We went back and retested only to get the same numbers. That being the case you’d expect to see similar gains at 4K when compared to 1440p, however the margin drops down to 10%, which is still an impressive gain but it makes the 1440p data appear quite odd. It’s strange though because at 1440p we see a much bigger 18% performance boost and typically when we see this you’d assume some kind of system bottleneck at 1080p, like a CPU limitation.

At 1080p we’re looking at a decent 7% performance uplift, which is cool considering it’s free performance. Moving on to Hitman 2, we have some strange numbers. The 4K gains are extreme as it takes the experience from somewhat unplayable to playable, and should you dial back the quality preset one setting, the game would be very smooth. The RX 6800 was already faster than the RTX 3070 in this title, now we’re looking at a huge 57% performance advantage.Īt 1440p we’re looking at a 19% performance improvement with SAM enabled and a 17% increase at 4K. We’re looking at a 20% performance uplift at 1080p, taking the RX 6800 from 103 fps on average to 124 fps.

Representing the GeForce camp is the RTX 3070 Founders Edition, while the Radeon GPU is represented by AMD's reference card, both are clocked at stock with no overclocking.Īssassin’s Creed Valhalla is currently the best showing for SAM that we’ve come across. We're using a Ryzen 9 5950X test system, armed with 32GB of DDR4-3200 CL14 memory in a dual channel, dual rank configuration. Everything else is left as stock, which is why we test Intel processors without enforcing the TDP limits, as that’s not the out of the box experience for most Z490 motherboards.īack to today's test, we’ve got the Radeon RX 6800 set up with resizable BAR and 36 games to be benchmarked. Typically, we like to provide out of the box performance, with the only exception being XMP which is literally the only thing we enable for both AMD and Intel systems.

The other key reason is that even with the right processor and motherboard combination, resizable BAR isn’t enabled by default.

For once, it’s supported by a single processor series at the moment, using one of two chipset options. All that nonsense aside, there are good reasons why we don’t test with SAM enabled by default. Radeon RX 6800 comparison, we noticed a small number of people complaining that we didn’t test with SAM enabled and therefore claimed the comparison was unfair, misleading, used poor testing methodology, and so on. We've also heard reports of SAM even working on select Intel Z490 motherboards and separately on Radeon RX 5700 GPUs on B450 motherboards, so that might be something worth exploring eventually. Officially AMD has yet to acknowledge SAM support for 300 and 400 series chipsets (as well as Ryzen 3000 and older processors), but motherboard makers have put in the work and some older motherboards now support the feature. Nvidia has yet to deliver on that promise although it's only been a few weeks since.

Nvidia has also come out to say they will be enabling SAM on GeForce GPUs via a driver update, while stating that they’ve got it working on both AMD and Intel platforms. That makes the feature less appealing and restrictive, even though with some extra work in theory this could be offered on all current AMD and Intel platforms. It’s worth noting that as of writing, AMD's only offering SAM support with the new RDNA2 GPUs when paired with a Ryzen 5000 processors on a 500 series motherboard. Notwithstanding, AMD took a different approach with RDNA2 by using a 256-bit wide memory bus in conjunction with their Infinity Cache, and they felt it was time to take advantage of this feature and squeeze some extra performance that would let them be more competitive against Nvidia's Ampere.

However, for the most part there’s been no need to make any changes to this limit either, as high-end GPUs typically feature wide memory buses and therefore have significantly more memory bandwidth at their disposal when compared to system memory. There’s no real reason why the 256 MB limit exists, it was put in place back in the 32-bit era and hasn’t been altered since.

Typically the CPU can access up to 256 MB of mapped VRAM, but with the resizable BAR it can have full access to the graphics cards' VRAM buffer. While technically SAM is not an AMD-exclusive technology, they are the first to take advantage of the resizable Base Address Register or resizable BAR, a feature introduced with the PCIe 3.0 spec.įor those of you not yet up to speed, SAM or resizable BAR defines how much of your graphics cards VRAM is to be mapped for access by the CPU. All in all, we plan to benchmark 36 games at 1080p, 1440p and 4K. Today we’re taking a detailed look at how AMD’s Smart Access Memory (SAM) technology influences performance in a wide range of games.
