AMD Radeon RX 6600 vs NVIDIA GeForce RTX 4050 Mobile Comparison

# NVIDIA GeForce RTX 4050 Mobile vs AMD Radeon RX 6600

The NVIDIA GeForce RTX 4050 Mobile and AMD Radeon RX 6600 are remarkably close in overall benchmark performance, with average scores of 19,049 and 19,036 respectively — a delta of just 0.1% in NVIDIA's favor. Both cards sit at the 63rd percentile of all GPUs, placing them in the same performance tier despite their very different designs and target platforms. The head-to-head benchmark data reveals a split decision: AMD wins six of nine tests, while NVIDIA takes three, but the magnitude of those wins tells a more nuanced story than the raw win count suggests.

Head-to-Head Benchmarks

The GeForce RTX 4050 Mobile's most dominant victory comes in Geekbench OpenCL, where it scores 74,748 against the RX 6600's 28,850 — a staggering 159.1% advantage. This is the single largest margin in any benchmark between the two cards, and it highlights NVIDIA's substantial lead in compute-oriented workloads through that particular API. The RTX 4050 Mobile also wins Geekbench Vulkan with 75,235 versus 67,623, a solid 11.3% margin that demonstrates stronger performance in modern graphics APIs.

In DirectX 12, the NVIDIA card again comes out ahead, scoring 61 to AMD's 51, a 19.6% advantage. This is particularly notable because DirectX 12 is the foundation of most contemporary game engines, suggesting the RTX 4050 Mobile may hold an edge in current-generation titles. The remaining NVIDIA win is narrow in context — it's the only DirectX test where the mobile card takes the lead.

The AMD Radeon RX 6600 counters with victories across several legacy and compute benchmarks. Its largest win is in Passmark G2D, where it scores 889 versus 633, a 28.8% advantage that indicates superior 2D and desktop compositing performance. In DirectX 10 the RX 6600 leads 95 to 79 (16.8% ahead), and in DirectX 11 it scores 152 versus 130, a 14.5% margin. The RX 6600 also wins Passmark DirectX 9 with 197 to 184 (6.6% ahead), Passmark G3D with 15,096 to 14,423 (4.5% ahead), and Passmark GPU Compute with 6,554 to 5,947 (9.3% ahead).

The overall average scores tell the real story: these are essentially tied GPUs. The 0.1% delta in NVIDIA's favor is well within measurement noise, and the fact that both cards list the same nearest rivals — including the Quadro K6000 at 19,030 and the Tesla K20m at 19,089 — confirms they occupy the same performance bracket. The RTX 2000 Ada Generation trails both at 18,954, while the Tesla K20m leads the group by a hair.

Architecture Differences

The two cards represent fundamentally different design philosophies. The RTX 4050 Mobile uses NVIDIA's AD107 chip built on Ada Lovelace architecture, manufactured on TSMC's 5 nm process. It packs 18,900 million transistors into a 159 mm² die, achieving a transistor density of 118.9 million per square millimeter. The RX 6600, by contrast, uses AMD's Navi 23 chip on RDNA 2.0 architecture, built on TSMC's 7 nm process with 11,060 million transistors spread across a larger 237 mm² die — a density of just 46.7 million per square millimeter.

Memory configurations differ significantly. The RTX 4050 Mobile ships with 6 GB of GDDR6 on a 96-bit bus, delivering 192.0 GB/s of bandwidth. The RX 6600 offers 8 GB of GDDR6 on a 128-bit bus, with 224.0 GB/s of bandwidth. The AMD card's 33% larger memory pool and 16.7% higher bandwidth give it a clear advantage in capacity-bound scenarios, though the NVIDIA card's memory runs at 16 Gbps effective versus 14 Gbps on the RX 6600.

Core configurations reveal opposite approaches. The RTX 4050 Mobile has 2,560 shading units, 80 TMUs, and 48 ROPs, alongside 20 ray tracing cores and 80 tensor cores. The RX 6600 has fewer shading units at 1,792, but more TMUs (112) and ROPs (64), plus 28 ray accelerators. NVIDIA's higher shader count and tensor cores enable its AI and DLSS capabilities, while AMD's higher TMU and ROP counts drive its texture and pixel throughput. The pixel rate tells this story concretely: 84.24 GPixel/s for NVIDIA versus 159.4 GPixel/s for AMD — a 89% advantage for the RX 6600.

Clock speeds and power draw differ dramatically. The RTX 4050 Mobile runs at a 1,455 MHz base and 1,755 MHz boost, with a 50 W TDP and no power connectors — it's an integrated graphics package (IGP) by design. The RX 6600 boosts to 2,491 MHz (with a 2,044 MHz game clock) but requires 132 W, a dual-slot cooler, and a 1x 8-pin power connector with a 300 W suggested PSU. The NVIDIA part's 50 W TDP is a fraction of AMD's 132 W, making it suitable for thin-and-light laptops, while the RX 6600 is a desktop card with a 190 mm length and 40 mm width.

The RX 6600 also supports 2:1 FP16 rates (17.86 TFLOPS) versus the RTX 4050 Mobile's 1:1 rate (8.986 TFLOPS), while both cards offer similar FP32 performance at 8.93-8.99 TFLOPS. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 6600 provides fixed display outputs (1x HDMI 2.1 and 3x DisplayPort 1.4a), while the mobile GPU's outputs are portable-device dependent.

Where Each One Wins

The GeForce RTX 4050 Mobile is the clear choice for compute-heavy workloads and modern graphics APIs. Its 159.1% Geekbench OpenCL lead and 11.3% Vulkan advantage indicate strong performance in GPGPU applications and Vulkan-based games. The 19.6% DirectX 12 win suggests it handles contemporary game engines better than the RX 6600. For users prioritizing current-generation game performance, particularly in titles built around DirectX 12 and Vulkan, the NVIDIA card's architecture appears better suited.

The RX 6600 dominates legacy DirectX titles, winning DirectX 9 by 6.6%, DirectX 10 by 16.8%, and DirectX 11 by 14.5%. Its 28.8% lead in 2D performance and 9.3% advantage in GPU compute via Passmark suggest it's the better option for older game catalogs, desktop productivity, and certain compute workloads. The 4.5% G3D win and larger 8 GB memory pool make it attractive for users who play a mix of older and newer titles at lower API versions.

The power envelope is a decisive factor in use-case differentiation. The RTX 4050 Mobile's 50 W TDP and IGP form factor means it belongs in laptops where battery life and thermals matter. The RX 6600's 132 W TDP and dual-slot design make it a desktop component that requires a power supply and case space. These are not interchangeable products — one is a mobile solution, the other a desktop card.

The Verdict

The data shows two GPUs with statistically identical average performance: 19,049 for the RTX 4050 Mobile versus 19,036 for the RX 6600, a 0.1% difference that could go either way in any given workload. Both sit at the 63rd percentile, and their nearest rivals overlap completely. The choice between them comes down to platform and workload priorities rather than raw speed.

Users who need a laptop GPU with modern API support and strong compute performance should choose the RTX 4050 Mobile. Its 50 W power draw, IGP form factor, and leadership in OpenCL, Vulkan, and DirectX 12 make it the sensible pick for mobile gaming and portable workstations. The 6 GB memory pool is smaller, but the efficiency advantage is substantial.

Desktop users with a broader game library spanning older DirectX versions should select the RX 6600. It wins six of nine benchmarks, offers 8 GB of memory, higher pixel and texture rates, and better legacy API performance. Its 132 W power requirement is modest for a desktop card, and its end-of-life status means it's a mature product. The RTX 4050 Mobile's wins are bigger in magnitude, but the RX 6600's consistent edge across more tests makes it the better all-rounder for mixed workloads.
