AMD Ryzen Z2 A GPU vs Intel Arc 140T Mobile Comparison

Where Each One Wins

The recorded data separates these two mobile graphics solutions primarily by design intent and performance envelope. The AMD Ryzen Z2 A GPU is a 15 W part built on the Van Gogh chip with RDNA 2.0 architecture, while the Intel Arc 140T Mobile is a 35 W integrated GPU based on Arrow Lake-H with Xe-LPG+ architecture.

In raw compute throughput, the Intel Arc 140T Mobile holds a decisive advantage. Its FP32 output is 4.813 TFLOPS versus 1.638 TFLOPS for the AMD part, which translates to roughly three times the single-precision compute capacity. The FP16 numbers follow the same pattern: 9.626 TFLOPS for Intel against 3.277 TFLOPS for AMD. These figures indicate that the Intel solution delivers substantially higher shader throughput for workloads that scale with raw ALU performance.

The pixel and texture processing rates tell a similar story. Intel's Arc 140T Mobile reaches 75.20 GPixel/s and 150.4 GTexel/s, while the AMD Ryzen Z2 A GPU manages 25.60 GPixel/s and 51.20 GTexel/s. The Intel part is nearly three times faster in both rasterization and texture fetch operations, which suggests a significant edge in fill-rate-bound scenarios such as high-resolution rendering or heavy post-processing effects.

However, the AMD Ryzen Z2 A GPU wins in the context of power efficiency and form factor integration. Its 15 W TDP is less than half of Intel's 35 W TDP, and it comes with dedicated 16 GB of LPDDR5 memory on a 128-bit bus delivering 102.4 GB/s of bandwidth. The Intel part uses system-shared memory with bandwidth that is system dependent, meaning its effective memory performance is tied to the host platform's configuration. For handheld consoles or compact portable devices where power draw and memory allocation are tightly constrained, the AMD solution's fixed memory pool and lower thermal budget provide a structural advantage.

The AMD GPU also has a faster base clock at 1000 MHz versus 300 MHz for Intel, though the Intel part boosts much higher at 2350 MHz versus 1600 MHz. The base clock gap suggests AMD maintains a more consistent floor performance, while Intel's higher boost ceiling allows it to surge when thermal headroom permits. The AMD part's memory clock is specified at 800 MHz with 6.4 Gbps effective, another sign of its self-contained design.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Ryzen Z2 A GPU uses RDNA 2.0, a mature console-oriented architecture built on TSMC's 7 nm process. The chip integrates 2,400 million transistors on a 163 mm² die, yielding a transistor density of 14.7 million transistors per square millimeter. This is a dedicated, standalone GPU solution with its own VRAM, listed under the Console GPU (AMD) generation.

The Intel Arc 140T Mobile uses Xe-LPG+, a newer architecture derived from Intel's Arc Graphics-M family for Arrow Lake processors. It is fabricated on TSMC's 5 nm node, a more advanced process, though the database does not record its transistor count or die size. The Intel part is an integrated graphics processor (IGP) with a bus interface of IGP, meaning it shares the processor package and relies on system memory rather than dedicated VRAM.

Shader resource counts differ substantially. The AMD GPU has 512 shading units, 32 texture mapping units, and 16 raster operation units. The Intel GPU doubles those numbers: 1024 shading units, 64 TMUs, and 32 ROPs. This explains the proportional differences in texture rate and pixel rate observed above. Both parts have 8 ray tracing cores, but the architectural implementation differs given the distinct GPU generations.

Clock behavior also diverges. AMD runs a 1000 MHz base and 1600 MHz boost, a narrow range that suggests a power-limited design optimized for sustained operation. Intel runs a 300 MHz base and 2350 MHz boost, a wide spread that indicates aggressive power management, ramping up when thermals and power budgets allow, and dropping low during idle or light loads.

Memory architecture is the most fundamental split. AMD uses 16 GB of LPDDR5 on a 128-bit bus with a fixed 102.4 GB/s bandwidth. Intel uses system-shared memory of any size, type, or bus width determined by the host laptop, with bandwidth listed as system dependent. The AMD approach guarantees predictable memory performance and capacity for gaming, while the Intel approach offers flexibility but ties graphics performance to the quality and configuration of the host system's RAM.

API support is identical on paper: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The display outputs differ, with AMD offering a single USB Type-C port and Intel's being portable device dependent, reflecting its role as an integrated solution inside a laptop rather than a standalone chip.

The Verdict

The data points to a clear performance hierarchy. The Intel Arc 140T Mobile delivers roughly three times the FP32 compute, triple the pixel rate, and triple the texture rate compared to the AMD Ryzen Z2 A GPU. For any application that stresses raw graphics throughput, modern game rendering, or compute-heavy shader workloads, the Intel part is the stronger choice by a wide margin.

The AMD Ryzen Z2 A GPU, however, occupies a distinct niche. Its 15 W power envelope, dedicated 16 GB memory pool, and compact self-contained design make it suitable for handheld or ultra-portable devices where the Intel part's 35 W TDP and system-shared memory dependency would be less practical. The AMD solution offers a fixed, predictable memory configuration that does not compete with the CPU for bandwidth, which can be advantageous in tightly integrated console-like designs.

Neither part has recorded benchmark scores in the database, and both sit at the 50th percentile among all GPUs. Without measured performance data, the architectural specifications are the primary basis for comparison. The Intel Arc 140T Mobile is positioned for higher performance in conventional laptops with sufficient cooling and memory bandwidth. The AMD Ryzen Z2 A GPU is positioned for low-power, dedicated gaming handhelds where efficiency and memory determinism matter more than peak throughput.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results for these two GPUs, so the comparison rests entirely on the specification-derived throughput figures.

The largest win for the Intel Arc 140T Mobile is in pixel fill rate. It achieves 75.20 GPixel/s compared to 25.60 GPixel/s for the AMD Ryzen Z2 A GPU, a difference of roughly 49.6 GPixel/s or about 194% higher. This advantage comes directly from the Intel part having 32 ROPs versus 16 ROPs, combined with its higher boost clock of 2350 MHz versus 1600 MHz.

Texture rate follows the same pattern. Intel delivers 150.4 GTexel/s against AMD's 51.20 GTexel/s, a gap of about 99.2 GTexel/s or roughly 194% higher. The Intel part's 64 TMUs versus 32 TMUs account for this, with the clock advantage amplifying the unit count difference.

In FP32 compute, Intel posts 4.813 TFLOPS versus 1.638 TFLOPS for AMD. This is a difference of 3.175 TFLOPS, or approximately 194% higher for Intel. The FP16 comparison shows 9.626 TFLOPS for Intel and 3.277 TFLOPS for AMD, a gap of 6.349 TFLOPS, again roughly 194% higher. The proportional consistency across pixel rate, texture rate, and both compute formats indicates that the Intel part's advantage is uniform across all shader and fixed-function units, driven by its doubled unit counts and higher boost clock.

The AMD Ryzen Z2 A GPU's wins are less about peak performance and more about operational characteristics. Its base clock of 1000 MHz is 700 MHz higher than Intel's 300 MHz base, meaning it does not need to ramp as aggressively to reach its operating point. Its 15 W TDP is 20 W lower than Intel's 35 W TDP, a substantial reduction for thermally constrained portable devices. Its dedicated 16 GB LPDDR5 memory with a fixed 102.4 GB/s bandwidth removes any dependency on host system memory configuration, whereas the Intel part's bandwidth is system dependent and could vary widely across different laptops.

In the absence of measured benchmark scores, these recorded specifications indicate that the Intel Arc 140T Mobile is the higher-performing part across every throughput metric, while the AMD Ryzen Z2 A GPU offers a lower-power, self-contained memory solution that trades raw speed for efficiency and predictability. Both parts sit at the 50th percentile among all GPUs in the database, reflecting their mid-tier positioning in the broader graphics landscape.
