AMD Ryzen Z2 GPU vs Intel Arc 140T Mobile Comparison

Where Each One Wins

The AMD Ryzen Z2 GPU and Intel Arc 140T Mobile serve different primary roles, and the recorded specifications point to a clear split in intended workloads. The AMD part is a discrete-class console GPU with 16 GB of dedicated LPDDR5X memory, a 128-bit bus, and 119.9 GB/s of bandwidth. The Intel part is an integrated GPU (IGP) that shares system memory, with its bandwidth listed as “System Dependent.” That distinction alone drives most of the use-case separation.

For sustained throughput in rasterization and compute-heavy tasks, the AMD Ryzen Z2 GPU holds the advantage. Its FP32 output is 8.294 TFLOPS, while the Intel Arc 140T Mobile delivers 4.813 TFLOPS. That is a 72% lead for AMD in single-precision compute, which directly translates to faster shader work in traditional games and GPU-accelerated applications that rely on FP32 math. The AMD part also has a higher pixel rate, 86.40 GPixel/s versus 75.20 GPixel/s, indicating stronger fill-rate performance for resolution-bound scenes.

The Intel Arc 140T Mobile, however, wins in texture throughput and in half-precision compute. Its texture rate is 150.4 GTexel/s, which is 16% higher than AMD’s 129.6 GTexel/s. In FP16, Intel reaches 9.626 TFLOPS using a 2:1 rate, compared to AMD’s 8.294 TFLOPS at a 1:1 ratio. That makes the Intel part more capable for workloads that can use packed half-precision math, such as certain machine-learning inference passes or media processing filters. The Intel part also has more shading units (1024 versus 768) and more texture mapping units (64 versus 48), which explains its texture-rate advantage despite a lower clock.

For memory capacity, the AMD Ryzen Z2 GPU offers 16 GB of dedicated VRAM, which is a hard advantage for large assets, high-resolution textures, or GPU compute buffers that cannot fit in shared memory. The Intel Arc 140T Mobile uses “System Shared” memory, meaning its effective capacity is whatever the host system allocates, and its bandwidth depends entirely on the platform’s memory configuration. That makes the Intel part more flexible in terms of total memory pool but less predictable for peak bandwidth.

Power and integration also separate the two. The AMD part has a 28 W TDP, while the Intel part carries a 35 W TDP. The Intel part is an IGP with no power connectors, and its display outputs are “Portable Device Dependent.” The AMD part has a single USB Type-C display output and no power connectors either, but it is not classified as an IGP. The AMD chip is built on TSMC’s 4 nm process, while the Intel chip uses TSMC’s 5 nm node. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity is complete.

Architecture Differences

The AMD Ryzen Z2 GPU is built on the RDNA 3.0 architecture, with the chip codenamed Hawk Point. It uses a 4 nm TSMC process and integrates 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6M per mm². The Intel Arc 140T Mobile uses the Xe-LPG+ architecture on the Arrow Lake-H chip, fabricated on a 5 nm TSMC process. Intel’s transistor count and die size are listed as “unknown,” so no direct density comparison is possible from the recorded data.

The AMD GPU has 768 shading units, 48 TMUs, and 32 ROPs. It also includes 12 ray tracing cores. The Intel GPU has 1024 shading units, 64 TMUs, and 32 ROPs, with 8 ray tracing cores. So Intel has 33% more shading units and 33% more TMUs, but AMD has 50% more ray tracing cores. That suggests AMD’s ray tracing hardware is denser per shader, while Intel relies on a wider shader array for raw throughput.

Memory architecture is fundamentally different. AMD uses 16 GB of LPDDR5X on a 128-bit bus, with memory clocked at 937 MHz (7.5 Gbps effective) for a peak bandwidth of 119.9 GB/s. Intel uses “System Shared” memory, with type, bus width, and bandwidth all listed as “System Shared” or “System Dependent.” That means Intel’s memory performance is not fixed; it varies with the host platform’s memory speed and channel configuration.

Clocks also diverge sharply. The AMD part has a base clock of 800 MHz and a boost clock of 2700 MHz. The Intel part has a base clock of 300 MHz and a boost clock of 2350 MHz. Despite the lower boost clock, Intel’s wider shader array compensates in texture-heavy workloads. AMD’s higher boost clock plus its 1:1 FP16/FP32 ratio gives it a more balanced compute profile.

Both GPUs are listed as “Active” in production status. The AMD part’s release date is 2024-12-31, while the Intel part’s release date is 2025-01-12, so they are effectively contemporaries. The Intel part has a predecessor listed as “HD Graphics-M,” while AMD has no predecessor or successor recorded. Neither part has a launch MSRP in the database.

The Intel part is explicitly an “IGP” with a slot width of “IGP” and a bus interface of “IGP.” The AMD part has no slot width or bus interface listed, and its display output is a single USB Type-C. That reinforces the positioning: AMD is a standalone GPU for portable consoles or handhelds, while Intel is an integrated solution for laptops or mini PCs.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for these two GPUs, and neither has an average benchmark score or nearest rival entries. However, the recorded specification sheet provides enough data to compare their theoretical peak performance across several metrics.

In FP32 compute, the AMD Ryzen Z2 GPU delivers 8.294 TFLOPS. The Intel Arc 140T Mobile delivers 4.813 TFLOPS. That means AMD is 72% ahead in single-precision floating-point throughput. This is the largest measured difference between the two, and it directly impacts shader-bound gaming scenes and compute workloads like physics simulation or video encoding filters that use FP32.

In texture rate, Intel reverses the result. The Intel part reaches 150.4 GTexel/s, while AMD reaches 129.6 GTexel/s. Intel is 16% ahead. This advantage comes from having 64 TMUs versus 48 TMUs, even though AMD’s boost clock is 350 MHz higher. For games that are fill-rate limited by texture sampling, such as scenes with heavy anisotropic filtering or detailed surfaces, Intel’s wider TMU array provides a measurable edge.

In pixel rate, AMD leads again. AMD’s 86.40 GPixel/s is 15% higher than Intel’s 75.20 GPixel/s. Both parts have 32 ROPs, so AMD’s advantage comes from its higher boost clock (2700 MHz versus 2350 MHz). This makes AMD better suited for resolution scaling or overdraw-heavy effects like shadows and post-processing.

In half-precision compute, Intel takes the lead. Intel’s FP16 output is 9.626 TFLOPS at a 2:1 ratio, while AMD’s FP16 output is 8.294 TFLOPS at a 1:1 ratio. Intel is 16% ahead in FP16. This matters for AI inference, certain image processing pipelines, and any workload that can exploit packed half-precision arithmetic. AMD’s 1:1 ratio means its FP16 performance is identical to its FP32 performance, which is simpler but less efficient for dedicated FP16 tasks.

Memory bandwidth is a clear AMD win. AMD’s 119.9 GB/s is a fixed, dedicated figure. Intel’s bandwidth is “System Dependent,” meaning it could be higher or lower depending on the host system’s memory configuration. In a best-case scenario with fast LPDDR5X or DDR5, Intel could potentially exceed 119.9 GB/s, but the database does not record a fixed number for Intel, so the comparison remains speculative. For guaranteed peak bandwidth, AMD’s dedicated 128-bit memory bus is more reliable.

Ray tracing hardware also favors AMD. The AMD part has 12 ray tracing cores versus Intel’s 8, a 50% advantage. Both support DirectX 12 Ultimate (12_2), so ray tracing is enabled on both, but AMD’s higher core count suggests stronger ray tracing throughput per clock. No benchmark scores are recorded, so this remains a structural advantage rather than a measured one.

The Verdict

The data points to a straightforward split. The AMD Ryzen Z2 GPU is the stronger choice for FP32 compute, pixel fill rate, dedicated memory capacity, and ray tracing core count. It has a 72% lead in FP32 TFLOPS, a 15% lead in pixel rate, and 50% more ray tracing cores. Its 16 GB of dedicated LPDDR5X memory with a fixed 119.9 GB/s bandwidth removes any dependency on system memory configuration.

The Intel Arc 140T Mobile is the better option for texture throughput and half-precision compute. It has a 16% lead in texture rate and a 16% lead in FP16 TFLOPS. Its 1024 shading units and 64 TMUs give it a wider parallel array, which is useful for texture-bound workloads and FP16-friendly applications. As an IGP, it also integrates directly into a host processor, eliminating the need for a separate GPU slot or power connectors.

For gaming, AMD’s higher FP32 throughput and pixel rate likely translate to better rasterization performance in conventional titles. The larger dedicated memory pool also avoids the risk of system memory contention. For compute tasks that can use FP16, Intel’s 2:1 ratio provides higher peak throughput, but that advantage only materializes if the software is written to use packed FP16 math.

The Intel part has a higher TDP at 35 W versus AMD’s 28 W, so it consumes more power for its lower FP32 output. That makes AMD more power-efficient per FP32 FLOP, though Intel’s higher texture rate per watt is plausible given the data. Neither part has a launch MSRP, so no price comparison is possible.

Users who need a self-contained GPU with guaranteed memory bandwidth and strong FP32 should select the AMD Ryzen Z2 GPU. Users who require an integrated solution with high texture throughput and FP16 capability, and who are comfortable with system-shared memory, should select the Intel Arc 140T Mobile.
