NVIDIA's RTX 3000 cards make counting teraflops pointless

Specifically, a teraflop refers to the capability of a processor to calculate one trillion floating-point operations per second. Microsoft rates its Xbox Series X custom processor at 12 TFLOPs, meaning that the console is capable of performing 12 trillion floating-point calculations each second.

Microsoft recently revealed details about its Xbox Series Xstating that its graphics processor is capable of 12 teraflops of performance. All that added power will enable higher frame rates and resolution support, as well as hardware-accelerated ray tracing. This performance will be further augmented with Microsoft implementing a custom algorithm for variable rate shading VRSwhich renders a scene at different details depending on where the focus is.

Floating-point calculations are a common way of gauging the computational power of computers. In fact, once we started using FLOPs, it quickly became a common international standard for talking about computer prowess.

From a computational standpoint, a floating-point calculation is any finite calculation that uses floating-point numbers, particularly decimals. This is far more useful than looking at fixed-point calculations which use only whole integersbecause the work that computers do frequently involves finite floating-point numbers and all their real-world complications.

FLOPS measure how many equations involving floating-point numbers that a processor can solve in one second. Manufacturers frequently include FLOPS as a specification on computers so they can talk about how fast they are in a universal way. In some cases, this assumption is correct.

The phenomenon is similar to wattage. Even if it has the same wattage as another spotlight, it might perform differently. Teraflops use that same logic, considering other factors like processors, frame buffers, and core speed. Researchers who compare specs are now discussing supercomputers that have more than petaflops, and a petaflop is a thousand teraflops.

PC-era moxie lives anew at supercomputer show. Research lab eyes next hardware move as it upgrades to new supercomputer.This is a project I've been wanting to work on for a long time - since it became clear that AMD's brand new Navi architecture would feature in the next-gen consoles, in fact.

From PS4 and Xbox One, through the enhanced consoles and up to the reveal of Google Stadia, graphics power has been measured by a somewhat arbitrary unit: the teraflop. And let's be clear: how many teraflops the new consoles have remains a preoccupation for many observers, eager to get some idea of what PlayStation 5 or Project Scarlett may deliver up against the hardware of today.

But perhaps the focus needs to shift and maybe we need to take a closer look at the new AMD Navi architecture itself. Put simply, a teraflop of Navi compute should produce much faster game performance than an old-school GCN equivalent - but can we quantify that?

Testing Navi - and its teraflops - sounds like a relatively simple task. You'd start by tracking down graphics cards across the last seven years of AMD history, starting all the way back at GCN 1. From there, we'd equalise shader count, core clocks and memory bandwidth across the various GCN iterations and stack them up against a similarly specced Navi. Unfortunately, carrying out this procedure is somewhat difficult because equalising frequencies, compute units and memory bandwidth is essentially impossible.

With that hurdle overcome, some mathematical shenanigans can get us to where we need to be, as this table demonstrates. A video breakdown of our GCN 1. We can't compare GCN 1. The plan is starting to come together - we can compare GCN 1.

However, working back from the top-end, the RX has 36 compute units, which presents a problem. In short: we can't compare GCN 1. This leaves just one more minor challenge - matching core frequency. The RX clock does wander a little, even when drastically underclocked to this level, but not to any degree that's likely to unduly compromise the result.

Game on - but now the next challenge is to figure out what we're actually going to test on all four cards. There's a lot to cover here and we're starting with some synthetic benchmarks to set the stage. But before we go on, let's just stress that this is an architectural performance analysis and not representative of the actual products - remember that we've altered core clock, memory bandwidth or both sometimes quite drastically in order to get an idea of how AMD's graphics technology has evolved over the last seven years.

Firestrike shows a 23 per cent boost in throughput between Tahiti and Polaris, and a lesser 18 per cent uplift from Polaris to Navi. End to end, by stacking up those two percentage gains, the improvement is around 45 per cent overall.

The usefulness of 3DMark is often called into question, but as we'll see on the next page, this figure is close to actual gaming performance under DirectX TimeSpy stress-tests a card's DX12 credentials and produces an eye-opening result.

Polaris beats Tahiti by 38 per cent, while Navi exceeds Polaris by 36 per cent. The question is: are we looking at a genuine architectural improvement here though, or is Tahiti simply lacking a decent DX12 implementation by today's standards?

Spoilers: we're going to see some crazy results running the same workloads across the AMD generations over the next few pages, where the GCN 1.

Polaris vs Tahiti sees a 28 per cent increase in compute power, despite identical levels of rated compute and memory bandwidth. Navi vs Polaris sees another leap of the same magnitude. From Tahiti to Navi, a notional 32 CU part based on the new architecture would deliver a 62 per cent improvement in compute power.

I've also included the tessellation result as an example of AMD has beefed up geometry processing over the years. We know about game benchmarks being limited by compute power, ROPs or memory bandwidth - but could we see games being held back simply by triangle set-up?

Yes indeed. Now it's time to apply the same methodology to a range of games.Teraflops have been a popular way to measure "graphical power" for years. Unfortunately, teraflops have never been less useful.

These numbers are calculated by taking the number of shader cores in a chip, multiplying that by the peak clock speed of the card and then multiplying that by the number of instructions per clock. This sort of "hidden" improvement can be attributed to many factors, from architectural changes to game developers making use of new features, but almost every GPU family arrives with these generational gains. The point is that, even within the same GPU company, with each year, changes in the ways chips and games are designed make it harder to discern what exactly "a teraflop" means to gaming performance.

All of which brings us to the RTX series. These arrived with some truly shocking specs. For context, the RTX Ti, as of right now the best "consumer" graphics card available, has 4, "cuda cores.

Each of the Ti's 68 "Turing" SMs contain, among many other things, 64 "FP32" cuda cores dedicated to floating-point math and 64 "INT32" cores dedicated to integer math calculations with whole numbers.

The big innovation in the Turing SM, aside from the AI and ray-tracing acceleration, was the ability to execute integer and floating-point math simultaneously. This was a significant change from the prior generation, Pascal, where banks of cores would flip between integer and floating-point on an either-or basis. The 's "5, cuda cores" are perhaps better described as "2, cuda cores, and 2, cores that can be cuda. As games have become more complex, developers have begun to lean more heavily on integers.

The downside of the Turing SM is the potential for under-utilization. Coupled with all the other changes Ampere brings, the could outperform the Ti by perhaps 10 percent, assuming the game doesn't mind having 8GB instead of 11GB memory to work with. In the absolute and highly unlikely worst-case scenario, where a workload is extremely integer-dependent, it could behave more like the On the other hand, if a game requires very little integer math, the boost over the Ti could be enormous.

DF saw a 70 to 90 percent lift across generations in several games that NVIDIA presented for testing, with the performance gap higher in titles that utilize RTX features like ray tracing. With the first RTX cards arriving in weeks, you can expect reviews to give you a firm idea of Ampere performance soon.

FLOPS stands for floating-point operations per second. Floating-point arithmetic is the common way to crunch numbers in game development.

Without getting too lost in the weeds, floating-point operations make it easier for computers to work more efficiently with a wider range of numbers. The most common way to express flops is in the single-precision, floating-point format, FP This means the computer is using 32 bits to store data in that format. The most common way to express teraflops for GPUs right now is single-precision.

In the real world, floating-point is much easier for game creators to use with 3D graphics. Game visuals would look and behave poorly, and the code would be, generally, less efficient. The more flops a GPU can do, the faster the data can be processed, and the more computing power there is for running games.

The original Sega Dreamcast had 1. A few years later, the original Xbox was rocking 20 gigaflops 20 billion flops. The PlayStation 3 had close to twelve times that, at Each console got significantly better than its predecessor, due, in large part, to graphics computing power. The PlayStation 5, meanwhile, maxes out at New architecture does usually mean better performance than previous cards, even with similar hardware specifications.

The new console GPUs will also have an impressive number of computing units at high clock speeds: 52 at 1. Microsoft and Sony say their consoles will hit 60 frames per second at 4K resolution in AAA titles typically the most demanding games for graphics.

Microsoft is also looking to hit frames per second at 4K for esports games, which are usually less demanding in terms of graphics. Given the chaos that ensues in esports, smoother visuals are a big plus.

In addition to improved performance at higher resolutions, the new consoles will also support ray tracing. Ray tracing boosts lighting effects within a game, often with dramatic improvements. It also offers a more dynamic, lifelike gaming environment in which shadows and reflections are more realistic. The computing power teraflops available inside the upcoming GPUs will also help these new features.

Think of a teraflop like a math test for your graphics card. Floating-point operations are more complicated than calculations that only involve integers numbers that have no decimals. So rather than measuring these speeds in regular FLOPS, it has become necessary to measure them in teraflops, which translates to 1 trillion floating point operations per second.

Teraflop figures can provide a quick comparison of raw computing power. For instance, the original Xbox One has a 1. Many games are able to run at higher resolutions and higher, smoother frame rates on the more powerful Xbox.

The PlayStation 5 has a But more powerful consoles can often have certain advantages that we might see between the PlayStation 5 and the Xbox Series X. For instance, when the PlayStation 4 launched with its 1.

Do teraflops matter? Loading commentsWhat's more interesting to us, however, is how it compares with PC graphics cards. Microsoft is presumably referring to single-precision floating point FP32 performance, as these metrics typically do.

There are different ways of looking at this. It's also nipping at the heels of the Ti by 1. Other factors dictate performance too, however, such as the underlying architecture, memory configuration, and so forth.

What is a teraflop?

These are the chips that will bring hardware support for real-time ray tracing, and presumably faster performance coupled with better power efficiency. Microsoft and Sony are both using custom silicon from AMD for their next consoles, but this gives us a rough idea of what to expect from the PC versions. There probably will not be a direct equivalent on the PC. However, it's a safe assumption that we will see both slower and faster variants in graphics card form.

Given what Microsoft has just revealed, there is every reason to believe that upcoming Navi cards will be equal to and potentially faster than Nvidia's current top offering in the consumer space. At least until Nvidia rolls out its next-gen cards as well Ampere. This part will not necessarily be true on PC. It looks as though AMD's next-generation Navi parts will bring parity to a card that already exists. This will allow more games to be played at 4K on AMD hardware, but 4K gaming itself is already attainable.

As far as gaming performance goes, Microsoft is claiming "support for up to fps. We already knew the latter was coming, and the former was anticipated. DXR is the Microsoft API powering most of today's ray tracing workloads in games, and VRS is a technique to optimize a GPU's resources by reducing the shading rate in areas of an image "with little or no reduction in perceptible output quality.

The Xbox Series X is scheduled to arrive during holiday AMD has already confirmed we will see next-gen Navi GPUs for the PC this year as well, though it's not yet clear if they will arrive before or after the upcoming console launches. At least now we know what to expect in terms of performance, though.
