NVIDIA RTX A4000 Max-Q

The NVIDIA RTX A4000 Max-Q is a professional Ampere-generation GPU built around the GA104 chip. Samsung produces the chip on an 8 nm process, and the die contains 17,400 million transistors across 392 mm², for a density of 44.4M transistors per square millimeter. The GPU has 5120 shading units, 160 texture mapping units, 80 ROPs, 40 RT cores, and 160 tensor cores. Memory is 8 GB of GDDR6 on a 256-bit bus, with a memory clock of 1375 MHz and an effective data rate of 11 Gbps, for 352.0 GB/s of bandwidth. Base clock is 780 MHz, boost clock is 1395 MHz, and FP32 and FP16 compute are both 14.28 TFLOPS. The TDP is 80 W, there are no auxiliary power connectors, and the bus interface is PCIe 4.0 x16. Display outputs are portable-device dependent. The product was released on April 11, 2021, is listed as end-of-life, and sits at the 50th percentile of all GPUs in the database.

Power and Cooling

The A4000 Max-Q has a TDP of 80 W. That single figure is the primary thermal anchor for the entire board. The FACT PACK lists no suggested PSU, and the power connectors field is "None." No length, height, width, or slot width values are provided, so the mechanical and thermal implementation is left to the host platform. With 17,400 million transistors on a 392 mm² die, the transistor density is 44.4M per square millimeter, which describes how concentrated the heat source is. At 80 W, the cooling solution must dissipate that concentrated heat within a portable device enclosure, but the data does not specify any particular cooler type, size, or airflow requirement.

The base clock is 780 MHz and the boost clock is 1395 MHz. The difference between those two states shows the operating range available under load, and the actual sustained clock will depend on the host system's thermal headroom and power management. Because there are no auxiliary power connectors, the host platform is responsible for supplying all power to the GPU. The absence of a suggested PSU in the data reinforces that this is not a standalone desktop card; it is a board designed for tightly integrated systems where the chassis and motherboard determine the power delivery path. The 80 W TDP is deliberately modest relative to the listed compute rates, indicating a power-constrained configuration rather than one optimized for maximum boost behavior. The process data — Samsung 8 nm, 17,400 million transistors, 392 mm² die — supplies the manufacturing context, but the actual cooling performance is not measured in the record.

Ray Tracing and Feature Set

The A4000 Max-Q includes dedicated ray tracing hardware in the form of 40 RT cores. It also includes 160 tensor cores for tensor-accelerated workloads. The FP16 compute rate is 14.28 TFLOPS, and the pack lists it as 1:1 with FP32, meaning there is no half-rate penalty for FP16 shader and compute paths. This is a notable feature for workloads that can use reduced precision, because the throughput does not drop when switching from FP32 to FP16.

The API support covers DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. DirectX 12 Ultimate with feature level 12_2 is the DirectX feature level listed in the record, and it provides the API foundation for current-generation graphics features. Vulkan 1.4 is listed as a cross-platform low-level API, and OpenGL 4.6 remains present for compatibility with workstation software. The API set spans both proprietary and cross-platform paths, so the GPU is not limited to a single software ecosystem.

The rasterization feature set is also defined by the fixed-function hardware: 5120 shading units, 160 TMUs, and 80 ROPs. From those counts, the pixel rate is 111.6 GPixel/s and the texture rate is 223.2 GTexel/s. These rates set the fill limits for pixel-heavy and texture-heavy scenes, while the RT and tensor cores handle workloads beyond traditional rasterization. The data does not include any benchmark entries, so the practical performance of these feature blocks is not validated by measured workloads.

Memory Subsystem

The memory configuration is 8 GB of GDDR6 on a 256-bit bus. The memory clock is 1375 MHz, and the effective data rate is 11 Gbps. Those specifications produce a bandwidth figure of 352.0 GB/s. For high-resolution tasks, bandwidth and capacity are the two constraints that matter most. The 256-bit bus is the structural path that moves data between memory and the compute units, and the 11 Gbps effective rate is the per-pin speed multiplied across that bus to reach the 352.0 GB/s figure.

The 8 GB capacity is the upper bound for the local working set. Scenes, textures, geometry buffers, and ray tracing acceleration structures must fit within that capacity, and the data does not describe any fallback path for data that exceeds it. With 5120 shading units and 160 TMUs, the texture rate is 223.2 GTexel/s; with 80 ROPs, the pixel rate is 111.6 GPixel/s. These output rates matter for high-resolution rendering, but they depend on memory bandwidth to feed them. The combination of an 8 GB GDDR6 pool, a 256-bit bus, and 352.0 GB/s of bandwidth suggests a design aimed at high-resolution professional workloads, though no actual high-resolution scores are present in the benchmark data.

How It Compares

The nearestRivals array in the FACT PACK is empty. There are no rival names, no rival scores, and no deltaPct values to quote. The benchmarks array is also empty, and the average benchmark score field is 0. Therefore, the A4000 Max-Q has no measured performance aggregate in this database, and direct comparison to any specific competitor is not possible.

The only ranking data is percentileVsAllGpus: 50. This places the product at the midpoint of the database distribution. It is a position, not a workload-derived score. The 50th percentile means the product is in the middle of the database ranking, with no evidence from the record that it sits above or below any particular named GPU. The empty benchmarks array supports the interpretation that this percentile is a placeholder rather than a result of tested workloads.

In terms of product succession, the A4000 Max-Q follows the Quadro Turing-M generation and precedes the Ada-MW generation. Those are predecessor and successor entries in the data, not scored rivals, and no performance gap is quantified for either transition. Without nearest rivals or benchmark scores, the only useful comparison is internal: it belongs to the Ampere-generation mobile workstation line and is placed at the 50th percentile of all GPUs in the database.

Who Should Consider It

Because there are no benchmark scores, any consideration must be based on the documented specifications. The A4000 Max-Q is defined by an 80 W TDP, no auxiliary power connectors, portable-device-dependent display outputs, and an Ampere feature set with 40 RT cores and 160 tensor cores. That combination points toward mobile workstation users who need ray tracing and tensor capabilities in a power-constrained chassis.

The 8 GB GDDR6 frame buffer and 352.0 GB/s bandwidth are appropriate for high-resolution workloads whose working sets fit within 8 GB. The 5120 shading units provide 14.28 TFLOPS of FP32 compute, and the 1:1 FP16 rate means half-precision workloads can run at the same peak throughput. The API support for DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6 covers a broad range of modern software interfaces.

The 50th percentile placement, however, signals a mid-range position rather than a top-tier one. The product is end-of-life and was released on April 11, 2021, so it is not a current-generation selection. The lack of a suggested PSU and the absence of auxiliary power connectors indicate that the GPU is intended for controlled system integration, not installation into arbitrary platforms. Users who already have a portable workstation that matches this power and connector profile are the audience implied by the data. Users who require benchmark-validated performance or named rival comparisons will not find that evidence in the FACT PACK, because no such data exists.
