AMD Radeon Vega 6: Tests and Gaming Performance

AMD Radeon Vega 6 is integrated graphics for Ryzen processors from several generations. It operates at different frequencies and with different power limits in different APUs, so performance depends on the specific processor and memory.

Vega 6 has no dedicated video memory. It uses the system’s RAM-DDR4 or LPDDR4X. Dual-channel mode and memory bandwidth have a noticeable effect on FPS and benchmark results.

Vega 6 in Different Devices

Vega 6 includes 6 CUs and 384 stream processors based on the Vega architecture. This graphics solution appears in both mobile Ryzen processors and desktop APUs.

The differences between systems are shown by 3DMark Time Spy Graphics:

Device Processor Vega 6 Frequency Time Spy Graphics
Beelink SER5 Ryzen 5 5560U up to 1600 MHz 981
Lenovo IdeaPad 3 15ALC6 Ryzen 3 5300U up to 1500 MHz 885
Lenovo IdeaPad S540-13ARE Ryzen 5 4600U up to 1500 MHz 852
Xiaomi RedmiBook 16 R5 Ryzen 5 4500U up to 1500 MHz 783
HP ProBook x360 435 G7 Ryzen 5 4500U up to 1500 MHz 685

Even laptops with the same Ryzen 5 4500U produce different results. The Xiaomi RedmiBook 16 scores 783 points, while the HP ProBook x360 435 G7 scores 685. That is a difference of about 14% with the same processor and graphics core.

Therefore, Vega 6 results are best reported together with the processor and device model. The iGPU name alone is not enough to accurately assess its performance.

Vega 6 in the Ryzen 3 5300G

In the Ryzen 3 5300G, Vega 6 operates at up to 1700 MHz and has a higher power limit than the mobile versions.

With a single memory module, bandwidth is lower, which limits Vega 6 performance. For a desktop system with the Ryzen 3 5300G, two DDR4 modules in dual-channel mode are preferable.

At 1920x1080, the Ryzen 3 5300G produces the following results:

Game Average FPS
Counter-Strike: Global Offensive, Medium 89 FPS
Rainbow Six Siege 52 FPS
F1 2020 46 FPS
Doom Eternal 40 FPS
Shadow of the Tomb Raider 28 FPS
Assassin's Creed Valhalla, Lowest 26 FPS
Watch Dogs: Legion 23 FPS

In less demanding games, Vega 6 maintains more than 50 FPS, while demanding titles drop to 20-30 FPS. In such games, settings-and sometimes the resolution-have to be lowered.

How Memory Affects Vega 6

Vega 6 uses system RAM as video memory. Therefore, a system with two DDR4 modules is usually faster than an otherwise identical system with a single memory stick.

In laptops, power and cooling limitations also affect performance, so the same Ryzen 5 4500U can perform differently in different models.

Conclusion

AMD Radeon Vega 6 is designed for office tasks, video, older games, and undemanding competitive titles. In more demanding games, graphics quality has to be lowered, and sometimes the resolution must be reduced below 1080p.

The same Vega 6 name does not mean identical performance. Differences in the processor, GPU frequency, memory, and power limits lead to different FPS and 3DMark results even with the same 6 CUs.

Texture Mapping Units (TMUs) serve as components of the GPU, which are capable of rotating, scaling, and distorting binary images, and then placing them as textures onto any plane of a given 3D model. This process is called texture mapping.

Memory Bus
?
The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth
?
Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

Pixel Rate
?
Pixel fill rate refers to the number of pixels a graphics processing unit (GPU) can render per second, measured in MPixels/s (million pixels per second) or GPixels/s (billion pixels per second). It is the most commonly used metric to evaluate the pixel processing performance of a graphics card.

FP16 (half)
?
An important metric for measuring GPU performance is floating-point computing capability. Half-precision floating-point numbers (16-bit) are used for applications like machine learning, where lower precision is acceptable. Single-precision floating-point numbers (32-bit) are used for common multimedia and graphics processing tasks, while double-precision floating-point numbers (64-bit) are required for scientific computing that demands a wide numeric range and high accuracy.
