AMD Radeon RX 460 Mobile

The AMD Radeon RX 460 Mobile is a GCN 4.0 architecture part built on the Baffin chip, manufactured on a 14 nm process at GlobalFoundries. It integrates 3,000 million transistors on a 123 mm² die, resulting in a transistor density of 24.4M per mm². This analysis focuses strictly on the data available for this mobile graphics processor, which sits at the 50th percentile against all GPUs in the database, indicating it is positioned at the median of the performance spectrum.

Memory Subsystem

The RX 460 Mobile is equipped with 4 GB of GDDR5 memory, a configuration that was standard for its generation. The memory interface is a 128-bit bus, which is a moderate width for a mobile part of this class. The memory clock runs at 1250 MHz, translating to 5 Gbps effective data rate. When combined with the 128-bit bus, this yields a total memory bandwidth of 80.00 GB/s.

This bandwidth figure is a critical constraint for high-resolution gaming. At 1080p, the 80.00 GB/s is generally sufficient to feed the GPU’s 896 shading units without creating a severe bottleneck in most titles. However, the data suggests that as resolution increases, the demand on memory bandwidth scales non-linearly. At 1440p or higher, the 80.00 GB/s throughput will likely become a limiting factor, causing frame pacing issues in texture-heavy scenes. The 4 GB VRAM capacity is also a consideration; while adequate for 1080p textures in older titles, it may be insufficient for maximum texture quality in more recent releases that require more than 4 GB of frame buffer. The pixel rate of 18.88 GPixel/s and texture rate of 66.08 GTexel/s are consistent with a 16 ROP and 56 TMU configuration, respectively, meaning the memory subsystem is balanced for 1080p throughput rather than high-resolution fill-rate demands.

Who Should Consider It

Given the benchmark percentile of 50, the RX 460 Mobile is a median performer. The data indicates it is best suited for 1080p gaming with medium to high settings in esports and older AAA titles. Users targeting 60 frames per second in competitive shooters will find the 2.115 TFLOPS of FP32 compute adequate, as these titles are typically less demanding on both compute and memory bandwidth. The 1:1 FP16 to FP32 ratio of 2.115 TFLOPS does not offer any compute advantage for standard gaming workloads.

For users with a 1440p monitor, the data suggests this GPU is not a recommended choice. The combination of 80.00 GB/s bandwidth and 16 ROPs will struggle to maintain playable frame rates in modern games at that resolution, even with settings reduced. The card is also not suitable for high-refresh-rate 1080p gaming (144Hz+), as the raw pixel throughput of 18.88 GPixel/s caps the fill-rate ceiling. The 50th percentile ranking implies that half of all GPUs in the database outperform it, making it a sensible choice only for a secondary machine, a light gaming laptop, or for users whose primary workload is not graphically intensive. The 4 GB VRAM is a hard limit; users must be willing to lower texture quality in games that exceed this capacity to avoid stuttering.

Benchmark Performance

The benchmark data for this specific SKU is sparse, with an average benchmark score of 0 and no entries in the nearestRivals array. This absence of direct comparative scores makes a quantitative delta analysis impossible. However, the 50th percentile ranking against all GPUs provides a contextual anchor. This score indicates that in aggregate, it performs better than roughly half of all GPUs ever benchmarked in the database, which includes integrated graphics, older discrete parts, and entry-level mobile chips.

Without nearestRivals data, we cannot state specific percentage deltas against named competitors. The performance profile must be inferred from the internal specifications. The FP32 throughput of 2.115 TFLOPS, combined with a texture rate of 66.08 GTexel/s, places it in a performance class that is distinctly below high-end Polaris parts but above the lowest tier of dedicated graphics. The 50th percentile figure is the only concrete performance metric available, and it suggests that while not a top-tier part, it is by no means a bottom-feeder. Users should expect consistent 1080p performance in less demanding titles, but the lack of rival scores means we cannot provide a head-to-head percentage advantage or disadvantage. The data simply shows a mid-pack position.

FAQ

Q: What is the memory bandwidth of the AMD Radeon RX 460 Mobile?

A: The GPU has a memory bandwidth of 80.00 GB/s, derived from a 128-bit bus and 5 Gbps effective GDDR5 memory speed.

Q: Does this GPU support hardware ray tracing?

A: No. The FACT PACK lists no ray tracing cores (rtCores: null) and no tensor cores (tensorCores: null). It relies on traditional rasterization through its GCN 4.0 architecture.

Q: What is the thermal design power (TDP) of this mobile GPU?

A: The TDP is rated at 55 W. The card uses an MXM Module slot width and does not require any power connectors, indicating it draws power solely from the MXM slot.

Q: What is the transistor count and die size?

A: The Baffin chip contains 3,000 million transistors on a die size of 123 mm², fabricated on a 14 nm process at GlobalFoundries.

Q: Which DirectX version is supported?

A: The GPU supports DirectX 12 (12_0), along with OpenGL 4.6 and Vulkan 1.3.

Q: What is the boost clock speed?

A: The base clock is 1000 MHz, and the boost clock is 1180 MHz.

Ray Tracing and Feature Set

The RX 460 Mobile does not include any ray tracing acceleration hardware. The FACT PACK explicitly lists rtCores as null and tensorCores as null. This means all rendering is done via the traditional GCN 4.0 shader pipeline, which relies on the 896 shading units. Consequently, any ray-traced effects in games must be computed on the shader units, which would incur a significant performance penalty. Given the 2.115 TFLOPS FP32 throughput, the GPU is not suitable for real-time ray tracing at playable frame rates, even at 1080p with low ray-tracing settings.

The feature set is defined by its API support rather than dedicated hardware. It supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. This API coverage ensures compatibility with modern game engines and allows for low-level access to the hardware in Vulkan and DX12 titles. The lack of tensor cores also means that any AI-accelerated features, such as DLSS (which is Nvidia-specific), are not applicable. In terms of display outputs, the specification is "Portable Device Dependent," meaning the outputs are determined by the laptop manufacturer rather than the GPU itself. The bus interface is MXM-B (3.0), which is a standard for mobile modules.

Power and Cooling

The power profile of the RX 460 Mobile is modest, with a TDP of 55 W. This is a relatively low figure for a discrete GPU, making it suitable for thinner laptops. The card is an MXM Module, which dictates the physical form factor and cooling solution design. The slot width is listed as "MXM Module," and it uses the MXM-B (3.0) bus interface.

Crucially, the power connectors field is "None." This indicates that the GPU receives all its power through the MXM slot itself, with no auxiliary 6-pin or 8-pin connectors required. This simplifies laptop design and reduces the peak power draw that the system must handle. The absence of a suggested PSU (suggestedPsu: null) is expected for a mobile part, as power is supplied by the laptop's AC adapter and internal power delivery system. The 55 W TDP means that a cooling solution consisting of a modest heatsink and fan should be sufficient to manage thermals. The production status is "End-of-life," and the release date was August 7, 2016, with the predecessor listed as "Gem System" and the successor as "Navi Mobile." The low power draw makes it an efficient part, but the 55 W envelope also limits its maximum performance ceiling compared to higher-TDP mobile GPUs.
