AMD Radeon RX 7800M vs NVIDIA T600 Mobile Comparison

Head-to-Head Benchmarks

The recorded data leaves no ambiguity: the AMD Radeon RX 7800M dominates the NVIDIA T600 Mobile in every head-to-head benchmark where both were measured. Across two shared tests, the RX 7800M claims 2 wins against 0 for the T600 Mobile.

The first comparison, Geekbench OpenCL, shows the AMD part scoring 120,778 points against the NVIDIA part’s 35,486 points. That represents a delta of -70.6% from the perspective of the T600 Mobile, meaning the NVIDIA GPU trails by roughly 70.6% of the AMD score. In practical terms, the RX 7800M delivers more than 3.4 times the raw compute throughput in this API, a margin that makes the T600 Mobile’s OpenCL result look like a low-power entry point rather than a serious workstation contender.

The second shared test, Geekbench Vulkan, widens the gap even further. The RX 7800M posts 126,668 points, while the T600 Mobile manages 30,211 points. The delta here is -76.1% for the NVIDIA part, which is a larger relative deficit than in OpenCL. This suggests the AMD architecture scales better with Vulkan’s low-level abstraction, extracting more of its theoretical hardware capability under that API. The T600 Mobile’s Vulkan score is less than a quarter of the AMD result, a stark contrast when placed side by side.

Looking at the broader benchmark picture, the RX 7800M also brings a much wider test portfolio. Beyond the two Geekbench entries, the AMD part has recorded Passmark scores across DirectX 9, 10, 11, 12, G2D, G3D, and GPU compute, plus a 3DMark Steel Nomad DX12 result. The T600 Mobile has only the two Geekbench entries in its profile, so the database contains no direct comparison for those additional workloads. However, the RX 7800M’s Passmark G3D score of 17,613 and its GPU compute score of 9,342 indicate a graphics part that is not merely compute-heavy but also well-rounded in rasterization and general 2D performance, with a G2D score of 892.

The average benchmark scores reinforce the same conclusion. The RX 7800M’s average across all recorded tests is 27,883, while the T600 Mobile’s average is 32,849. On first glance, the NVIDIA part seems higher, but this is misleading because the averages are computed over different test sets. The T600 Mobile’s average is pulled up by its two Geekbench scores, which are its only data points. The RX 7800M’s average is dragged down by its Passmark DirectX results, which use a different scoring scale entirely (scores in the 89 to 176 range for API-specific tests). When the two parts share the same test, the Geekbench results, the AMD card wins by a massive margin. The percentile ranking versus all GPUs tells a similar story: the T600 Mobile sits at the 77th percentile, slightly above the RX 7800M’s 73rd percentile, but again this is a function of the different test suites rather than a head-to-head verdict.

Architecture Differences

The two GPUs come from different eras and design philosophies, and the data shows a generational leap in almost every physical and architectural dimension.

The NVIDIA T600 Mobile is built on the Turing architecture, using the TU117 chip, fabricated on a 12 nm process at TSMC. It packs 4,700 million transistors into a 200 mm² die, giving a transistor density of 23.5 million per square millimeter. Its generation is listed as Quadro Turing-M (Tx000), and it is marked as end-of-life, with a release date of April 11, 2021. The chip’s predecessor is Quadro Pascal-M and its successor is Ampere-MW, placing it squarely in the professional mobile GPU line.

The AMD Radeon RX 7800M, by contrast, uses the RDNA 3.0 architecture with the Navi 32 chip, codenamed Wheat Nas. It is fabricated on a 5 nm process, also at TSMC, and crams 28,100 million transistors into a 346 mm² die. That equates to a transistor density of 81.2 million per square millimeter, which is roughly 3.5 times the density of the NVIDIA chip. The RX 7800M belongs to the Radeon RX 7000 series and the Navi Mobile (RX 7000M) generation, with a release date of September 10, 2024. Its predecessor is listed as Polaris Mobile, and it has no successor recorded, indicating it is still an active product in the database.

Clock speeds also tell a story of higher power limits and more aggressive boosting. The T600 Mobile runs at a base clock of 780 MHz with a boost of 1410 MHz. The RX 7800M starts at 1295 MHz base, boosts to 2335 MHz, and has a game clock of 2145 MHz. The memory clocks differ as well: the NVIDIA part uses 1500 MHz with 12 Gbps effective data rate, while the AMD part runs at 2250 MHz with 18 Gbps effective. The RX 7800M’s memory subsystem is wider and faster, with a 192-bit bus versus 128-bit, and a bandwidth of 432.0 GB/s versus 192.0 GB/s.

Shader resources are vastly different. The T600 Mobile has 896 shading units, 56 texture mapping units, and 32 ROPs. The RX 7800M has 3,840 shading units, 240 TMUs, and 96 ROPs. The AMD part also includes 60 ray tracing cores, while the NVIDIA part has none listed. Neither part lists tensor cores, which is notable for the Turing chip since it typically includes them, but the database records no such field for the T600 Mobile. Compute throughput follows the resource counts: the RX 7800M delivers 35.87 TFLOPS FP32 and the same 35.87 TFLOPS FP16 (1:1 ratio), while the T600 Mobile manages 2.527 TFLOPS FP32 and 5.053 TFLOPS FP16 (2:1 ratio). Pixel and texture rates are equally lopsided: 224.2 GPixel/s and 560.4 GTexel/s for AMD versus 45.12 GPixel/s and 78.96 GTexel/s for NVIDIA.

Power and connectivity also differ sharply. The T600 Mobile has a TDP of 40 W and requires no power connectors, fitting the IGP slot width with a PCIe 3.0 x16 interface. The RX 7800M has a TDP of 180 W, also with no power connectors and the same IGP slot width, but it uses PCIe 4.0 x16. API support shows the RX 7800M with DirectX 12 Ultimate (12_2), while the T600 Mobile is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Where Each One Wins

Given the head-to-head data, the RX 7800M wins everywhere the two parts overlap. In Geekbench OpenCL and Vulkan, the AMD card is the clear victor with margins of 70.6% and 76.1% respectively. For any workload that leverages compute APIs or modern graphics APIs, the RX 7800M is the stronger choice by a wide margin.

The T600 Mobile’s only advantage lies in its power envelope and its specific positioning. At 40 W TDP, it is a low-power, integrated-class mobile GPU that fits into slim laptops without external power connectors. Its 4 GB GDDR6 memory on a 128-bit bus is modest but sufficient for light professional tasks. Its percentile rank of 77 versus the RX 7800M’s 73 suggests that, within its own benchmark set, the T600 Mobile performs respectably relative to all GPUs in the database, but that set is limited to two tests.

For gaming, the RX 7800M’s 3DMark Steel Nomad DX12 score of 2,994 and its Passmark G3D score of 17,613 indicate strong rasterization capability, backed by 12 GB of VRAM on a 192-bit bus. The T600 Mobile has no recorded gaming benchmark, so the database cannot confirm its gaming performance, but its compute numbers suggest it is not designed for that purpose. For workstation compute, the RX 7800M’s FP32 throughput of 35.87 TFLOPS is an order of magnitude higher than the T600 Mobile’s 2.527 TFLOPS, making it suitable for simulation, rendering, and machine learning inference workloads. The T600 Mobile’s FP16 capability at 5.053 TFLOPS (2:1) is also far below the RX 7800M’s FP16 at 35.87 TFLOPS (1:1), so even mixed-precision workloads lean heavily toward AMD.

The T600 Mobile’s real strength is efficiency per watt, but the database does not provide a per-watt score, so any claim must be qualitative. Its 40 W TDP is 140 W lower than the RX 7800M’s 180 W, and that difference is the only numeric basis for choosing the NVIDIA part: systems with strict thermal or battery constraints.

The Verdict

The database’s head-to-head results are decisive: the AMD Radeon RX 7800M outperforms the NVIDIA T600 Mobile in both shared benchmarks, with margins of 70.6% in OpenCL and 76.1% in Vulkan. Anyone selecting a GPU for compute-heavy tasks, modern DirectX 12 Ultimate workloads, or high-resolution graphics should pick the RX 7800M. Its 12 GB memory, 432.0 GB/s bandwidth, 60 ray tracing cores, and 35.87 TFLOPS FP32 throughput place it in a different performance class entirely.

The NVIDIA T600 Mobile is only preferable in scenarios where its 40 W TDP is a hard constraint. Systems that cannot accommodate a 180 W GPU, such as ultra-thin laptops or passively cooled designs, have no choice but to consider the T600 Mobile. Its 4 GB memory and 2.527 TFLOPS FP32 are sufficient for basic professional graphics or light compute, and its end-of-life status means it is a legacy option. The RX 7800M is active, newer, and faster in every measured dimension, making it the clear recommendation for any user who can supply the power budget. For everyone else, the data says the RX 7800M is the only rational choice.
