AMD Radeon 880M vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

AMD Radeon 880M and NVIDIA GeForce RTX 5070 Ti Mobile occupy the same 79th percentile among all GPUs, yet their benchmark profiles could hardly be more different. The RTX 5070 Ti Mobile wins both head-to-head tests decisively, but the 880M’s average score of 35,646 stays within 0.6% of the NVIDIA part’s 35,435, creating an unusual situation where two products with near-identical aggregate performance diverge sharply in individual workloads.

Head-to-Head Benchmarks

The GeForce RTX 5070 Ti Mobile dominates both shared benchmark tests, starting with Geekbench OpenCL where it scores 143,870 against the Radeon 880M’s 31,285. That represents a 78.3% advantage for NVIDIA, the largest gap in any metric between these two parts. The Vulkan result narrows slightly but remains lopsided: the RTX 5070 Ti Mobile posts 139,213 versus 40,006 for the 880M, a 71.3% margin. In raw compute throughput, these are not close contests — the NVIDIA part delivers roughly 3.5 to 4.6 times the performance depending on the API.

Yet the aggregate picture tells a different story. The 880M’s average benchmark score of 35,646 edges out the RTX 5070 Ti Mobile’s 35,435 by 0.6%, meaning the AMD part compensates for its Geekbench losses with strength elsewhere in the benchmark suite. The RTX 5070 Ti Mobile’s Passmark results reveal why: its DirectX 10 score of 151, DirectX 11 score of 237, DirectX 12 score of 102, and DirectX 9 score of 259 are all extremely low, while its Passmark G3D score reaches 24,004 and its GPU compute score hits 10,101. The 880M’s two Geekbench results alone average to roughly 35,646, suggesting the AMD part has no weak spots in its limited test set, whereas the NVIDIA part’s average is dragged down by the Passmark legacy DirectX tests.

Looking at nearest rivals confirms the odd positioning. The RTX 5070 Ti Mobile sits 0.3% above the AMD Radeon RX 6750 XT (35,327) and 0.5% above the AMD Radeon RX 5600M (35,264), while trailing the NVIDIA GeForce RTX 3080 by 1%. The 880M, meanwhile, is 0.4% behind the RTX 3080 and 0.6% behind the RTX 5070 Ti Mobile in their respective listings — but the head-to-head delta shows the 880M at 0.6% ahead of the RTX 5070 Ti Mobile when comparing their average scores directly. The two parts are effectively tied in aggregate, making their individual test disparities all the more striking.

Where Each One Wins

The RTX 5070 Ti Mobile wins exclusively in modern compute-heavy workloads. Its Geekbench OpenCL score of 143,870 and Vulkan score of 139,213 represent the kind of sustained throughput expected from a discrete-class mobile GPU with 5,888 shading units. Any workload that scales well with shading unit count, texture mapping, or ray tracing will favor the NVIDIA part by margins exceeding 70%. The data shows no scenario where the 880M wins a head-to-head test — it records zero wins across the two shared benchmarks.

The 880M’s advantage is entirely relative. Its aggregate score of 35,646 comes from just two tests, both Geekbench, and both losses. But because the RTX 5070 Ti Mobile’s Passmark legacy DirectX scores are so low — 151 in DX10, 237 in DX11, 102 in DX12, 259 in DX9 — the NVIDIA part’s average falls to 35,435. The 880M effectively “wins” by not having those weak legacy results, even though it never outperforms the RTX 5070 Ti Mobile in any shared workload. For applications that rely on older DirectX paths, the 880M’s absence of embarrassingly low scores makes it the more consistent performer, while the RTX 5070 Ti Mobile’s enormous lead in OpenCL and Vulkan makes it the clear choice for compute-oriented tasks.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. AMD’s 880M uses the Strix Point chip built on RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. NVIDIA’s RTX 5070 Ti Mobile uses the GB205 chip on Blackwell 2.0 architecture, also from TSMC but on a 5 nm node. The process difference translates into transistor density: AMD packs 34,000 million transistors into 233 mm² for a density of 145.9 million per mm², while NVIDIA fits 31,100 million transistors into 263 mm² at 118.3 million per mm². The 880M is denser despite being the integrated part.

Core counts diverge sharply. The 880M fields 768 shading units, 48 texture mapping units, 16 ROPs, and 12 ray tracing cores. The RTX 5070 Ti Mobile counters with 5,888 shading units, 184 TMUs, 80 ROPs, 46 RT cores, and 184 tensor cores — the latter having no direct equivalent in the AMD part, which lists no tensor cores. The NVIDIA GPU’s FP32 throughput of 17.04 TFLOPS compares to the 880M’s 4.454 TFLOPS, a 3.8x difference. FP16 tells a similar story: NVIDIA matches its FP32 at 17.04 TFLOPS (1:1 ratio), while AMD achieves 8.909 TFLOPS at a 2:1 ratio.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The RTX 5070 Ti Mobile’s 46 RT cores versus the 880M’s 12 RT cores suggests NVIDIA has invested far more in ray tracing hardware, consistent with its Blackwell 2.0 architecture targeting higher-end mobile workloads.

Specification Differences

The most consequential differences appear in memory and interface specifications. The RTX 5070 Ti Mobile comes with 12 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The 880M uses system shared memory — size, type, bus width, and bandwidth are all listed as “System Shared” or “System Dependent,” meaning its memory performance depends entirely on the host system’s configuration. This is the single largest practical distinction: the NVIDIA part has dedicated, high-bandwidth VRAM while the AMD part borrows from system memory.

Clock speeds also differ substantially. The RTX 5070 Ti Mobile runs at a base of 847 MHz and boosts to 1,447 MHz, with memory clocked at 1,750 MHz (28 Gbps effective). The 880M has a lower base of 400 MHz but a much higher boost of 2,900 MHz, reflecting its integrated design’s ability to spike under load. Pixel rate favors NVIDIA at 115.8 GPixel/s versus 46.40 GPixel/s, and texture rate follows suit at 266.2 GTexel/s versus 139.2 GTexel/s.

Power and interface specs diverge as well. The 880M carries a 15 W TDP while the RTX 5070 Ti Mobile draws 60 W — a 4x difference that explains why the NVIDIA part can sustain far higher clocks and throughput. Both use PCIe, but the 880M runs PCIe 4.0 x8 while the RTX 5070 Ti Mobile uses PCIe 5.0 x16. Neither has power connectors, and both are classified as IGP slot width with “Portable Device Dependent” display outputs. The RTX 5070 Ti Mobile lists no release date, while the 880M shipped on 2024-07-14.

The Verdict

The data supports a clear split decision. For users who prioritize compute performance in modern APIs, the NVIDIA GeForce RTX 5070 Ti Mobile is the only choice: it leads by 78.3% in OpenCL and 71.3% in Vulkan, offers 3.8x the FP32 throughput (17.04 TFLOPS vs 4.454 TFLOPS), and brings 46 RT cores and 184 tensor cores that the 880M cannot match. Its 12 GB GDDR7 with 672.0 GB/s bandwidth provides dedicated memory that no integrated solution can replicate.

The AMD Radeon 880M’s case rests on efficiency and consistency. At 15 W versus 60 W, it draws one-quarter the power while achieving a comparable average score of 35,646 versus 35,435. Its 4 nm process and higher transistor density (145.9M/mm² vs 118.3M/mm²) suggest a more modern design, and its boost clock of 2,900 MHz far exceeds the NVIDIA part’s 1,447 MHz. For systems where the Passmark legacy DirectX scores matter — the RTX 5070 Ti Mobile’s DX9 through DX12 results all sit below 260 — the 880M avoids the NVIDIA part’s pronounced weaknesses.

The verdict hinges on workload. The RTX 5070 Ti Mobile targets users who need maximum throughput in OpenCL and Vulkan, accept a 60 W power draw, and can tolerate poor legacy DirectX performance. The 880M suits users who want competitive average scores at 15 W, value process efficiency, and prioritize consistency across the few benchmarks it runs. Neither part dominates the other in aggregate — the 0.6% average score difference is negligible — but their character could not be more distinct.
