Xp nearly doubles the score. The TITAN Xp's pixel rate of 151.9 GPixel/s and texture rate of 379.7 GTexel/s are both far above the Radeon 780M's 92.80 GPixel/s and 139.2 GTexel/s, and those advantages show up across all three workloads.

The average benchmark scores tell a similar story. The TITAN Xp averages 19177 across its recorded tests, while the Radeon 780M averages 17588. That is a 1589-point gap, or roughly 9% overall. The TITAN Xp's nearest rivals include the GeForce GTX 780 at 19164, the Tesla K20m at 19089, the RTX 4050 Mobile at 19049, and the Radeon RX 6600 at 19036. The Radeon 780M's nearest rivals include the Radeon Pro 560 at 17551, the RTX 4060 at 17639, the Radeon HD 7790 at 17666, and the Radeon Pro 460 at 17509. The two products occupy different performance tiers entirely, with no overlap in their nearest rival groups.

Architecture Differences

The two GPUs come from different architectural eras and design philosophies. The NVIDIA TITAN Xp uses the GP102 chip on the Pascal architecture, manufactured on a 16 nm process at TSMC. It packs 11,800 million transistors into a 471 mm² die, for a transistor density of 25.1M per mm². The AMD Radeon 780M uses the Phoenix chip on the RDNA 3.0 architecture, also manufactured at TSMC but on a 4 nm process. It contains 25,390 million transistors in a 178 mm² die, for a transistor density of 142.6M per mm². The Radeon 780M has more than twice the transistor count in less than half the die area, a direct consequence of the newer process node.

Clock speeds differ substantially. The TITAN Xp runs at a 1405 MHz base clock and a 1582 MHz boost clock, with memory clocked at 1426 MHz, or 11.4 Gbps effective. The Radeon 780M has an 800 MHz base clock and a 2900 MHz boost clock, with system shared memory. The Radeon 780M's boost clock is nearly double the TITAN Xp's, but it has far fewer execution units.

The execution resources are heavily skewed toward the TITAN Xp. It has 3840 shading units, 240 TMUs, and 96 ROPs. The Radeon 780M has 768 shading units, 48 TMUs, and 32 ROPs. The TITAN Xp has 4 times the shading units, 5 times the TMUs, and 3 times the ROPs. The TITAN Xp also leads in fill rates: 151.9 GPixel/s pixel rate and 379.7 GTexel/s texture rate, versus 92.80 GPixel/s and 139.2 GTexel/s for the Radeon 780M.

Compute throughput is closer than the unit counts suggest. The TITAN Xp delivers 12.15 TFLOPS of FP32 performance, while the Radeon 780M delivers 8.909 TFLOPS. But FP16 performance is radically different. The Radeon 780M delivers 8.909 TFLOPS of FP16 at a 1:1 ratio, meaning it has full-rate FP16. The TITAN Xp delivers only 189.8 GFLOPS of FP16 at a 1:64 ratio, meaning its FP16 throughput is severely limited. This is a meaningful architectural difference: the Radeon 780M is designed for modern workloads that use FP16, while the TITAN Xp is optimized for FP32.

The Radeon 780M also includes 12 ray tracing cores, a feature the TITAN Xp lacks entirely. The TITAN Xp predates the ray tracing era; it belongs to the GeForce 10 generation, with the GeForce 900 as its predecessor and the GeForce 20 as its successor. The Radeon 780M is part of the Navi III IGP generation, with the Navi II IGP as its predecessor and Navi III IGP as its successor.

API support differs in DirectX only. Both support OpenGL 4.6 and Vulkan 1.4. The TITAN Xp supports DirectX 12 (12_1), while the Radeon 780M supports DirectX 12 Ultimate (12_2). The Radeon 780M's newer API level reflects its 2024 release date, versus the TITAN Xp's 2017 release. The TITAN Xp uses PCIe 3.0 x16, while the Radeon 780M uses PCIe 4.0 x8.

Form factor and power are entirely different. The TITAN Xp is a dual-slot card measuring 267 mm in length, 112 mm in height, and 40 mm in width, with a 250 W TDP, one 6-pin and one 8-pin power connector, and a suggested 600 W PSU. The Radeon 780M is an IGP with no slot width, no power connectors, no dimensions, and a 15 W TDP. The TITAN Xp has 1x HDMI 2.0 and 3x DisplayPort 1.4a outputs; the Radeon 780M's display outputs are motherboard dependent.

Finally, the TITAN Xp is end-of-life, with a launch MSRP of 1,199 USD. The Radeon 780M is active and has no launch MSRP listed. The TITAN Xp is a finished product from a previous generation; the Radeon 780M is a current integrated solution. The data shows two products that share almost nothing except the GPU label.
