AMD Radeon 620 Mobile Specifications

Radeon 620 Mobile GPU Core

Shader units and compute resources

The AMD Radeon 620 Mobile GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.

620 Mobile Clock Speeds

GPU and memory frequencies

Clock speeds directly impact the Radeon 620 Mobile's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The Radeon 620 Mobile by AMD dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.

AMD's Radeon 620 Mobile Memory

VRAM capacity and bandwidth

VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The Radeon 620 Mobile's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.

Radeon 620 Mobile by AMD Cache

On-chip cache hierarchy

On-chip cache provides ultra-fast data access for the 620 Mobile, reducing the need to fetch data from slower VRAM. L1 and L2 caches store frequently accessed data close to the compute units. AMD's Infinity Cache (L3) dramatically increases effective bandwidth, improving GPU benchmark performance without requiring wider memory buses. Larger cache sizes help maintain high frame rates in memory-bound scenarios and reduce power consumption by minimizing VRAM accesses.

620 Mobile Theoretical Performance

Compute and fill rates

Theoretical performance metrics provide a baseline for comparing the AMD Radeon 620 Mobile against other graphics cards. FP32 (single-precision) performance, measured in TFLOPS, indicates compute capability for gaming and general GPU workloads. FP64 (double-precision) matters for scientific computing. Pixel and texture fill rates determine how quickly the GPU can render complex scenes. While real-world GPU benchmark results depend on many factors, these specifications help predict relative performance levels.

About AMD Radeon 620 Mobile

The AMD Radeon 620 Mobile is an end-of-life mobile IGP based on the Polaris 24 chip and GCN 3.0 architecture. It is manufactured by TSMC on a 28 nm process with 1,550 million transistors on a 125 mm² die, giving a transistor density of 12.4M / mm². The GPU is listed under the Polaris Mobile (M600) generation, was released on 2019-05-12, and uses a PCIe 3.0 x8 bus interface. The memory subsystem consists of 2 GB GDDR5 on a 64-bit bus with a 1000 MHz memory clock (4 Gbps effective) and 32.00 GB/s bandwidth. Shading hardware includes 384 shading units, 24 TMUs, and 8 ROPs. The API list covers DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170.

Benchmark Performance

The central fact about this GPU is that there are no measured benchmark scores. The benchmarks array is empty, and the average benchmark score is 0. The percentile field places the GPU at 50 among all GPUs in the database, but with no score entries that value cannot be read as a validated performance rank. No nearest rivals are listed, so exact percentage deltas against competing GPUs cannot be computed from this data.

The concrete performance figures available are theoretical rates rather than test results. FP32 throughput is 706.6 GFLOPS, texture rate is 22.08 GTexel/s, and pixel rate is 7.360 GPixel/s. These are the raw limits of the 384 shading units, 24 TMUs, and 8 ROPs. The 8 ROP count and the 7.360 GPixel/s pixel rate indicate a limited fill-rate ceiling. The 32.00 GB/s memory bandwidth further constrains how quickly data can reach those shading units. No base or boost clock is listed, so the GPU’s actual operating frequency is not documented.

The practical implication is simple: this is not a high-throughput part. The theoretical figures point to a modest mobile GPU, but without benchmark entries the database does not support a leaderboard position or a percentage comparison to any named rival. Treat the 50th percentile as a database placement, not as evidence of a measured performance result.

Who Should Consider It

This GPU is an IGP, so it belongs in portable systems rather than in a discrete graphics card slot. The display outputs are portable device dependent, which means the host laptop determines what can be connected. A user who needs a built-in display solution for modest graphics work could consider it. The 2 GB GDDR5 frame buffer and 32.00 GB/s bandwidth are small and narrow enough that high-resolution texture sets will run into capacity and bandwidth limits quickly.

The 706.6 GFLOPS FP32 rate and 8 ROPs suggest a realistic operating envelope of lower detail settings and modest resolutions. The 384 shading units are too few for heavy shading workloads, and the 64-bit memory bus limits the data feeding those units. Users who expect high settings or high-resolution rendering should not look here; the data does not indicate that capability. For portable-device basic display output and light graphical acceleration, the Radeon 620 Mobile is positioned as a low-power integrated option, not a high-performance one.

Ray Tracing and Feature Set

The fact pack lists no RT cores and no tensor cores. Hardware-accelerated ray tracing and tensor-based acceleration are therefore not represented in the specification. The feature set is built around the conventional GCN 3.0 compute architecture, with 384 shading units, 24 TMUs, and 8 ROPs. FP16 output is 706.6 GFLOPS, identical to FP32, so there is no extra half-precision throughput.

API support includes DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. Software using these APIs can target the GPU, but DirectX 12 feature level 12_0 is the ceiling listed. The chip uses a 28 nm TSMC process with 1,550 million transistors on a 125 mm² die. The absence of RT core and tensor core counts is a clear specification signal: this is a rasterization-oriented part, with no dedicated ray tracing or tensor hardware in the data.

Power and Cooling

The AMD Radeon 620 Mobile has a TDP of 50 W. Slot width is listed as IGP, so it is not a discrete expansion card. Power connectors are listed as None, meaning the GPU does not require external power connectors; power is handled through the portable device’s integrated implementation. The suggested PSU field is null, so no power supply recommendation is provided by the data.

Because it is an IGP, there is no separate graphics card cooler to select. Cooling is tied to the host portable device. The 50 W figure defines the thermal envelope, but the actual solution is device-dependent. The PCIe 3.0 x8 bus interface is the connection path. Anyone looking for a standalone graphics card should not be looking at this part, since its form factor is an integrated GPU with no add-in-board dimensions listed.

Memory Subsystem

The memory configuration is a major performance limiter. The GPU comes with 2 GB of GDDR5, which is a small amount of memory for high-resolution assets. The bus width is 64 bit, a narrow interface, and the memory clock is 1000 MHz with 4 Gbps effective. Those figures combine to produce 32.00 GB/s of bandwidth. That bandwidth is the maximum rate at which textures and geometry can be moved into the 384 shading units.

The small capacity and narrow bus matter together. In high-resolution scenarios, 2 GB can be occupied quickly by textures, while 32.00 GB/s limits the speed of data transfer across the PCIe 3.0 x8-connected platform. The 8 ROPs and 7.360 GPixel/s pixel rate add another restriction on how much pixel data can be written per second. The 24 TMUs and 22.08 GTexel/s texture rate define the texture fetch side. Taken together, the memory subsystem is not built for high-bandwidth or high-capacity workloads; it is a low-power integrated configuration designed for modest graphical duties.
