AMD Radeon RX Vega 56 vs NVIDIA T600 Mobile Comparison

The Verdict

The benchmark data presents a clear performance hierarchy between these two very different graphics solutions. The AMD Radeon RX Vega 56 achieves an average benchmark score of 37,507, which places it in the 81st percentile of all GPUs in the database. The NVIDIA T600 Mobile, by contrast, records an average benchmark score of 32,849, placing it in the 77th percentile. This is a substantial gap of roughly 14% in average score, indicating that the RX Vega 56 is the significantly faster part for compute and graphics workloads.

However, the correct choice depends heavily on context. The RX Vega 56 is a dual-slot, 280 mm long card requiring two 8-pin power connectors and a 550 W power supply, drawing 210 W. It is intended for desktop systems with generous space and power budgets. The T600 Mobile is an IGP (integrated graphics processor) solution with a 40 W power draw, no power connectors, and dimensions that are defined as "Portable Device Dependent," making it suitable for compact or mobile platforms where power efficiency is the primary constraint. The data shows that the RX Vega 56 is the straightforward pick for raw performance and is suitable for desktop users with adequate cooling and PSU support. The T600 Mobile is the pick for portable or space-constrained systems where the 40 W thermal envelope is non-negotiable.

Architecture Differences

The two GPUs come from entirely different design philosophies and eras. The AMD Radeon RX Vega 56 is built on the GCN 5.0 architecture, codenamed Vega 10, released in 2017. It is manufactured on a 14 nm process by GlobalFoundries, integrating 12,500 million transistors on a 495 mm² die, resulting in a transistor density of 25.3 million per mm². The NVIDIA T600 Mobile is a Turing architecture part, codenamed TU117, released in 2021. It uses TSMC's 12 nm process, with 4,700 million transistors on a 200 mm² die, which yields a density of 23.5 million per mm².

The compute resources differ dramatically. The RX Vega 56 has 3,584 shading units, 224 texture mapping units (TMUs), and 64 render output units (ROPs). The T600 Mobile has 896 shading units, 56 TMUs, and 32 ROPs. The AMD part has four times the shader count and TMUs, and double the ROPs. Consequently, the pixel rate for the AMD card is 94.14 GPixel/s compared to 45.12 GPixel/s for the T600, and the texture rate is 329.5 GTexel/s versus 78.96 GTexel/s. The FP32 compute throughput is 10.54 TFLOPS for the AMD card versus 2.527 TFLOPS for the NVIDIA. Both support FP16 operations at a 2:1 ratio, with the RX Vega 56 reaching 21.09 TFLOPS and the T600 Mobile reaching 5.053 TFLOPS.

Memory configuration is also a major differentiator. The RX Vega 56 features 8 GB of HBM2 memory on a 2048-bit bus, delivering 409.6 GB/s of bandwidth. The T600 Mobile has 4 GB of GDDR6 memory on a 128-bit bus, providing 192.0 GB/s. The AMD card has double the capacity and more than double the bandwidth. Clock speeds differ, with the AMD base clock at 1156 MHz and boost at 1471 MHz, while the T600 Mobile runs at a 780 MHz base and 1410 MHz boost. The AMD card is a PCIe 3.0 x16 device, as is the NVIDIA part. Display outputs are 1x HDMI 2.0b and 3x DisplayPort 1.4a for the AMD card, while the T600 Mobile's outputs are portable device dependent. The AMD part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The T600 Mobile supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The database does not include direct head-to-head benchmark results between these two specific cards. Instead, the analysis relies on the aggregated average benchmark score and the individual test results for each card. The RX Vega 56 records a score of 1,501 in the 3DMark Steel Nomad DX12 test and a Geekbench Metal score of 73,512. The T600 Mobile records a Geekbench OpenCL score of 35,486 and a Geekbench Vulkan score of 30,211. The average score for the RX Vega 56 is 37,507, and the average for the T600 Mobile is 32,849, showing a clear relative performance lead for the AMD part.

Looking at the nearest rivals listed in the database provides context. The RX Vega 56 sits very close to the NVIDIA Tesla P4, which is 0.3% faster. It is also within 0.4% of the NVIDIA GeForce RTX 4070, and 1.6% below the NVIDIA GeForce RTX 4080 Mobile. This places the RX Vega 56 in a competitive segment near modern desktop and mobile high-end parts, despite its older architecture. The T600 Mobile, on the other hand, is closest to the NVIDIA P104-100, which is 0.4% faster. It is 0.8% faster than the AMD Radeon RX 590 GME, 0.9% faster than the AMD FirePro S9300 X2, and 0.9% slower than the NVIDIA T550 Mobile. This shows the T600 Mobile sits in a lower performance tier, closer to mid-range desktop or entry-level mobile parts.

When comparing the two directly, the RX Vega 56 is 14.2% faster in average score than the T600 Mobile. The delta is consistent with the massive differences in shader count, memory bandwidth, and power envelope. The RX Vega 56 is clearly the more powerful part in raw compute and graphics throughput. The T600 Mobile, however, achieves its scores at a fraction of the power draw, showing a different engineering priority.
