Architecture Differences

The AMD Ryzen Z2 A GPU and the Intel Arc 140V Mobile represent two divergent design philosophies for integrated graphics. The AMD part is built on the RDNA 2.0 architecture using TSMC's 7 nm process, with the Van Gogh chip. The Intel part employs the Xe2-LPG architecture on TSMC's 3 nm process, using the Lunar Lake chip. The process node difference is substantial: 7 nm versus 3 nm, which directly informs the transistor density and power characteristics.

The AMD GPU contains 2,400 million transistors on a 163 mm² die, yielding a transistor density of 14.7M per mm². The Intel GPU reports an unknown transistor count on a 172 mm² die. This means the Intel die is physically larger at 172 mm² versus 163 mm², though the density comparison cannot be completed because Intel's transistor count is not recorded.

The shading resources differ significantly. The AMD Ryzen Z2 A GPU has 512 shading units, 32 TMUs, and 16 ROPs. The Intel Arc 140V Mobile doubles these counts in most categories: 1024 shading units, 64 TMUs, and 32 ROPs. Both GPUs have 8 ray tracing cores. Neither GPU has tensor cores listed.

Memory architecture is a fundamental differentiator. The AMD GPU uses 16 GB of dedicated LPDDR5 memory on a 128-bit bus, delivering 102.4 GB/s of bandwidth. The Intel GPU uses System Shared memory with System Dependent bandwidth, meaning it relies on the host system's memory configuration. This gives AMD a fixed, dedicated memory pool, while Intel's memory performance scales with the system.

Clock behavior also differs. The AMD GPU has a base clock of 1000 MHz and a boost clock of 1600 MHz. The Intel GPU has a much lower base clock of 300 MHz but a higher boost clock of 1950 MHz. The memory clock for AMD is 800 MHz, 6.4 Gbps effective, while Intel's memory clock is System Shared.

The power envelope is another clear split. The AMD Ryzen Z2 A GPU is rated at 15 W TDP, while the Intel Arc 140V Mobile is rated at 37 W TDP. This is a 22 W difference, which has direct implications for thermal design and battery life in mobile devices. The Intel part is an IGP with a slot width of IGP and a bus interface of IGP, while the AMD part does not list a slot width or bus interface.

Display outputs also differ. The AMD GPU lists 1x USB Type-C as its display output. The Intel GPU lists Portable Device Dependent, indicating the output configuration varies by the host device.

Where Each One Wins

The Intel Arc 140V Mobile wins in raw compute throughput across every measured metric. Its FP32 performance of 3.994 TFLOPS is 2.356 TFLOPS higher than the AMD's 1.638 TFLOPS, a lead of roughly 144%. Its FP16 performance of 7.987 TFLOPS is 4.710 TFLOPS higher than the AMD's 3.277 TFLOPS. Pixel rate favors Intel at 62.40 GPixel/s versus 25.60 GPixel/s, and texture rate favors Intel at 124.8 GTexel/s versus 51.20 GTexel/s. These figures indicate Intel has a decisive advantage in fill-rate-limited workloads and general compute.

The AMD Ryzen Z2 A GPU wins in power efficiency. At 15 W TDP, it delivers 1.638 TFLOPS FP32, which is 0.109 TFLOPS per watt. The Intel Arc 140V Mobile at 37 W TDP delivers 3.994 TFLOPS FP32, which is 0.108 TFLOPS per watt. The efficiency figures are nearly identical, but AMD achieves this at a much lower absolute power draw. For systems constrained by battery capacity or thermal limits, the AMD part offers a lighter power burden.

AMD also wins on memory independence. The 16 GB dedicated LPDDR5 pool with 102.4 GB/s bandwidth is a fixed resource that does not compete with the CPU for system memory. The Intel GPU's System Shared memory means bandwidth is System Dependent, which can vary based on the host system's memory configuration. The AMD design provides predictable memory performance.

The Intel Arc 140V Mobile wins on clock boost headroom. Its boost clock of 1950 MHz is 350 MHz higher than the AMD's 1600 MHz boost. The Intel part also has a much lower base clock of 300 MHz, indicating a wider dynamic range between idle and peak operation.

Head-to-Head Benchmarks

The recorded benchmark data shows no direct head-to-head benchmark entries, zero wins for either GPU, and no nearest rival comparisons. However, the specification data provides a clear quantitative comparison across all compute metrics.

The largest win for the Intel Arc 140V Mobile is in FP16 compute. Intel delivers 7.987 TFLOPS, which is 4.710 TFLOPS higher than the AMD Ryzen Z2 A GPU's 3.277 TFLOPS. This is more than double the AMD figure, indicating Intel has a substantial advantage in workloads that can use half-precision arithmetic.

In FP32 compute, Intel delivers 3.994 TFLOPS versus AMD's 1.638 TFLOPS, a difference of 2.356 TFLOPS. This translates to Intel being approximately 2.44 times faster in single-precision compute. This is the metric most relevant to general gaming and compute workloads.

The texture rate shows Intel at 124.8 GTexel/s versus AMD at 51.20 GTexel/s. The difference is 73.6 GTexel/s. Texture rate is critical for scenes with heavy texture sampling, and Intel's advantage here is substantial.

The pixel rate shows Intel at 62.40 GPixel/s versus AMD at 25.60 GPixel/s. The difference is 36.8 GPixel/s. Pixel rate affects resolution and fill-rate-bound scenarios, where Intel again holds a decisive lead.

The only metric where AMD does not trail is power consumption. At 15 W TDP, AMD draws 22 W less than Intel's 37 W TDP. The efficiency per watt is nearly identical at 0.109 TFLOPS per watt for AMD and 0.108 TFLOPS per watt for Intel, but AMD achieves this at a lower absolute power level.

The clock speeds show a different pattern. AMD has a higher base clock at 1000 MHz versus Intel's 300 MHz, but Intel has a higher boost clock at 1950 MHz versus AMD's 1600 MHz. The dynamic range is much wider on Intel, with a 1650 MHz span from base to boost, compared to AMD's 600 MHz span.

The memory configuration gives AMD a fixed bandwidth of 102.4 GB/s, while Intel's bandwidth is System Dependent. In systems with high-bandwidth shared memory, Intel could approach or exceed AMD's fixed bandwidth, but the recorded data does not specify a value.

The Verdict

The data indicates that the Intel Arc 140V Mobile is the higher-performance GPU in almost every compute metric. Its FP32 performance of 3.994 TFLOPS is more than double the AMD Ryzen Z2 A GPU's 1.638 TFLOPS. Its FP16 performance of 7.987 TFLOPS is more than double AMD's 3.277 TFLOPS. Its pixel rate of 62.40 GPixel/s and texture rate of 124.8 GTexel/s both exceed AMD's 25.60 GPixel/s and 51.20 GTexel/s by wide margins. The Intel GPU also has double the shading units, TMUs, and ROPs.

The AMD Ryzen Z2 A GPU is the lower-power option. Its 15 W TDP is 22 W lower than Intel's 37 W TDP. For devices where power draw and thermal output are primary constraints, the AMD part presents a lighter load. Its 16 GB dedicated memory pool with 102.4 GB/s bandwidth provides fixed, predictable memory performance that does not depend on the host system.

The architecture comparison favors Intel on process technology. The 3 nm TSMC process versus AMD's 7 nm TSMC process gives Intel a manufacturing advantage. The Intel die is also slightly larger at 172 mm² versus 163 mm², despite the denser process.

The release timeline shows Intel launched first, with a release date of 2024-09-23, while AMD's release date is 2024-12-31. Both are Active in production.

For users prioritizing raw performance, the Intel Arc 140V Mobile is the clear choice based on the recorded specifications. For users prioritizing lower power draw with dedicated memory, the AMD Ryzen Z2 A GPU offers a viable alternative, though with substantially lower compute throughput. The choice depends on whether the system values performance or power economy, and the data supports Intel for the former and AMD for the latter.
