The video explores whether the latest and most powerful GPUs from AMD and Nvidia can handle modern games on an 88-inch 8K OLED TV. The ROG Strix Radeon RX 6900 XT and MSI Nvidia RTX 3090 SUPRIM X, supported by a Seasonic TX-1000 80+ Titanium power supply and a Ryzen 5950X 16-Core CPU, are tested for their 8K gaming capabilities. Key features discussed include Nvidia's GDDR6X memory and DLSS technology, and AMD's Infinity Cache and Smart Access Memory.
The testing reveals that Nvidia generally outperforms AMD by around 25% in demanding games, especially with ray tracing enabled. However, in specific games like CS:GO and F1 2020, AMD shows superior performance. Overclocking trials on both GPUs indicate that AMD offers a smoother gaming experience and better stability, although Nvidia's card exhibits higher peak power consumption.
Despite AMD showing promise in certain areas, the lack of equivalent technologies to Nvidia's DLSS and slower memory bandwidth are limiting factors. The video concludes that while 8K gaming is possible theoretically, current GPU technology isn't practical for all games without using techniques like super sampling. The speaker emphasizes that HDR and higher refresh rates have a more significant impact on gaming experience than 8K resolution at the moment.

In this part of the video, the presenter explores whether the most powerful gaming CPU, paired with top-tier GPUs from AMD and Nvidia, can handle modern games on an 88-inch 8K OLED TV. The GPUs tested are the ROG Strix Radeon RX 6900 XT liquid-cooled edition and the MSI Nvidia RTX 3090 SUPRIM X, which are priced at $1,500 and $2,000, respectively. Both GPUs are overclocked to their maximum capabilities and are supported by a high-efficiency Seasonic TX-1000 80+ Titanium power supply. The video discusses the built-in advantages of each GPU, such as the RTX 3090’s super-fast GDDR6X memory and the RX 6900 XT’s Infinity Cache and Smart Access Memory, which allows the CPU to access all of the GPU’s memory at once. The presenter sets the stage for testing these GPUs on an 8K display to evaluate these features’ impact.
00:03:00
In this part of the video, the presenter discusses setting up their GPU bench with a Ryzen 5950X 16-Core CPU, a fresh install of Windows, and a powerful Seasonic Prime TX 1080 Plus Titanium power supply to ensure no bottlenecks. They are using Nvidia tools to monitor real-time power consumption during their tests. Baseline testing at stock speeds is performed to assess performance in 8K resolution. Although AMD’s VRM is more capable technically, it is slower than the RTX 3080, showing roughly half the speed. The gaming experience without G-Sync enabled is around 55 FPS, but with noticeable judder during panning shots. Though some improvements are expected with overclocking, the game is well-optimized, handling high FPS and significant power draw. The AMD card’s backplate is discussed for its cooling function, and it’s noted that it might compete with Nvidia in 8K gaming.
00:06:00
In this segment of the video, the speaker discusses power consumption, noting it peaked at 384 Watts with an average of around 311 Watts, specifically for the GPU. They then compare the performance of AMD and Nvidia GPUs across various games. AMD’s performance trails Nvidia’s by about 25% in games like Shadow of the Tomb Raider, especially with ray tracing enabled, and when considering Nvidia’s DLSS feature. However, in games like Forza Horizon, the performance difference narrows to approximately 10%, and AMD even outperforms Nvidia in games like CS:GO and F1 2020, indicating higher raw raster performance.
The segment transitions into overclocking, describing challenges with using Nvidia’s GeForce Experience and MSI Afterburner for automatic scans and setting power targets, which often led to system crashes or unstable overclocks. Despite this, manual overclocking allowed a core increase of about 100 MHz and 800 MHz on the memory before stability issues arose, necessitating adjustments to power limits and core voltage, with a caution against increasing voltage excessively.
00:09:00
In this part of the video, the discussion revolves around overclocking a GPU and comparing its performance with a different model. The first GPU, with cranked settings, shows no significant improvement, running at about 65-75 FPS and experiencing noticeable stuttering. Despite the high power consumption (500 peak, averaging 440-450), the gameplay feels less smooth compared to a Radeon card.
When switching back to the AMD Radeon card, the team tries various overclocking settings. They note that, unlike the Nvidia card, the Radeon offers a noticeably smoother experience. By setting the GPU to 2,600 megahertz and adjusting power limits and memory frequency, they achieve up to 15% faster performance. The overall takeaway is that the Radeon card handles overclocking better and provides a more stable and improved gaming experience.
00:12:00
In this part of the video, the speakers discuss the performance and overclocking of AMD and Nvidia graphics cards. They note that the AMD card delivers a smoother experience, particularly in some games like Doom Eternal, though overclocking introduces some stuttering. They observe that AMD’s power consumption averages around 360 to 362 watts. The overclocking headroom for both cards was limited due to pre-applied factory overclocks. AMD showed improvements in games like Shadow of the Tomb Raider, Red Dead Redemption 2, and Forza Horizon but struggled with ray tracing and maintaining performance in more demanding titles. The summary indicates that AMD’s lack of a counterpart to Nvidia’s DLSS technology and slower memory bandwidth is holding it back. The section concludes by suggesting that if AMD had upgraded certain technologies, it could have been more competitive against Nvidia.
00:15:00
In this segment of the video, the speaker discusses the practicality and future of 8K gaming. They highlight that while 8K gaming is theoretically possible with current GPUs like NVIDIA’s RTX 3090, it is not yet practical for all games due to the immense computational demands. They explain that improvements in GPU technology, similar to AMD’s past performance enhancements with the Radeon 7970, are necessary to make 8K gaming feasible. The segment also covers the benefits of super sampling, which improves visual quality by rendering at a higher resolution and then downscaling, and the role of NVIDIA’s DLSS technology. Additionally, it is noted that both AMD and NVIDIA are far from achieving native 8K gaming for AAA titles without relying on upscaling techniques. The speaker concludes by emphasizing that features like HDR and higher refresh rates currently have a greater impact on gaming experience than 8K resolution.
00:18:00
In this part of the video, the speaker highlights the RTX 1000’s excellent performance and directs viewers to check out the product via a link in the video description. Additionally, they mention that there are various power supplies available to fit different budgets.
