AMD Radeon RX 480 Mobile

The AMD Radeon RX 480 Mobile is a Polaris-generation mobile GPU built on the Ellesmere chip and GCN 4.0 architecture. It is fabricated on GlobalFoundries' 14 nm process, integrating 5,700 million transistors on a 232 mm² die with a transistor density of 24.6M / mm². The device was released on 2016-08-03, is listed as end-of-life, and belongs to the generation labeled Polaris Mobile (RX M400). The module uses an MXM-B (3.0) bus interface and an MXM Module slot width, has a 100 W TDP, lists no power connectors, and its display outputs are portable-device dependent. Clock behavior is specified as 1000 MHz base and 1077 MHz boost, with memory at 2000 MHz / 8 Gbps effective.

Memory Subsystem — VRAM size/type, bus width, bandwidth and what it means for high resolutions

The RX 480 Mobile is equipped with 8 GB of GDDR5 on a 256-bit bus. The memory clock is listed as 2000 MHz, or 8 Gbps effective, and the resulting bandwidth is 256.0 GB/s. For high-resolution rendering, the 8 GB capacity is the most direct asset: larger frame buffers and high-resolution textures can be kept resident without as much pressure on memory management. The 256-bit bus and 256.0 GB/s bandwidth govern how quickly texel and pixel data can move between memory and the compute units. The listed pixel rate of 34.46 GPixel/s and texture rate of 155.1 GTexel/s indicate the consumption rates that the memory system must feed.

A 256.0 GB/s stream is a substantial data path for a mobile Polaris part, and the 8 GB frame buffer is a large allocation for a 2016-era mobile GPU. The relationship between fill rate and bandwidth matters at high resolutions because more pixels are shaded per frame and more texture fetches are issued per visible surface. The record does not include benchmark scores, so the practical high-resolution frame rate cannot be derived from this data; what can be stated is the memory configuration itself: 8 GB, GDDR5, 256 bit, 256.0 GB/s, and an 8 Gbps effective signaling rate.

Who Should Consider It

The data set has no benchmark scores and no nearestRivals entries, so any consideration list must be spec-based rather than score-based. The FP32 throughput is 4.963 TFLOPS, with FP16 also 4.963 TFLOPS at a 1:1 ratio; pixel fill is 34.46 GPixel/s and texture fill is 155.1 GTexel/s. These throughput values describe a mobile MXM module intended to be slotted into portable systems rather than a desktop card. Because the bus interface is MXM-B (3.0), the slot width is MXM Module, and display outputs are portable-device dependent, only systems built around an MXM socket and compatible output topology can use it.

The 100 W TDP and the absence of additional power connectors are the power-related facts in the record. The 8 GB GDDR5 memory and 256.0 GB/s bandwidth suggest a capability for high-resolution assets, but the precise in-game settings cannot be stated from this record. No measured scores exist, so no resolution/settings recommendation can be grounded in benchmark results. The percentileVsAllGpus value of 50 places the GPU at the midpoint of the database distribution, but without an avgBenchmarkScore, that percentile is not a performance guideline. A user with an MXM-B portable system and a need for a GCN 4.0, Polaris Mobile (RX M400) module would be the relevant audience, assuming the host system's display output requirements align with the portable-device-dependent outputs.

Benchmark Performance

In this record, the nearestRivals array is empty. There are therefore no rival names and no deltaPct values that can be used for percentage comparisons. The benchmarks array is also empty, and avgBenchmarkScore is 0, so no measured score is available for the RX 480 Mobile. The only rank information is percentileVsAllGpus = 50, which places the device at the midpoint of the all-GPU distribution in the database. Without a benchmark score, that percentile cannot be converted into an absolute performance figure or a rival delta.

The specification-derived throughput values are 4.963 TFLOPS FP32, 4.963 TFLOPS FP16 at a 1:1 ratio, 34.46 GPixel/s, and 155.1 GTexel/s. These are not benchmark scores, and the data set does not allow translating them into percentage deltas against named alternatives. Any statement such as “X% faster than …” would require nearestRivals data that is absent. The empty benchmarks array and avgBenchmarkScore of 0 indicate that no measured result feeds the percentile. Consequently, the data supports architectural and memory-system analysis but not comparative performance claims.

FAQ

Q: What memory configuration is listed for the AMD Radeon RX 480 Mobile?

A: The GPU uses 8 GB of GDDR5 on a 256-bit bus, with a memory clock of 2000 MHz / 8 Gbps effective and a bandwidth of 256.0 GB/s.

Q: What API support is specified?

A: The record lists DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3.

Q: What are the core and throughput counts?

A: There are 2304 shading units, 144 texture mapping units, and 32 render output units. FP32 compute is 4.963 TFLOPS, FP16 is also 4.963 TFLOPS at a 1:1 ratio, pixel rate is 34.46 GPixel/s, and texture rate is 155.1 GTexel/s.

Q: What process and clock details are in the data?

A: The chip is Ellesmere, built on GlobalFoundries' 14 nm process, with a die size of 232 mm² and 5,700 million transistors. Base clock is 1000 MHz and boost clock is 1077 MHz.

Q: Is this GPU still in production?

A: No, it is listed as end-of-life. Its release date is 2016-08-03, with predecessor “Gem System” and successor “Navi Mobile”.

Q: Are there ray tracing or tensor core counts in the record?

A: No; the rtCores and tensorCores fields are null. The architecture is GCN 4.0, but no dedicated RT or tensor core quantities are provided.

Ray Tracing and Feature Set

The record does not populate rtCores or tensorCores, so no hardware ray tracing core count or tensor core count can be attributed to the RX 480 Mobile from this data. The feature set is defined by the GCN 4.0 architecture and the Polaris Mobile (RX M400) generation, with the Ellesmere chip at its core. Compute features include 2304 shading units, 144 TMUs, and 32 ROPs, producing the listed FP32 and FP16 rates of 4.963 TFLOPS each at a 1:1 ratio.

API support extends to DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, which is the formal compatibility scope listed for this product. The absence of RT and tensor core counts means that ray tracing or tensor-acceleration behavior cannot be quantified; the data only supports statements about the conventional GCN 4.0 feature set. Additional integration facts are the 14 nm GlobalFoundries process, 5,700 million transistors, 232 mm² die, 100 W TDP, MXM-B (3.0) interface, and portable-device-dependent display outputs.
