Geforce 20 Series
The Lenovo Legion Y545 is an entry-level gaming laptop that under promises and over-delivers. The laptop’s discrete Nvidia graphics chip serves up a surprising amount of power, with above-average results. And when you’re not gaming, the laptop’s Core i7 processor is more than capable of allowing you to create spreadsheets, do some light video-editing and, of course, watch some movies on that beautiful 1080p display. We didn’t think Asus could improve on the excellent ROG Zephyrus G14, which easily earned a spot on our best gaming laptops page, but we were wrong.
Other cards in the comparison include the Pascal-basedGTX 1080 Founders Editionand GTX 1080 Ti Founders Edition, and the AMD Radeon Vega 64. The RTX 20 series is based on the Turing microarchitecture and features real-time hardware ray tracing. The cards are manufactured on an optimized 14 nm node from TSMC, named 12 nm FinFET NVIDIA . New example features in Turing included mesh shaders, rRay tracing cores , tensor cores, dedicated Integer cores for concurrent execution of integer, and floating point operations. In the GeForce 20 series, this real-time ray tracing is accelerated by the use of new RT cores, which are designed to process quadtrees and spherical hierarchies, and speed up collision tests with individual triangles.
The RTX 3080 will deliver 4K 60 fps performance, so if you have the display to take advantage of that, then it’s a compelling card. This all translates to DLSS being better at smartly rendering crisp high-resolution graphics gtx 1090 without causing a reduction in frame rates. This revolutionary architecture, combined with our all-new GeForce RTX™ platform, fuses together real-time ray tracing, artificial intelligence, and programmable shading.
That’s something you can already do with existing cards, but the 2080 gives you a lot more headroom for better settings today and more challenging games in the future. Our brief tests of the DLSS demo showed potential for some of the performance gains it could bring, but you shouldn’t spend cash on a card and hope it will get better in time. Nvidia assures us it won’t be long before 25 games will support DLSS, and at least 11 will have ray tracing in the coming months. The NVIDIA GeForce RTX 2080 Ti GPU is based on NVIDIA’s Turing architecture, which brings real-time ray tracing and AI-powered DLSS 2.0 to creators and gamers.
The Turing TU102 and TU104 are both larger than the Pascal GP102, even though the TU104 has 20 percent fewer cores and fewer memory channels. There may be others, but realistically most PC gamers aren’t going to buy the , since you can build a complete mainstream gaming PC for the same price. I’ve reviewed the GeForce RTX 2080 Founders Edition separately, and even that card is tough to recommend at $799. The RTX 2080 Ti tips the scales at 18.6 billion transistors, which also makes it the largest consumer GPU Nvidia has ever created.
To further increase reliability, we designed the fan to be IP5X dust resistant, which means dust won’t be able to damage its internal components. 144-Hour Validation Program puts cards through a series of stringent tests to ensure reliability.

However, the RTX 2080 fails to completely break the 60 fps barrier of 4K gaming. During our testing, we ran the Epic Infiltrator benchmark, which stacks a version of the experience up temporal anti-aliasing against DLSS. The former was able to maintain a frame rate between rendered a minimum of 34 frames per second and maximum of 117 fps, while the later churned out between 35 and 89 fps. Whether you’re looking for a more powerful graphics card or get a jump start on Nvidia’s vision of a ray-traced future, the GeForce is the world’s most powerful GPU on the market. We test over 150 different models per year, subjecting each system to a series of rigorous benchmarks that provides a complete picture of performance, battery life and usability.
Alternate frame rendering has each alternating card prepare the next frame, essentially multiplying the capabilities of a single card’s maximum capable frame rate output. Each card in the configuration can also be used to improve anti-aliasing by being able to process an image in parallel with the other cards before filtering out jagged edges. As part of the RTX 20 Series, the NVIDIA GeForce RTX 2080 Ti graphics processing unit includes ray tracing and artificial intelligence capabilities. What makes active ray tracing so important is the ability to simulate the behavior of light on objects and the transformative effects of surfaces and textures on how it is rendered. In other words, ray tracing attempts to simulate how light waves actually behave in the real world with shadows, reflections, refractions and global illumination.
DLSS becomes even more important given the hit to performance that ray tracing brings. I benchmarked Metro Exodus with and without DLSS while ray tracing was enabled to discover what extent Nvidia’s new technology had on performance. By using DLSS, the Nvidia RTX 2080 Ti can use artificial intelligence to help create an image that’s similar in quality to that which you’d produce with traditional rendering methods. Well, this method actually saves on the GPU’s performance power, helping the GPU run more efficiently, resulting in smoother video. All of these visual effects are subtle, sure, but they genuinely do help to add even more polish to an already beautiful world. Activating DXR means that you’ll take a significant hit to your frame rate, as the technology is so intensive that the GPU has to work extra hard to render it.
