    AMD Radeon RX 580, Radeon RX 570 and Radeon RX 550 3DMark Benchmarks Surface.

    The first benchmarks are out for AMD’s Radeon RX 500 series and the results are, well, they’re exactly what you’d expect them to be really. The Radeon RX 500 series is a Polaris GPU refresh with some minor architectural improvements. This translates to 5-15% performance gains across the board, effectively phasing out the RX 480, RX 470, etc.

    AMD Radeon RX 580 4GB & AMD Radeon RX 580 8GB
    Let’s start things off at the top of the heap with the Radeon RX 580, which will be available in both 4GB and 8GB versions. In terms of specs the Radeon RX 580 8GB and Radeon RX 580 4GB are going to be identical to the RX 480 8GB & 4GB, aside from a bump in clock speed. The RX 580 GPU is clocked at 1340MHz Boost, whereas the RX 480 was 1266MHz. Aside from this they’re identical. It’s still got 2304 cores, 144 TMUs, 32 ROPs and 6.17 TFLOPs of compute performance. As for the all-important price - the Radeon 580 will be $199 for the 4GB model and $249 for the 8GB GDDR5 variant.

    The 3DMark Fire Strike Extreme benchmarks we’ve got our hands on are for the Radeon RX 580 8GB, overclocked to 1500MHz. The score of 6,390 is decent. A non-overclocked RX 480 8GB pulls in around 5,300.

    AMD Radeon RX 570 4GB & AMD Radeon RX 570 8GB
    Next up is the middle ground, the Radeon RX 570. Once again this is going to be available in 4GB and 8GB versions, priced at $149 and $199 respectively. You’re going to be paying an extra $50 for the 8GB model, and it’s unlikely you’re actually going to be able to use the additional VRAM effectively if you’re at 1080p or below. The cut-down Polaris 10 chip isn’t really viable for higher resolutions than 1080p either, so the 4GB version seems like the safe bet.

    Once again we’re looking at minor step up from the predecessor, the RX 470. Ordinarily a stock clocked 470 can pull in about 4,500, rising to about 5,000 with a decent overclock. Crucially, it’s marginally faster performance for the exact same price. $149 really isn’t a bad price point, and this is the equivalent GPU being used in the PlayStation 4 Pro. If you want a console quality experience on the budget, this is the way to go right now.

    AMD Radeon RX 550 4GB & AMD Radeon RX 550 2GB
    Lastly there’s the tiny Radeon RX 550. There was no RX 450, so this is more along the lines of an RX 460 equivalent. This is a new low-end member of the Radeon family which is powered entirely through the PCI Express slot, and it’s designed to run all the mainstream eSports games. It’s going to struggle a little with playing the likes of Battlefield 1 and The Witcher 3, but it’ll be great for Rocket League, DOTA 2, CSGO, StarCraft 2, etc. It’s going to be available in 2GB and 4GB versions. The 4GB model will be $99, no word on the 2GB version just yet. You may run into a few problems running games if you opt for the 2GB version, so keep this in mind.

    With a trio of new graphics cards on the way from AMD, and each available in two different variants, is anyone tempted to upgrade? Or are you still playing the waiting game for AMD RX Vega? Let us know!
