GPU Comparison

Head-to-Head Benchmarks

The benchmark data shows two very different performers, with each card taking one decisive victory. The AMD Radeon Pro 575X wins the Geekbench Vulkan test by a commanding 25.5% margin, scoring 37,919 against the NVIDIA T600 Mobile's 30,211. That is not a marginal gap; it is a dominant result that positions the AMD part far ahead in Vulkan workloads. The NVIDIA T600 Mobile counters in Geekbench OpenCL, scoring 35,486 versus 34,773, a 2% edge that is slim but consistent with its higher real-world compute throughput in that API.

Looking at the broader database picture, the AMD Radeon Pro 575X holds a substantial lead in average benchmark score, 39,116 versus 32,849 for the NVIDIA T600 Mobile. That is roughly a 19% advantage in aggregate performance. The AMD part also ranks in the 82nd percentile of all GPUs in the database, while the NVIDIA part sits in the 77th percentile. In direct head-to-head terms, each card claims one win, but the magnitude of the AMD Vulkan victory far outweighs the narrow NVIDIA OpenCL win.

The nearest rivals for the AMD Radeon Pro 575X illustrate how tightly grouped it is at the top of its class. It sits 1.1% above the AMD Radeon Pro 580X and the NVIDIA GeForce MX570 A, and it trails the AMD Radeon Pro 575 and NVIDIA RTX A500 Mobile by 1.1% each. These deltas are small enough that day-to-day variance in workloads could flip the order. For the NVIDIA T600 Mobile, the surrounding field is similarly close: it is 0.4% below the NVIDIA P104-100, 0.8% above the AMD Radeon RX 590 GME, 0.9% above the AMD FirePro S9300 X2, and 0.9% below the NVIDIA T550 Mobile. The T600 Mobile's competition is a full tier lower in average score, which reinforces that the AMD part competes at a higher performance level.

The Geekbench OpenCL result deserves nuance. The NVIDIA T600 Mobile wins by only 2%, and the AMD card's OpenCL score of 34,773 is close to its own Vulkan score of 37,919. The NVIDIA part, by contrast, drops sharply from 35,486 in OpenCL to 30,211 in Vulkan, a 14.9% decline. This suggests the NVIDIA card is less consistent across APIs, while the AMD part maintains a more uniform performance profile.

Where Each One Wins

The AMD Radeon Pro 575X is the clear choice for Vulkan-based workloads. Its 25.5% lead in Geekbench Vulkan indicates a substantial advantage in applications that leverage that API, which includes many modern game engines and cross-platform compute frameworks. The data shows the AMD part also wins on raw aggregate performance, with an average benchmark score of 39,116 versus 32,849, so for users running a mix of APIs, the AMD card will generally come out ahead.

The NVIDIA T600 Mobile wins the OpenCL comparison, but only by 2%. In applications that are specifically optimized for OpenCL, the NVIDIA card holds a slight edge. However, this win is narrow enough that it may not translate into a perceptible real-world difference in most OpenCL tasks. The NVIDIA card also has a much lower power envelope, which is discussed later, and that may be the more meaningful advantage in thermally constrained mobile systems.

For users who prioritize consistent performance across different graphics and compute APIs, the AMD part is the safer bet. For users who know their workload is OpenCL-bound and runs on NVIDIA hardware, the T600 Mobile will perform adequately, but the margin is thin. The AMD card's higher percentile ranking, 82nd versus 77th, and its higher average score both point to it being the stronger all-around performer in this pairing.

Architecture Differences

The AMD Radeon Pro 575X uses the Ellesmere chip built on GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. It packs 5,700 million transistors into a 232 mm² die, yielding a transistor density of 24.6 million per square millimeter. The NVIDIA T600 Mobile uses the TU117 chip based on Turing architecture, manufactured on a 12 nm process at TSMC. It contains 4,700 million transistors on a 200 mm² die, with a transistor density of 23.5 million per square millimeter. The AMD chip is physically larger and denser, but the NVIDIA chip uses a more advanced process node.

The compute resources differ sharply. The AMD card has 2,048 shading units, 128 texture mapping units, and 32 raster operation units. The NVIDIA card has 896 shading units, 56 TMUs, and 32 ROPs. The AMD part has more than double the shading units and TMUs, which explains its higher texture rate of 140.3 GTexel/s versus 78.96 GTexel/s. The two cards match on ROPs at 32, but the NVIDIA card achieves a higher pixel rate of 45.12 GPixel/s versus 35.07 GPixel/s, likely due to its higher boost clock.

FP32 compute also favors the AMD card substantially. The AMD Radeon Pro 575X delivers 4.489 TFLOPS of FP32, while the NVIDIA T600 Mobile delivers 2.527 TFLOPS. That is a 77.6% advantage for the AMD part. In FP16, the situation flips in a specific way: the AMD card delivers 4.489 TFLOPS at a 1:1 ratio, meaning no FP16 acceleration, while the NVIDIA card delivers 5.053 TFLOPS at a 2:1 ratio, meaning it can process two FP16 operations per clock per shader. For workloads that use FP16 heavily, the NVIDIA card is faster, but for general FP32 compute, the AMD card dominates.

The API support also differs. The AMD card supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The NVIDIA card supports DirectX 12 (12_1, a higher feature level that adds features like conservative rasterization among other features, though neither card has RT cores or tensor cores, as neither has RT cores listed), OpenGL 4.6, and Vulkan 1.4. The higher DirectX feature level on the NVIDIA part may matter for certain DX12 feature-level-dependent applications. The NVIDIA card also supports a newer Vulkan version, 1.4 versus 1.3, which could matter for current-generation Vulkan extensions, though the benchmark results do not reflect that in performance.

Specification Differences

The two cards differ in several key specifications. The process node differs: 14 nm for AMD versus 12 nm for NVIDIA. The transistor count differs: 5,700 million versus 4,700 million, and die size differs: 232 mm² versus 200 mm². The AMD card has a higher transistor density at 24.6 million per mm² versus 23.5 million per mm².

Clock behavior differs. The AMD card has no listed base or boost clock, while the NVIDIA card has a base clock of 780 MHz and a boost clock of 1,410 MHz. Memory clocks also differ: the AMD card runs its memory at 1,695 MHz with 6.8 Gbps effective, while the NVIDIA card runs at 1,500 MHz with 12 Gbps effective. Despite the lower memory clock, the NVIDIA card's GDDR6 memory achieves a higher effective data rate, but the AMD card has a wider 256-bit bus versus 128-bit, resulting in higher bandwidth: 217.0 GB/s versus 192.0 GB/s.

Memory type differs as well: GDDR5 on the AMD card versus GDDR6 on the NVIDIA card. Both have 4 GB of memory, but the bus width difference is significant. The AMD card has far more shading units (2,048 versus 896), TMUs (128 versus 56), and equal ROPs (32). The pixel rate favors NVIDIA at 45.12 GPixel/s versus 35.07 GPixel/s, while the texture rate heavily favors AMD at 140.3 GTexel/s versus 78.96 GTexel/s.

Power consumption is a major differentiator. The AMD Radeon Pro 575X has a TDP of 150 W, while the NVIDIA T600 Mobile has a TDP of 40 W. Both are IGP slot width, both have no power connectors, and both are portable-device-dependent on display outputs. Both use PCIe 3.0 x16.

Release dates also differ, with the AMD card released on March 2019, and the NVIDIA card released April 2021, a gap of about two years. The NVIDIA card has predecessors (Quadro Pascal-M) and successors (Ampere-MW) listed in the database, while the AMD card has none listed. The AMD card is end-of-life, and the NVIDIA card is also end-of-life.

The Verdict

The data points to the AMD Radeon Pro 575X as the stronger performer overall. It holds a 25.5% lead in Vulkan, a 19% lead in average benchmark score, and a higher percentile ranking (82nd versus 77th). Its FP32 compute advantage and higher texture rate make it the better choice for general-purpose compute and graphics workloads that run through Vulkan or a mix of APIs.

The NVIDIA T600 Mobile is the better choice only in specific scenarios: OpenCL-bound workloads where its 2% edge matters, FP16-heavy applications where its 5.053 TFLOPS at a 2:1 ratio beats the AMD card's 1:1 FP16 performance, and systems where the 40 W TDP is a hard constraint versus the AMD card's 150 W. The NVIDIA card also supports a higher DirectX feature level (12_1 versus 12_0) and a newer Vulkan version (1.4 versus 1.3), which could matter for certain feature-dependent applications.

For most users, the AMD Radeon Pro 575X is the recommended pick. Its aggregate performance is in a different class, and its Vulkan dominance is decisive. The NVIDIA T600 Mobile is a lower-power alternative that trades significant compute throughput for efficiency. If the workload is known to be OpenCL-heavy and power is a limiting factor, the NVIDIA card earns its place. Otherwise, the AMD card's higher scores, higher percentile, and broader API consistency make it the stronger choice in this comparison.
