Architecture Differences
The AMD Radeon 880M is built on TSMC's 4 nm process using the RDNA 3.5 architecture, part of the Navi III IGP (Strix Point Mobile) generation with the Strix Point chip. The NVIDIA GRID K2 uses the older Kepler architecture on TSMC's 28 nm process with the GK104 chip, belonging to the GRID (K2) generation. The process node difference is stark: 4 nm versus 28 nm. Transistor density tells the story — the 880M achieves 145.9M transistors per mm² across a 233 mm² die, while the GRID K2 manages just 12.0M per mm² on a larger 294 mm² die. The 880M's total transistor count of 34,000 million dwarfs the GRID K2's 3,540 million.
Feature-wise, the 880M includes 12 RT cores for ray tracing, while the GRID K2 has none. The 880M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the GRID K2 tops out at DirectX 12 (11_0) and Vulkan 1.2.175. Both support OpenGL 4.6. The 880M uses a PCIe 4.0 x8 interface, while the GRID K2 uses PCIe 3.0 x16. The GRID K2 has no display outputs at all — it is a compute-oriented card — while the 880M's outputs are "Portable Device Dependent," reflecting its IGP nature. The 880M's predecessor is the Navi II IGP; the GRID K2 has no listed predecessor or successor.
Where Each One Wins
The AMD Radeon 880M wins decisively in the only shared benchmark, Geekbench OpenCL, by 195.1%. The data suggests the 880M is the stronger compute performer for general-purpose workloads. Its 4.454 TFLOPS FP32 output versus the GRID K2's 2.289 TFLOPS reinforces this. The 880M also has higher pixel rate (46.40 GPixel/s vs 23.84 GPixel/s) and texture rate (139.2 GTexel/s vs 95.36 GTexel/s). For graphics rendering, the 880M's RDNA 3.5 architecture with DirectX 12 Ultimate support positions it for modern gaming workloads, including ray tracing via its 12 RT cores.
The NVIDIA GRID K2, by contrast, has no benchmark wins in this dataset. Its strengths lie elsewhere: it has dedicated 4 GB GDDR5 memory with 160.0 GB/s bandwidth, which is fixed and not dependent on system memory. It also has more shading units (1536 vs 768), more TMUs (128 vs 48), and more ROPs (32 vs 16). The GRID K2's dual-slot design with 1x 6-pin and 1x 8-pin power connectors suggests it was built for server or workstation environments where discrete, persistent memory matters. The 880M's system-shared memory means its performance scales with system RAM speed and capacity, which is a variable the GRID K2 does not face.
Specification Differences
The two GPUs differ on nearly every specification. The AMD Radeon 880M has a base clock of 400 MHz and boost clock of 2900 MHz, while the GRID K2 lists no base or boost clocks — only a memory clock of 1250 MHz (5 Gbps effective). Memory configuration differs fundamentally: the 880M uses system-shared memory of unspecified size and type, while the GRID K2 has 4 GB GDDR5 on a 256-bit bus. Bandwidth is "System Dependent" for the 880M versus a fixed 160.0 GB/s for the GRID K2.
Shading units: 768 on the 880M versus 1536 on the GRID K2. TMUs: 48 vs 128. ROPs: 16 vs 32. The 880M has 12 RT cores; the GRID K2 has none. FP32 compute: 4.454 TFLOPS vs 2.289 TFLOPS. FP16: the 880M has 4.454 TFLOPS (1:1), while the GRID K2 has no listed FP16 performance. Pixel rate: 46.40 GPixel/s vs 23.84 GPixel/s. Texture rate: 139.2 GTexel/s vs 95.36 GTexel/s.
TDP: 15 W for the 880M, 225 W for the GRID K2. The 880M is an IGP with no slot width and no power connectors; the GRID K2 is dual-slot, 267 mm (10.5 inches) long, requiring 1x 6-pin + 1x 8-pin power and a 550 W suggested PSU. The GRID K2 has a launch MSRP of 5,199 USD. The 880M has no launch MSRP listed. The 880M's bus interface is PCIe 4.0 x8; the GRID K2's is PCIe 3.0 x16.
Head-to-Head Benchmarks
The sole head-to-head benchmark is Geekbench OpenCL, where the AMD Radeon 880M scores 31285 against the NVIDIA GRID K2's 10602. That is a 195.1% delta — the 880M more than triples the GRID K2's score. To put that in perspective, the 880M's nearest rivals in the overall database are the NVIDIA GeForce GTX 675MX (avg score 8427, delta 0.1%), the NVIDIA GeForce MX330 (8458, delta -0.3%), and the AMD Radeon HD 8870M (8462, delta -0.3%). The GRID K2's nearest rivals are the NVIDIA GeForce GTX 650 Ti Boost (8067, delta 0.2%), the NVIDIA GeForce 945M (8099, delta -0.2%), and the NVIDIA GeForce GTX 650 Ti (8053, delta 0.3%). Both GPUs sit within 1.3% of their nearest competitors, indicating they are closely matched to their respective peer groups.
The 880M's OpenCL score of 31285 is roughly 3.7 times the GRID K2's OpenCL score of 10602. This aligns with the FP32 compute gap: 4.454 TFLOPS versus 2.289 TFLOPS. The 880M also has a higher Geekbench Vulkan score of 40006, though no Vulkan score exists for the GRID K2. The GRID K2 only has a Geekbench Metal score of 5557, which the 880M does not have. The 880M's Passmark scores include G3D at 7615, G2D at 969, and GPU Compute at 3719. The GRID K2 has no Passmark scores listed. In the wins tally, the 880M wins 1, the GRID K2 wins 0.
The Verdict
The data points to a clear overall winner: the AMD Radeon 880M. It wins the only direct benchmark by a 195.1% margin, has nearly double the FP32 compute throughput (4.454 vs 2.289 TFLOPS), and does so at 15 W versus 225 W TDP. Its 4 nm RDNA 3.5 architecture with 12 RT cores and DirectX 12 Ultimate support makes it the modern choice for any workload involving ray tracing or the latest graphics APIs. The 880M's 43rd percentile ranking versus the GRID K2's 42nd percentile is close, but the average benchmark score of 8436 versus 8080 favors AMD.
Who should pick the AMD Radeon 880M? Anyone needing an integrated GPU with strong compute performance in a low-power, portable form factor. Its system-shared memory means it is best suited to laptops or compact devices where dedicated VRAM is not a requirement. The 880M is Active production status, so it is currently available. The 880M's nearest rival, the GTX 675MX, is just 0.1% behind in average score, so the 880M is competitive within its peer group.
Who should pick the NVIDIA GRID K2? The case is narrow but real. The GRID K2 offers 4 GB of dedicated GDDR5 memory with fixed 160.0 GB/s bandwidth, which the 880M cannot match with its system-dependent memory. It also has double the shading units (1536 vs 768) and more TMUs and ROPs, which could benefit specific compute patterns that favor raw parallelism over memory flexibility. However, the GRID K2 is End-of-life, has no display outputs, and requires a 550 W PSU. Its 5,199 USD launch MSRP reflects its enterprise positioning. For a server environment where dedicated memory is non-negotiable and the 28 nm Kepler architecture is acceptable, the GRID K2 remains an option — but the benchmark data shows it is decisively slower in compute. The 880M is the better performer by the numbers, and the GRID K2's advantages are confined to memory architecture and raw unit counts that do not translate into benchmark wins.
