If, for example, a workload is 25-percent integer math, around a quarter of the GPU’s cores could be sitting around with nothing to do. The downside of the Turing SM is the potential for under-utilization. An NVIDIA slide from the original 2018 RTX launch suggested that integer math, on average, made up about a quarter of in-game GPU operations. The 3070's "5,888 cuda cores" are perhaps better described as "2,944 cuda cores, and 2,944 cores that can be cuda."Īs games have become more complex, developers have begun to lean more heavily on integers. With this switch, NVIDIA is now counting each SM as containing 128 FP32 cores, rather than the 64 that Turing had. Ampere keeps the 64 FP32 cores as before, but the 64 other cores are now designated as "FP32 and INT32.” So, half the Ampere cores are dedicated to floating-point, but the other half can perform either floating-point or integer math, just like in Pascal. The RTX 3000 cards are built on an architecture NVIDIA calls "Ampere," and its SM, in some ways, takes both the Pascal and the Turing approach. 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 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. Each of the 2080 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). NVIDIA cards are made up of many "streaming multiprocessors," or SMs. For context, the RTX 2080 Ti, as of right now the best "consumer" graphics card available, has 4,352 "cuda cores.” NVIDIA, then, has increased the number of cores in its flagship by over 140 percent, and its teraflops capability by over 160 percent. And the new $1,500 flagship card, the RTX 3090? 10,496 cores, for 36 teraflops. The RTX 3070, a $500 card, is listed as having 5,888 cuda (NVIDIA’s name for shader) cores capable of 20 teraflops. These arrived with some truly shocking specs.

Take an AMD card and an NVIDIA card of any generation and the comparison has even less value. 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.

That's why the Xbox Series X, for example, is expected to outperform the Xbox One X by more than the “12 versus 6 teraflop” figures suggest. 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. Almost every GPU family arrives with these generational gainsĪMD’s RX 580, a 6.17-teraflop GPU from 2017, for example, performs similarly to the RX 5500, a budget 5.2-teraflop card the company launched last year.

In contrast to many figures we see in the PC space, it's a fair and transparent calculation, but that doesn’t make it a good measure of gaming performance. 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. The most popular GPU among Steam users today, NVIDIA's venerable GTX 1060, is capable of performing 4.4 teraflops, the soon-to-be-usurped 2080 Ti can handle around 13.5 and the upcoming Xbox Series X can manage 12. The term teraflop comes from FLOPs, or "floating-point operations per second," which simply means “calculations that involve decimal points per seconds.” Tera means trillion, so put together teraflops means “trillion floating-point operations per second.” Unfortunately, teraflops have never been less useful. With GPU core counts reaching five figures, it’s nice to have a simple point of comparison. The term refers to the number of calculations a GPU can perform, but while it’s been on spec sheets forever, more recently the teraflop has gone mainstream, appearing in marketing messages found in the launch of consoles like the Xbox Series X. Teraflops have been a popular way to measure "graphical power" for years.
