AMD Radeon RX 7650 GRE vs NVIDIA GeForce RTX 4050 Mobile Comparison

The AMD Radeon RX 7650 GRE and NVIDIA GeForce RTX 4050 Mobile represent two distinctly different design goals within the same performance conversation. The RX 7650 GRE is a desktop-oriented card built around a larger chip with higher power limits, while the RTX 4050 Mobile is a laptop-part engineered for efficiency and compact integration. The database records one head-to-head benchmark between them, with the AMD part winning that contest, but the full specification sheets reveal why each product exists and who should consider it.

The Verdict

The recorded data points to a clear performance hierarchy. In the single shared benchmark, Geekbench OpenCL, the AMD Radeon RX 7650 GRE scores 83109 against the NVIDIA GeForce RTX 4050 Mobile’s 74748, a delta of 11.2 percent in AMD’s favor. The average benchmark score across all recorded tests further separates them: the RX 7650 GRE averages 42723, while the RTX 4050 Mobile averages 19049. That difference is substantial, roughly 124 percent higher for the AMD card.

However, the two products are not competing for the same chassis. The RX 7650 GRE carries a 170 W TDP, uses a dual-slot cooler, and requires a 450 W power supply, making it a desktop-only solution. The RTX 4050 Mobile has a 50 W TDP, is listed as an IGP (integrated graphics package), and draws power from the portable device it is installed in. Buyers who need a fixed desktop build with maximum raw compute from these two options should select the RX 7650 GRE. Those who require a laptop solution, where power draw and physical space are constrained, have only the RTX 4050 Mobile as the viable choice. The data does not support any scenario where the RTX 4050 Mobile outperforms the RX 7650 GRE in compute workloads, but the mobile part’s entire purpose is efficiency within a portable platform.

The percentile rankings reinforce this split. The RX 7650 GRE sits at the 83rd percentile against all GPUs in the database, while the RTX 4050 Mobile sits at the 63rd percentile. The AMD part is positioned among much stronger hardware, with its nearest rivals including the NVIDIA GeForce RTX 4070 SUPER (average score 43223, delta -1.2 percent) and the NVIDIA GeForce RTX 5050 Mobile (average score 43268, delta -1.3 percent). The RTX 4050 Mobile’s nearest rivals are older or lower-tier parts like the AMD Radeon RX 6600 (average score 19036, delta 0.1 percent) and the NVIDIA Quadro K6000 (average score 19030, delta 0.1 percent). The data shows the RX 7650 GRE competes in a higher performance class entirely.

Where Each One Wins

The RX 7650 GRE wins on raw compute across the board. Its 22.08 TFLOPS FP32 performance dwarfs the RTX 4050 Mobile’s 8.986 TFLOPS, a ratio of roughly 2.46 to 1. Texture rate follows the same pattern: 345.0 GTexel/s versus 140.4 GTexel/s. Pixel rate is also higher on the AMD card at 172.5 GPixel/s versus 84.24 GPixel/s. Memory bandwidth favors AMD as well, with 288.0 GB/s against 192.0 GB/s, though the RTX 4050 Mobile’s smaller memory bus and lower capacity are expected for its form factor.

The RTX 4050 Mobile wins on power efficiency and portability. At 50 W, its TDP is less than one-third of the RX 7650 GRE’s 170 W. It requires no external power connectors, while the AMD card needs a single 8-pin connector. The NVIDIA part’s dimensions are not listed, but its IGP slot width indicates it is designed to be soldered or mounted directly onto a laptop motherboard. The RX 7650 GRE measures 204 mm in length and 115 mm in height, which is incompatible with any compact mobile chassis. The RTX 4050 Mobile also has a higher transistor density at 118.9 million transistors per square millimeter versus 65.2 million for the AMD part, reflecting its newer 5 nm process node versus the AMD card’s 6 nm node.

The NVIDIA part also brings 80 tensor cores and 20 RT cores, whereas the RX 7650 GRE has no tensor cores and 32 RT cores. The RTX 4050 Mobile has more shading units (2560 versus 2048) but fewer texture mapping units (80 versus 128) and fewer ROPs (48 versus 64). In workloads that rely heavily on tensor operations, such as certain AI inference tasks, the RTX 4050 Mobile’s dedicated tensor hardware may provide an advantage, though the database does not record any benchmark that isolates this capability.

Architecture Differences

The RX 7650 GRE uses the Navi 33 chip built on RDNA 3.0 architecture, manufactured on a 6 nm process at TSMC. The chip contains 13,300 million transistors on a 204 mm² die. The RTX 4050 Mobile uses the AD107 chip built on Ada Lovelace architecture, manufactured on a 5 nm process also at TSMC. The NVIDIA chip contains 18,900 million transistors on a smaller 159 mm² die. This means the NVIDIA part packs more transistors into less silicon, achieving a transistor density of 118.9 million per square millimeter, nearly double the AMD part’s 65.2 million.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level compatibility is identical. The memory configurations differ fundamentally: the RX 7650 GRE has 8 GB of GDDR6 on a 128-bit bus, while the RTX 4050 Mobile has 6 GB of GDDR6 on a 96-bit bus. The AMD card’s memory clock is 2250 MHz with 18 Gbps effective data rate, while the NVIDIA part runs at 2000 MHz with 16 Gbps effective. The RX 7650 GRE’s larger bus and higher clock yield its bandwidth advantage.

The RX 7650 GRE has a boost clock of 2695 MHz and a game clock of 2350 MHz, with a base clock of 1720 MHz. The RTX 4050 Mobile has a base clock of 1455 MHz and a boost clock of 1755 MHz, with no game clock listed. The AMD part’s higher clocks, combined with its larger die and higher power envelope, explain its compute lead. The NVIDIA part’s lower clocks are a direct trade-off for its 50 W power budget.

The AMD card uses a PCIe 4.0 x8 bus interface, as does the NVIDIA part. Display outputs differ: the RX 7650 GRE offers one HDMI 2.1a port and three DisplayPort 2.1 outputs, while the RTX 4050 Mobile’s display outputs are listed as “Portable Device Dependent,” meaning they are determined by the laptop manufacturer. The RX 7650 GRE is a dual-slot card with a 204 mm length, while the RTX 4050 Mobile is an IGP with no published dimensions.

Head-to-Head Benchmarks

The database records only one direct head-to-head comparison: Geekbench OpenCL. In that test, the AMD Radeon RX 7650 GRE scores 83109, and the NVIDIA GeForce RTX 4050 Mobile scores 74748. The delta is 11.2 percent in favor of AMD. This is a meaningful margin in a compute-oriented benchmark, indicating that the RX 7650 GRE delivers roughly 11 percent more OpenCL compute performance than the RTX 4050 Mobile.

Beyond that single test, the specification sheet supports the same conclusion. The RX 7650 GRE’s FP32 throughput is 22.08 TFLOPS, which is 145.7 percent higher than the RTX 4050 Mobile’s 8.986 TFLOPS. The texture rate of 345.0 GTexel/s is 145.7 percent higher than 140.4 GTexel/s as well, which makes sense given that both figures scale with clock and shader count. The pixel rate difference is larger in relative terms: 172.5 GPixel/s versus 84.24 GPixel/s, a 104.8 percent advantage for AMD.

Memory bandwidth tells a similar story. The RX 7650 GRE has 288.0 GB/s of bandwidth, while the RTX 4050 Mobile has 192.0 GB/s, a 50 percent advantage for AMD. The RX 7650 GRE’s memory clock of 2250 MHz with 18 Gbps effective is also higher than the RTX 4050 Mobile’s 2000 MHz with 16 Gbps effective.

The RTX 4050 Mobile does win on transistor density. Its 118.9 million transistors per square millimeter is 82.4 percent higher than the RX 7650 GRE’s 65.2 million. This does not translate into higher performance, but it reflects the more advanced 5 nm process node. The RTX 4050 Mobile also has more shading units (2560 versus 2048) and more tensor cores (80 versus none), but its lower clocks (1755 MHz boost versus 2695 MHz boost) and smaller memory subsystem prevent it from converting those resources into higher benchmark scores.
