Compute & Synthetics

Shifting gears, we'll look at the compute and synthetic aspects of the RX 580. As this is the 3rd time we're seeing 'big' Polaris, there's nothing new to discuss, and with no other design changes we only expect to see the impact of increased clockspeeds.

Beginning with CompuBench 2.0, the latest iteration of Kishonti's GPU compute benchmark suite offers a wide array of different practical compute workloads, and we’ve decided to focus on level set segmentation, optical flow modeling, and N-Body physics simulations.

Compute: CompuBench 2.0 - Level Set Segmentation 256

Compute: CompuBench 2.0 - N-Body Simulation 1024K

Compute: CompuBench 2.0 - Optical Flow

Moving on, we'll also look at single precision floating point performance with FAHBench, the official Folding @ Home benchmark. Folding @ Home is the popular Stanford-backed research and distributed computing initiative that has work distributed to millions of volunteer computers over the internet, each of which is responsible for a tiny slice of a protein folding simulation. FAHBench can test both single precision and double precision floating point performance, with single precision being the most useful metric for most consumer cards due to their low double precision performance.

Next is Geekbench 4's GPU compute suite. A multi-faceted test suite, Geekbench 4 runs seven different GPU sub-tests, ranging from face detection to FFTs, and then averages out their scores via their geometric mean. As a result Geekbench 4 isn't testing any one workload, but rather is an average of many different basic workloads.

We'll also take a quick look at tessellation performance.

Synthetic: TessMark, Image Set 4, 64x Tessellation

Finally, for looking at texel and pixel fillrate, we have the Beyond3D Test Suite. This test offers a slew of additional tests – many of which use behind the scenes or in our earlier architectural analysis – but for now we’ll stick to simple pixel and texel fillrates.

    To be honest I believe that the GTX 1070/Vega 56 is not that far away in price and should be considered as the minimum investment for a gamer in 2019. Reply

    over $600 for a single GPU V56, no thank you..even this 590 is likely to be ~440 or so in CAD, screw that noise.

    minimum for a gamer with deep pockets, maybe, but that is like the price of good cpu and motherboard (such as Ryzen 2700)

    Lol it's not really the rest of the world's fault the Canadian Dollar absolutely freaking sucks right now. Or AMD's for that matter. Reply

    Man, I still have a hard 200 dollar cap on any single component. Kinda insane to imagine doubling that!

    I also don't give a shit about 3d, virtual anything or resolutions beyond 1080p. I mean ffs the human eye can't even tell the difference between 4k and 1080, why is ANYONE willing to pay for that?!

    In any case, 150 is my budget for my next GPU. Considering how old 1080p is that should be plenty.

    4k and 1080p look pretty different. No offence, but if you can't tell the difference, perhaps it's time to schedule a visit with an optometrist? Nevermind 4K, the rest of the world will look a lot better also if your eyes are okay :) Reply

    My eyes are fine. The sole advantage of 4K is not needing to run AA. That's about it.

    Anyone buying a card just so they can push a solid framerate on a 4K monitor is throwing money in the trash. Doubly so if they aren't 4->1 interpolating to play at 1K on a 4K monitor they needed for work (not gaming, since you don't need to game at 4K in the first place).

    There is a big difference between 1080P and 4k... But that is entirely depending on how large the display is and how far you sit away from said display.

    Otherwise known as "Perceived Pixels Per Inch".

    With that in mind... I would opt for a 1440P panel with a higher refresh rate than 4k every day of the week.

    Depends on the monitor. I'd agree with you when people claim "the sweet spot of 4k monitors is 28 inches". Maybe the price is good, but my old eyes will never see it. I'm wondering if a 40" 4k TV will make more sense (the dot pitch will be lower than my 1080P, but I'd still likely notice lack of AA).

    Gaming (once you step up to the high end GPUs) should be more immersive, but the 2d benefits are probably bigger.

    There are people who notice the differences, and those who do not. Back in the days of CRT monitors, most people would notice flicker with a 60Hz monitor, but wouldn't notice with 72Hz. I always found that 85Hz produced less eye strain.

    There is a huge difference between 1080p and 2160p in terms of quality, but many games are so focused on action that the developers don't bother putting in the effort to provide good quality textures in the first place. It isn't just about not needing AA as much as about a higher pixel density and quality with 4k. For non-gaming, being able to fit twice as much on the screen really helps.

    I reached diminishing returns at 1366x768. The increase to 1080p offered an improvement in image quality mainly by reducing jagged lines, but it wasn't anything to get astonished about. Agreed that the difference between 1080p and 4K is marginal on smaller screens and certainly not worth the added demand on graphics power to push the additional pixels. Reply
