NVIDIA GeForce MX550 dGPU Barely Outperforms The AMD RDNA 2 ‘Radeon 680M’ Integrated GPU In Gaming

Submit

NVIDIA's recently released GeForce MX550 discrete GPU has been tested and it barely outperforms an AMD RDNA 2 'Radeon 680M' integrated GPU.

AMD's Integrated RDNA 2 GPU Is On Par With NVIDIA's Discrete GeForce MX550 35W GPU While Offering Superior Efficiency

The NVIDIA GeForce MX550 uses the Turing TU117 GPU. Based on the information we had earlier, the chip is a cut-down configuration featuring 1024 CUDA cores, a clock rate of up to 1320 MHz, a 2 GB GDDR6 memory interface running across a 64-bit bus at 12 Gbps clocks, and a TDP that's rated at 25W. While the GPU is based on the Turing chip, it lacks RT and DLSS capabilities since its using a GPU that's a step below the RTX offerings.

The AMD Radeon 600M series integrated GPUs, based on the RDNA 2 graphics architecture, are what's adopted by the Ryzen 6000 APUs, offering up to 12 Compute Units for 768 cores and up to 2.4 GHz GPU frequencies. The Radeon 600M GPUs pack a 50% large compute engine than the early Vega iGPUs, 50% higher bandwidth, twice the L2 cache, and twice the render backends (RB+).

The Radeon 600M is split into two SKUs, the Radeon 680M which is featured on Ryzen 9 & Ryzen 7 chips, packing the full 12 CU & 2.4 GHz configuration (4 RB+). This particular review included AMD's Ryzen 7 6800H which has the Radeon 680M running at 2.2 GHz instead of the full 2.4 GHz on high-end HX parts. The Radeon 660M powers the Ryzen 5 APUs with up to 6 CUs, 1.9 GHz clocks and 2 Render backends. Both chips were tested within these benchmarks.

AMD RDNA 2 Radeon 600M iGPU vs NVIDIA GeForce MX550 dGPU (Synthetic Benchmarks):

So coming to the performance metrics, the AMD Radeon 680M ended up 25% faster in 3DMark Fire Strike, 5% faster in Time Spy, and since it features ray tracing capabilities unlike the NVIDIA discrete GPU, it won the Port Royal benchmark uncontested. Meanwhile, the Radeon 660M which has half the compute units was only able to match in performance to an Intel Alder Lake Core i7-1280P CPU with Iris Xe graphics.

AMD Ryzen 7000 ‘Raphael’ CPU Specs & Price Rumors: Ryzen 9 7950X 24/16 Core Up To 5.4 GHz, Ryzen 9 7900X 12 Core Up To 5.3 GHz, Ryzen 7 7800X 8 Core Up To 5.2 GHz, Ryzen 5 7600X 6 Core Up To 5.1 GHz

AMD RDNA 2 Radeon 600M iGPU vs NVIDIA GeForce MX550 dGPU (Gaming Benchmarks):

Moving from synthetic to gaming benchmarks, a range of titles were tested at 1080p which include both AAA and eSports games. In 9 of the 14 games, the AMD Radeon 680M iGPU was able to out-perform the NVIDIA GeForce MX550. The Radeon 660M was able to beat the Intel Iris Xe iGPU in a total of 13 out of 14 titles.

Overall, the NVIDIA GeForce MX550, despite its discrete and higher TDP design, was only able to offer 5% higher performance than the AMD Ryzen 7 6800H's integrated solution, the Radeon 680M. The Ryzen 5 6600H was able to deliver a 39% uplift over Intel's Iris Xe iGPU. Once again, the 2.4 GHz Radeon 680M has the potential to even surpass the GeForce MX550, and it's impressive coming from an integrated chip that is competing against a discrete GPU that consumes around 35W of power.
