AMD Radeon RX 7900 GRE vs NVIDIA T550 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive performance gap between these two GPUs. In the two shared tests—Geekbench OpenCL and Geekbench Vulkan—the AMD Radeon RX 7900 GRE wins both, and it does so by a wide margin. The Geekbench OpenCL result is particularly lopsided: the AMD card scores 175,758 against the NVIDIA T550 Mobile’s 35,521, which translates to a deltaPct of -79.8% from the AMD card’s perspective. In plain terms, the RX 7900 GRE delivers roughly five times the OpenCL compute throughput of the T550 Mobile.

The Vulkan result is similarly one-sided, though the gap narrows slightly. The RX 7900 GRE posts 99,850 in Geekbench Vulkan, while the T550 Mobile manages 30,801. That is a deltaPct of -69.2%, meaning the AMD part is more than three times faster in this API. Vulkan is often more efficient on modern architectures, yet the T550 Mobile’s Turing-based design cannot close the chasm created by the RX 7900 GRE’s raw resources.

It is worth remembering the T550 Mobile’s average benchmark score across all recorded tests is 33,161, which places it in the 77th percentile of all GPUs. The RX 7900 GRE’s average score is 32,456, also in the 77th percentile. This is a curious situation: despite being vastly faster in the head-to-head tests, the RX 7900 GRE’s average is slightly lower. This occurs because the AMD card’s benchmark suite includes additional tests like 3DMark Steel Nomad DX12 (4,814), Passmark DirectX 9 (310), and Passmark G3D (27,089), which pull its average down relative to the T550 Mobile’s more limited test set. The T550 Mobile has only two recorded benchmarks, both of which are relatively strong for its class.

Looking at the nearest rivals, the T550 Mobile sits within a tight cluster: its average score of 33,161 is essentially tied with the GeForce RTX 3050 Mobile (33,170, deltaPct 0%), slightly behind the Radeon Pro 570 (33,207, deltaPct -0.1%), and ahead of the P104-100 (32,982, deltaPct 0.5%) and T600 Mobile (32,849, deltaPct 1%). The RX 7900 GRE’s nearest rivals are older or lower-tier AMD FirePro and Radeon parts: the FirePro S10000 (32,388, deltaPct 0.2%), FirePro S9300 X2 (32,540, deltaPct -0.3%), RX 590 GME (32,601, deltaPct -0.4%), and Radeon Pro 570X (32,176, deltaPct 0.9%). These rivals are all within 1% of the RX 7900 GRE’s average, which underscores how misleading averages can be when the test suites differ.

Where Each One Wins

The RX 7900 GRE wins every benchmark where both cards are tested. In Geekbench OpenCL, its 175,758 score is not just a win—it is a category difference. This test stresses raw compute throughput, and the AMD card’s 5,120 shading units and 45.98 TFLOPS FP32 performance dwarf the T550 Mobile’s 1,024 shading units and 3.410 TFLOPS. The T550 Mobile’s 3.410 TFLOPS is a fraction of the AMD card’s output, and the benchmark reflects that.

In Geekbench Vulkan, the RX 7900 GRE’s 99,850 versus the T550 Mobile’s 30,801 shows that even when the workload is more graphics-oriented (Vulkan is a low-overhead graphics and compute API), the AMD card maintains a three-to-one lead. The T550 Mobile’s 32 ROPs and 64 TMUs are modest for a mobile workstation part, while the RX 7900 GRE’s 160 ROPs and 320 TMUs provide the pixel and texture throughput needed for higher-resolution rendering. The pixel rate difference is illustrative: the T550 Mobile produces 53.28 GPixel/s, while the RX 7900 GRE produces 359.2 GPixel/s—a 6.7x advantage. Texture rate is similarly skewed: 106.6 GTexel/s versus 718.4 GTexel/s.

For use-case splitting, the data supports a clear division. The T550 Mobile is a low-power, integrated form-factor (IGP) part designed for professional mobile workstations where battery life and thermal envelope matter more than raw speed. Its 23 W TDP and lack of power connectors make it suitable for thin-and-light laptops. The RX 7900 GRE, in contrast, is a dual-slot desktop card with a 260 W TDP, two 8-pin power connectors, and a suggested 600 W PSU. It is built for maximum performance in gaming and content creation, not for portability.

The T550 Mobile’s only potential advantage in the data is its efficiency per watt, though the FACT PACK does not provide direct efficiency ratios. Given its 23 W TDP versus 260 W, the T550 Mobile consumes roughly 11% of the power of the RX 7900 GRE while delivering about 20% of the OpenCL performance (35,521 / 175,758). That is not a favorable trade-off for the T550 Mobile, but for battery-powered devices, the absolute power draw is the more critical factor.

Specification Differences

The two cards differ in nearly every measurable specification. The T550 Mobile uses a 12 nm process node, while the RX 7900 GRE uses a 5 nm node. Both are fabricated by TSMC, but the transistor counts are vastly different: the T550 Mobile has 4,700 million transistors on a 200 mm² die (23.5M transistors per mm²), whereas the RX 7900 GRE has 57,700 million transistors on a 529 mm² die (109.1M per mm²). The RX 7900 GRE is not just bigger; it is also denser by a factor of roughly 4.6x.

Clock speeds differ as well. The T550 Mobile has a base clock of 1065 MHz and a boost clock of 1665 MHz. The RX 7900 GRE has a base clock of 1287 MHz, a game clock of 1880 MHz, and a boost clock of 2245 MHz. Memory clocks also differ: the T550 Mobile runs at 1500 MHz (12 Gbps effective), while the RX 7900 GRE runs at 2250 MHz (18 Gbps effective).

Memory capacity and bandwidth are starkly different. The T550 Mobile offers 4 GB of GDDR6 on a 64-bit bus, yielding 96.00 GB/s. The RX 7900 GRE offers 16 GB of GDDR6 on a 256-bit bus, yielding 576.0 GB/s—exactly six times the bandwidth. The compute metrics follow suit: FP32 performance is 3.410 TFLOPS for the T550 Mobile versus 45.98 TFLOPS for the RX 7900 GRE. FP16 performance is 6.820 TFLOPS versus 91.96 TFLOPS (both at 2:1 ratio). Pixel rate is 53.28 GPixel/s versus 359.2 GPixel/s, and texture rate is 106.6 GTexel/s versus 718.4 GTexel/s.

Physical and interface differences are equally pronounced. The T550 Mobile is an IGP (integrated graphics processor) with no length, height, or width dimensions listed, and its display outputs are "Portable Device Dependent." The RX 7900 GRE is a dual-slot card measuring 276 mm (10.9 inches) in length, 110 mm (4.3 inches) in height, and 51 mm (2 inches) in width, with outputs including 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C. The T550 Mobile uses PCIe 3.0 x16, while the RX 7900 GRE uses PCIe 4.0 x16.

Architecture Differences

The architectural divide is generational. The NVIDIA T550 Mobile is based on the TU117 chip, using the Turing architecture, and belongs to the Quadro Turing-M (Tx000) generation. Its predecessor is Quadro Pascal-M, and its successor is Ampere-MW. It lacks dedicated ray tracing cores and tensor cores—the FACT PACK lists both as null. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.

The AMD Radeon RX 7900 GRE is based on the Navi 31 chip, using the RDNA 3.0 architecture, with the codename "Plum Bonito." It belongs to the Navi III (RX 7000) generation, with predecessor Navi II and successor Navi IV. Critically, it includes 80 ray tracing cores, a feature entirely absent from the T550 Mobile. It supports DirectX 12 Ultimate (12_2), which is a higher feature level than the T550 Mobile’s 12_1, along with OpenGL 4.6 and Vulkan 1.4.

The process node difference is significant: 12 nm for Turing versus 5 nm for RDNA 3.0. This explains the transistor density gap—the RX 7900 GRE packs 109.1M transistors per mm² versus 23.5M for the T550 Mobile. The RX 7900 GRE also has a game clock (1880 MHz), which the T550 Mobile lacks, indicating AMD’s dual clock structure for gaming workloads. The T550 Mobile has no such gaming-specific clock.

The RX 7900 GRE’s 80 ray tracing cores provide hardware acceleration for ray-traced workloads, a capability the T550 Mobile cannot offer. This is a functional difference, not just a numerical one: games and applications that use ray tracing will either run poorly or fall back to software on the T550 Mobile. The T550 Mobile’s lack of tensor cores also means no hardware-accelerated AI inference, which is becoming increasingly relevant in professional workloads.

The Verdict

The data points to an unambiguous conclusion: the AMD Radeon RX 7900 GRE is the superior performer in every benchmark where the two are compared. It wins both head-to-head tests, offers 16 GB of memory versus 4 GB, has six times the memory bandwidth, and provides nearly 13.5 times the FP32 compute throughput (45.98 TFLOPS versus 3.410 TFLOPS). It also includes 80 ray tracing cores, a feature the T550 Mobile entirely lacks.

However, the choice is not simply about performance. The T550 Mobile is an IGP with a 23 W TDP, no power connectors, and portable-device-dependent outputs. It is designed for mobile workstations where power draw and physical space are constrained. The RX 7900 GRE is a 260 W dual-slot desktop card requiring a 600 W PSU and two 8-pin connectors. It cannot be used in a laptop, and its physical dimensions (276 mm length) demand a full-size desktop chassis.

Who should pick the T550 Mobile? A user who needs a professional-grade GPU in a thin-and-light laptop, who prioritizes battery life and low heat over raw performance, and who does not require ray tracing or high-end gaming. Its 77th percentile standing among all GPUs is respectable for an IGP, and its nearest rivals (RTX 3050 Mobile, Radeon Pro 570) are similarly low-power parts.

Who should pick the RX 7900 GRE? A desktop user who demands maximum performance for gaming, content creation, or compute workloads, and who has the power supply and case space to accommodate it. Its 77th percentile ranking, despite being dragged down by less relevant Passmark tests, understates its true capability in modern workloads like 3DMark Steel Nomad DX12 (4,814) and Geekbench OpenCL (175,758). The 16 GB memory buffer and 576.0 GB/s bandwidth make it suitable for high-resolution textures and large datasets. The launch MSRP was 549 USD, which the data shows as a single point of reference.

In summary, the RX 7900 GRE is the clear performance winner, but the T550 Mobile serves a fundamentally different purpose. The benchmark data cannot reconcile these two use cases—it can only show that if raw speed is the goal, the AMD card is the only choice.
