NVIDIA RTX A4 Mobile

The NVIDIA RTX A4 Mobile is an Ampere-generation mobile workstation GPU built for laptops and portable devices, utilizing the GA107 chip fabricated on Samsung's 8 nm process. With 8,700 million transistors packed into a 200 mm² die, the data shows a part designed for efficiency and portability rather than absolute top-tier performance. Its position at the 50th percentile of all GPUs in the benchmark database places it firmly in the mid-range of the performance spectrum.

Benchmark Performance

The RTX A4 Mobile's functional performance is defined by its 2,048 shading units, operating at a base clock of 1297 MHz and a boost clock of 1770 MHz. This configuration yields a peak FP32 throughput of 7.250 TFLOPS. In practical terms, this is a modest figure for a mobile workstation GPU, indicating a capability suited for entry-level professional tasks and 1080p-class workloads rather than compute-heavy rendering or high-resolution simulation.

The data indicates a balanced compute profile: the FP16 rate is also 7.250 TFLOPS (1:1), meaning there is no dedicated half-precision acceleration that would benefit AI inference or certain scientific workloads. This is a significant architectural note, unlike some Ampere variants that double FP16 throughput via tensor cores, the A4's raw FP16 and FP32 are identical, suggesting the tensor cores are the primary avenue for accelerated AI work. The texture fill rate stands at 113.3 GTexel/s, and the pixel rate is 56.64 GPixel/s, derived from 64 texture mapping units and 32 render output units. These figures are consistent with a 128-bit memory interface and a 4 GB GDDR6 frame buffer.

The memory subsystem delivers 224.0 GB/s of bandwidth, a figure constrained by the 128-bit bus and 1750 MHz memory clock (14 Gbps effective). For a GPU of this class, the bandwidth is adequate for 1080p gaming and light 3D modeling, but it will become a bottleneck in texture-heavy scenes or when working with large datasets. The 4 GB capacity is a notable limitation; modern professional applications and games often exceed this at higher settings, which will force reliance on lower resolutions or reduced texture quality.

Ray Tracing and Feature Set

The RTX A4 Mobile includes dedicated hardware for ray tracing and AI acceleration, a hallmark of the Ampere architecture. It is equipped with 16 RT cores and 64 tensor cores. The presence of these cores is a clear generational step over its Quadro Turing-M predecessor, enabling hardware-accelerated ray-traced effects in supported applications. However, given the GPU's overall throughput, the RT core count is low, suggesting that ray tracing performance will be functional but not a primary strength; users should expect playable frame rates only at lower resolutions and with reduced ray-tracing complexity.

On the API front, the GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The DirectX 12 Ultimate designation is crucial, as it guarantees support for features like DirectX Raytracing (DXR) and Variable Rate Shading, aligning with modern gaming and rendering standards. Vulkan 1.4 support further ensures compatibility with a wide range of cross-platform engines and applications. The 64 tensor cores provide the foundation for DLSS (Deep Learning Super Sampling) and similar AI-based upscaling technologies, which can partially offset the raw performance limitations in ray-traced titles.

The display output is listed as "Portable Device Dependent," meaning the connector and output capabilities are determined by the laptop manufacturer, not the GPU itself. The bus interface is PCIe 4.0 x8, which provides sufficient bandwidth for the 4 GB frame buffer without being a bottleneck, though it is half the lanes of a full x16 connection.

Who Should Consider It

Benchmark results position the RTX A4 Mobile as a solution for users whose primary workload is mainstream 1080p gaming or entry-level professional design. The 7.250 TFLOPS of FP32 compute and 224.0 GB/s memory bandwidth indicate that at 1080p with medium-to-high settings, the GPU can deliver smooth frame rates in most contemporary titles. Users targeting 1440p will need to adjust settings to medium or lower, and 4K is largely outside the capable envelope for this part, particularly with ray tracing enabled.

For professional use, the 4 GB VRAM is the defining constraint. It suits basic CAD, 2D drafting, and light 3D modeling, but it is insufficient for complex scenes, high-resolution textures, or large simulation datasets. The inclusion of 16 RT cores and 64 tensor cores adds future-proofing for software that increasingly leverages hardware-accelerated ray tracing and AI denoising, but the limited memory and raw compute will cap the complexity of those workloads. This is a GPU for the mobile professional who needs certified-driver stability and moderate acceleration, not for a compute node or a high-end rendering workstation.

Power and Cooling

The RTX A4 Mobile is configured as an IGP (Integrated Graphics Processor) with a slot width of "IGP," meaning it is designed to be soldered directly onto the motherboard rather than installed as a discrete card. Consequently, it has no power connectors and relies entirely on the host laptop's power delivery system. The data does not specify a TDP or a suggested PSU, which is typical for mobile parts where system-level power budgets are set by the OEM.

The absence of a TDP figure makes direct power consumption analysis impossible, but the architecture and clock speeds suggest a modest power draw, likely within the range of a thin-and-light workstation. The cooling solution is entirely dependent on the laptop chassis design; the GPU's thermal behavior cannot be assessed in isolation from the host system. Users should ensure their chosen laptop provides adequate cooling for sustained workloads, as the boost clock of 1770 MHz is only sustainable if thermal headroom is available.

How It Compares

The the benchmark database provides no direct nearest rivals for the RTX A4 Mobile, which is an uncommon situation in the database. This absence of comparative data means that an objective performance ranking against similar-generation mobile GPUs cannot be established from the available facts. However, the 50th percentile ranking across all GPUs gives a general reference point, indicating that half of all GPUs tested are faster and half are slower.

Without specific rival data, the analysis must rely on the internal characteristics of the RTX A4 Mobile itself. Its predecessor, the Quadro Turing-M, represents the prior generation; the A4's Ampere architecture brings dedicated RT and tensor cores, a clear feature advantage. Its successor, Ada-MW, would be expected to outperform it, but no scores are provided. Given the production status of "End-of-life" and a release date of April 2021, the RTX A4 Mobile is a legacy part. For users comparing systems, the data indicates that any modern mid-range or higher mobile GPU would likely offer superior raw performance, but the A4 retains relevance in the context of older, certified workstation laptops where driver stability and feature support for legacy applications are paramount.
