AMD Radeon RX 6700 vs NVIDIA T550 Mobile Comparison

NVIDIA T550 Mobile and AMD Radeon RX 6700 represent two very different approaches to mobile graphics. The data shows a clear performance hierarchy, but the reasons behind it are where the analysis gets interesting. The T550 Mobile is a low-power professional part, while the RX 6700 is a high-performance consumer GPU. Their benchmark scores and specifications place them in different worlds, though both are now end-of-life products.

Where Each One Wins

The use-case split is stark. The NVIDIA T550 Mobile is engineered for a specific niche: low-power professional workloads. Its 23 W TDP and integrated form factor (IGP) make it suitable for compact, power-sensitive systems where basic GPU acceleration is needed. Its benchmark results, particularly the Geekbench OpenCL score of 35,521, show it handles compute tasks adequately for its class. The data indicates it sits at the 77th percentile of all GPUs, placing it slightly above average in the database’s recorded measurements.

The AMD Radeon RX 6700 wins decisively in raw performance. It records a Geekbench OpenCL score of 97,841, which is 63.7% higher than the T550 Mobile’s score. In Geekbench Vulkan, the RX 6700 scores 83,974 versus 30,801 for the T550 Mobile, a 63.3% lead. This GPU is built for demanding applications: gaming, content creation, and heavy compute. Its dual-slot design, 175 W TDP, and 450 W suggested PSU indicate it requires a substantial power delivery system. The RX 6700’s percentile ranking is 75, which is slightly lower than the T550 Mobile’s 77, despite having far higher absolute scores. This is because the RX 6700 competes in a higher performance tier where the database includes many faster desktop cards.

The T550 Mobile wins in efficiency and physical footprint. It uses no power connectors, fits in an IGP slot width, and draws only 23 W. This makes it a candidate for thin-and-light workstations or embedded designs. The RX 6700, by contrast, is a performance-first part. The benchmark results show it wins every head-to-head test, but the T550 Mobile’s advantage is in mobility and system integration, not speed.

Architecture Differences

The two GPUs come from different architectural generations and philosophies. The NVIDIA T550 Mobile uses the TU117 chip based on the Turing architecture, manufactured on a 12 nm process at TSMC. It packs 4,700 million transistors into a 200 mm² die, resulting in a transistor density of 23.5 million per mm². The RX 6700 uses the Navi 22 chip based on RDNA 2.0, built on a 7 nm process, also at TSMC. This die contains 17,200 million transistors across 335 mm², achieving a density of 51.3 million per mm². The 7 nm node allows AMD to pack nearly four times as many transistors into a larger, but still manageable, package.

The core configurations diverge significantly. The T550 Mobile has 1,024 shading units, 64 texture mapping units, and 32 ROPs. The RX 6700 has 2,304 shading units, 144 TMUs, and 64 ROPs. This means the RX 6700 has more than double the shading units and TMUs, and exactly double the ROPs. The RX 6700 also includes 36 ray tracing cores, a feature entirely absent from the T550 Mobile. Neither GPU has tensor cores listed in the database.

Memory architecture is another major divide. The T550 Mobile uses 4 GB of GDDR6 memory on a 64-bit bus, yielding 96.00 GB/s of bandwidth. The RX 6700 has 10 GB of GDDR6 on a 160-bit bus, providing 320.0 GB/s. This is a 3.33x difference in bandwidth, which directly impacts high-resolution textures and data-heavy workloads. Clock speeds also differ: the T550 Mobile has a base clock of 1065 MHz and a boost of 1665 MHz, while the RX 6700 starts at 1941 MHz and boosts to 2450 MHz, with a game clock of 2174 MHz. The memory speeds follow suit, with the RX 6700’s memory at 2000 MHz (16 Gbps effective) versus the T550 Mobile’s 1500 MHz (12 Gbps effective).

The API support also differs. The T550 Mobile supports DirectX 12 (12_1), while the RX 6700 supports DirectX 12 Ultimate (12_2). Both support OpenGL 4.6 and Vulkan 1.4. The RX 6700’s newer DirectX feature set enables advanced effects like ray tracing and variable rate shading at the API level. The T550 Mobile relies on older DirectX 12 features, which may limit its compatibility with the latest game engines.

The Verdict

The data clearly indicates the AMD Radeon RX 6700 is the superior performer for any task that demands graphical or compute power. It leads by over 60% in both recorded head-to-head benchmarks. Anyone needing high frame rates, large memory pools for textures, or ray tracing capabilities should choose the RX 6700. Its 10 GB memory and 320.0 GB/s bandwidth are essential for modern workloads, and its 36 ray tracing cores enable hardware-accelerated ray tracing.

The NVIDIA T550 Mobile serves a different purpose. Its 23 W TDP and IGP form factor make it the only viable choice for ultra-portable or passively cooled systems. The database shows it performs adequately for basic GPU tasks, but its 4 GB memory and 64-bit bus are severe limitations for serious work. It is a part for professional laptops where battery life and thermals trump performance. The T550 Mobile’s 77th percentile ranking, despite lower raw scores, reflects that it outperforms many older or lower-end GPUs in its power class.

The choice depends on the system design. If the requirement is maximum performance in a device with robust cooling and power delivery, the RX 6700 is the only option. If the requirement is minimal power draw and a compact footprint, the T550 Mobile is the appropriate pick. There is no scenario where the T550 Mobile outperforms the RX 6700 in measured benchmarks, but there are scenarios where the T550 Mobile’s power envelope is the deciding factor.

Head-to-Head Benchmarks

The two recorded head-to-head benchmarks both end with the same winner. In Geekbench OpenCL, the AMD Radeon RX 6700 scores 97,841 against the NVIDIA T550 Mobile’s 35,521. This represents a 63.7% delta in favor of AMD. The gap is enormous, indicating the RX 6700 handles compute workloads with far greater efficiency. The T550 Mobile’s 1,024 shading units and 3.410 TFLOPS FP32 are simply no match for the RX 6700’s 2,304 shading units and 11.29 TFLOPS.

In Geekbench Vulkan, the RX 6700 again dominates with a score of 83,974 versus 30,801. The delta is 63.3%, nearly identical to the OpenCL result. Vulkan is a low-level API that exposes the hardware more directly, so this close margin suggests the performance gap is consistent across different software stacks. The RX 6700’s 36 ray tracing cores and higher clock speeds likely contribute to its Vulkan advantage, as the API can utilize these features more efficiently.

The delta percentages are remarkably similar across both tests, which implies the performance difference is fundamental to the hardware design rather than workload-specific. The RX 6700’s 7 nm process, larger transistor count, and wider memory bus create a structural advantage that no driver or software optimization can overcome. The T550 Mobile’s scores, while lower, are not unimpressive for its power class. A 35,521 OpenCL score and 30,801 Vulkan score are respectable for a 23 W part, but they place it firmly in a different performance tier.

Specification Differences

The specification sheets reveal the full extent of the design divergence. The process nodes differ: 12 nm for NVIDIA versus 7 nm for AMD. This explains the transistor density gap, with the RX 6700 achieving 51.3M transistors per mm² versus 23.5M for the T550 Mobile. The die sizes are 200 mm² and 335 mm² respectively, with the RX 6700’s larger die containing substantially more hardware.

Memory is a critical differentiator. The T550 Mobile has 4 GB of GDDR6 on a 64-bit bus, while the RX 6700 has 10 GB on a 160-bit bus. Bandwidth figures are 96.00 GB/s versus 320.0 GB/s. The RX 6700’s memory clock is 2000 MHz (16 Gbps effective), compared to 1500 MHz (12 Gbps effective) for the T550 Mobile. These differences directly affect texture loading, frame buffer capacity, and compute data movement.

Compute units also vary widely. The T550 Mobile has 1,024 shading units, 64 TMUs, and 32 ROPs. The RX 6700 has 2,304 shading units, 144 TMUs, and 64 ROPs. Pixel rate is 53.28 GPixel/s for NVIDIA versus 156.8 GPixel/s for AMD. Texture rate is 106.6 GTexel/s versus 352.8 GTexel/s. FP32 throughput is 3.410 TFLOPS versus 11.29 TFLOPS, and FP16 is 6.820 TFLOPS versus 22.58 TFLOPS, both with a 2:1 ratio.

Power and physical specifications are opposites. The T550 Mobile has a 23 W TDP, IGP slot width, and no power connectors. The RX 6700 has a 175 W TDP, dual-slot width, and one 8-pin connector. The RX 6700’s dimensions are recorded as 267 mm length, 110 mm height, and 40 mm width. The T550 Mobile’s dimensions are not listed, but its IGP design implies a very small footprint. The bus interfaces also differ: PCIe 3.0 x16 for the T550 Mobile versus PCIe 4.0 x16 for the RX 6700. Display outputs are portable-device dependent for NVIDIA, while AMD lists 1x HDMI 2.1 and 3x DisplayPort 1.4a. The T550 Mobile has no release date recorded, but the RX 6700 launched on 2021-06-08. The T550 Mobile’s predecessor is Quadro Pascal-M and successor is Ampere-MW, while the RX 6700’s predecessor is Navi and successor is Navi III.
