AMD Radeon 880M vs AMD Ryzen Z2 GPU Comparison

FAQ

Q: What are the architecture differences between the AMD Radeon 880M and the AMD Ryzen Z2 GPU?

A: The Radeon 880M uses the RDNA 3.5 architecture on the Strix Point chip, while the Ryzen Z2 GPU uses RDNA 3.0 on the Hawk Point chip. Both are built on TSMC's 4 nm process, but the 880M has 34,000 million transistors on a 233 mm² die, whereas the Ryzen Z2 GPU has 25,390 million transistors on a 178 mm² die.

Q: How do the clock speeds compare between the two GPUs?

A: The Radeon 880M has a base clock of 400 MHz and a boost clock of 2900 MHz. The Ryzen Z2 GPU has a base clock of 800 MHz and a boost clock of 2700 MHz. The Ryzen Z2 GPU starts at a higher base frequency, but the 880M reaches a higher boost frequency.

Q: Which GPU has higher raw compute throughput?

A: The Ryzen Z2 GPU delivers 8.294 TFLOPS FP32, nearly double the 4.454 TFLOPS of the Radeon 880M. Both GPUs have 768 shading units and 48 TMUs, but the Ryzen Z2 GPU has 32 ROPs versus 16 on the 880M.

Q: What memory configurations do the two GPUs use?

A: The Radeon 880M uses system-shared memory with bandwidth described as system dependent. The Ryzen Z2 GPU has 16 GB of LPDDR5X memory on a 128-bit bus with 119.9 GB/s bandwidth.

Q: What is the thermal design power difference?

A: The Radeon 880M has a 15 W TDP, while the Ryzen Z2 GPU has a 28 W TDP. The Ryzen Z2 GPU consumes 13 W more, which aligns with its higher FP32 throughput and dedicated memory.

Q: How does the Radeon 880M rank among all GPUs?

A: The Radeon 880M sits at the 43rd percentile of all GPUs in the database with an average benchmark score of 8436. Its nearest rivals are the NVIDIA GeForce GTX 675MX (8427, 0.1% ahead), AMD Radeon HD 8870M (8462, 0.3% behind), and NVIDIA GeForce MX330 (8458, 0.3% behind).

Architecture Differences

The Radeon 880M is built on RDNA 3.5, the newer instruction set, while the Ryzen Z2 GPU uses RDNA 3.0. Both are fabricated by TSMC on a 4 nm process, but the chip designs differ substantially. The 880M uses the Strix Point chip with 34,000 million transistors spread across 233 mm², giving a transistor density of 145.9 million per mm². The Ryzen Z2 GPU uses Hawk Point with 25,390 million transistors on 178 mm², a density of 142.6 million per mm².

Both GPUs share the same counting of 768 shading units, 48 texture mapping units, and 12 ray tracing cores. The ROP count differs, with the 880M at 16 and the Ryzen Z2 GPU at 32. That doubling of ROPs directly explains the pixel rate gap: the 880M outputs 46.40 GPixel/s, while the Ryzen Z2 GPU outputs 86.40 GPixel/s.

The memory architecture is the other major divergence. The 880M relies on system-shared memory with no dedicated video memory, a bus width, or fixed bandwidth. The Ryzen Z2 GPU has 16 GB of LPDDR5X on a 128-bit interface delivering 119.9 GB/s. The Ryzen Z2 GPU also runs its memory at 937 MHz with 7.5 Gbps effective speed.

Clock behavior differs as well. The 880M idles at 400 MHz but boosts to 2900 MHz. The Ryzen Z2 GPU starts higher at 800 MHz base but caps at 2700 MHz boost. The higher boost clock on the 880M does not overcome the Ryzen Z2 GPU's compute advantage: 4.454 TFLOPS FP32 on the 880M versus 8.294 TFLOPS on the Ryzen Z2 GPU. FP16 throughput matches FP32 on both at a 1:1 ratio.

The Radeon 880M is classified as an IGP with PCIe 4.0 x8 interface and no power connectors. The Ryzen Z2 GPU is listed as a console GPU with a single USB Type-C display output. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The recorded data separates these two GPUs clearly by role. The Ryzen Z2 GPU doubles the FP32 throughput, doubles the ROP count, uses 16 GB of dedicated LPDDR5X memory, and delivers nearly twice the pixel rate of the Radeon 880M. It occupies the 50th percentile of all GPUs, compared to the 880M's 43rd percentile.

The Radeon 880M is a low-power integrated part at 15 W with system-shared memory. Its strength is efficiency and compactness, as an IGP with no power connectors. The Ryzen Z2 GPU at 28 W is a higher-power part with its own memory pool and a console GPU designation.

For workloads that depend on raw shader throughput, memory bandwidth, or pixel fill, the Ryzen Z2 GPU is the stronger choice. For an integrated solution that draws less power and uses shared system memory, the Radeon 880M fits that slot. The data does not show the Ryzen Z2 GPU losing in any measured compute category.

Head-to-Head Benchmarks

The database has no direct head-to-head benchmark entries between the Radeon 880M and the Ryzen Z2 GPU. The Ryzen Z2 GPU has an empty benchmark list with an average score of 0 and no nearest rivals recorded. The Radeon 880M, by contrast, has ten logged benchmark scores.

The 880M's 3DMark Steel Nomad DX12 score is 535. In Geekbench, it scores 31285 in OpenCL and 40006 in Vulkan. PassMark results show 7615 in G3D, 969 in G2D, 3719 in GPU compute, 97 in DirectX 9, 73 in DirectX 11, 32 in DirectX 12, and 31 in DirectX 10.

Without direct comparison data, the specification sheet carries the analysis. The Ryzen Z2 GPU's 8.294 TFLOPS FP32 is 86.2% higher than the 880M's 4.454 TFLOPS. Its pixel rate of 86.40 GPixel/s is nearly double the 46.40 GPixel/s of the 880M. The texture rate is the one metric where the 880M leads: 139.2 GTexel/s versus 129.6 GTexel/s, a 7.4% advantage.

The Ryzen Z2 GPU also holds a memory advantage that cannot be quantified against the 880M, since the 880M's bandwidth is system dependent. The Ryzen Z2 GPU's fixed 119.9 GB/s over a 128-bit LPDDR5X bus provides a deterministic baseline, whereas the 880M's performance scales with the host system's memory configuration.

The percentile ranking favors the Ryzen Z2 GPU at 50th percentile versus the 880M at 43rd. The 880M's nearest rivals in the database are all discrete mobile GPUs from the NVIDIA GTX 600 series, NVIDIA MX series, and AMD Radeon HD/R9 mobile lines, with deltas of 0.1% to 1.3%. That places the 880M in the same performance band as those older discrete parts.

Where Each One Wins

The Ryzen Z2 GPU wins in raw compute throughput, pixel fill, memory capacity, and memory bandwidth. Its 8.294 TFLOPS FP32 makes it the clear choice for shader-heavy rendering, and its 32 ROPs with 86.40 GPixel/s handle fill-rate-bound scenes better. The dedicated 16 GB LPDDR5X at 119.9 GB/s removes reliance on system memory, a decisive factor for consistent frame pacing in gaming workloads.

The Radeon 880M wins in texture throughput, posting 139.2 GTexel/s versus 129.6 GTexel/s on the Ryzen Z2 GPU. It also draws less power at 15 W versus 28 W, making it suitable for thinner portable devices. The 880M's higher boost clock of 2900 MHz versus 2700 MHz helps in bursty, lightly threaded workloads, though the Ryzen Z2 GPU's higher base clock of 800 MHz keeps it responsive under sustained load.

The 880M is the only one of the two with a defined bus interface (PCIe 4.0 x8) and an IGP slot width, so it fits standard mobile motherboard integration. The Ryzen Z2 GPU is designated as a console GPU with a single USB Type-C display output, indicating a different deployment target.

For a portable device where power draw and system-shared memory are acceptable, the Radeon 880M provides texture rate leadership and lower TDP. For a console-style platform with fixed memory and higher compute demands, the Ryzen Z2 GPU is the stronger part. Each GPU wins in the category its design targets: the 880M for efficient integrated graphics, the Ryzen Z2 GPU for dedicated console-class performance.
