Sapphire Radeon RX Vega 64 Avis | 118 Données comparées

The Sapphire Nitro+ VEGA 64 is a massive, high-performance graphics card designed to maximize the potential of AMD’s VEGA architecture through custom cooling and factory overclocking. Taking up three expansion slots and measuring significantly longer than the reference design, this hefty GPU relies on an innovative vapor chamber cooling solution. The cooling array features two 92 mm counter-clockwise outer fans and a single 80 mm clockwise middle fan to target operating temperatures of 70°C. Physically, it utilizes a 14 nm FinFET architecture with 4096 stream processors, a 1423 MHz engine clock, a 1611 MHz boost clock, and 8 GB of HBM2 memory across a 2048-bit bus. Due to the card's heavy weight, Sapphire explicitly bundles a custom metal support bracket in the box to prevent system droop. A major pro of this graphics card is its exceptional thermal design, which yields a 5°C temperature drop over standard copper bases and delivers up to 7% better framerates compared to reference AMD models. It also includes high-utility hardware features like a Dual BIOS, robust VRM cooling, Black Diamond Chokes, and a quick-connect...

The KitGuru review evaluates the Sapphire RX Vega 64 Nitro+ Limited Edition, a massive enthusiast aftermarket graphics card designed to improve upon AMD's reference architecture. The review highlights several hardware pros, praising its exceptional engineering, which features a robust 14-phase power delivery design, a premium color-neutral aesthetic with subtle RGB lighting, and an advanced cooling system utilizing a massive heatsink with eight heatpipes. In terms of performance advantages, this custom iteration succeeds in delivering significantly lower operating temperatures and much better performance than AMD's standard reference card. It also appeals directly to users deeply invested in the AMD ecosystem, particularly those utilizing FreeSync monitors. KitGuru KitGuru

The KitGuru review evaluates the Sapphire RX Vega 64 Nitro+ Limited Edition, a massive 2.5-slot graphics card measuring 31cm long that heavily improves upon AMD’s reference design by maintaining a stable boost clock of around 1570MHz out of the box. In terms of pros, the card is significantly faster than the reference version, delivering at least 8 more frames on average at 1440p and 4K resolutions in titles like Ashes of the Singularity. Its custom heatsink with a triple-fan configuration provides excellent thermal results, keeping the GPU core at a peak temperature of just 68°C under load. Additionally, it features a stylish, colour-neutral monochrome backplate, an extra HDMI port tailored for VR headsets, and works brilliantly for gamers using 1080p or 1440p FreeSync monitors. However, the card suffers from severe cons regarding power efficiency and value, making it a very tough sell against Nvidia's competition. It is incredibly power-hungry, consuming roughly 40 Watts more than the reference design and requiring three 8-pin PCIe power connectors—prompting a hefty 850W power supply recommendation. Furthermore, at its launch retail price of £749.99 from...
