AV1 encoding is a new generation of video encoding standards developed in cooperation with Google, Microsoft, Apple and other companies, better than H.264/265, smaller capacity and lower bandwidth requirements at the same image quality, AMD, NVIDIA and Intel also support AV1, but the lack of support for low-end cards, which gives the Intel A380 graphics card an advantage.

Video blogger EposVox did a test for this, using Nifty’s VMAF benchmark tool to analyze the AV1 encoding performance of the three, comparing the video quality at 3.5Mbps, 6Mbps, and 8Mbps bit rates, with higher scores being better.

In this test, NVIDIA’s NVENC encoder is the worst performer, with scores of 71 and 85 at 3.5M and 6Mbps respectively. AMD graphics cards are similar to NV’s encoder, and slightly worse, while the Intel A380 graphics card is the best performer, with scores of 83 and 90.

The only thing that comes close to the Intel A380 graphics card is the score under OBS’s x264 VerySlow H.264 preset, which received quality scores of 78 and 88 respectively, but this preset requires a lot of CPU resources and cannot be processed in real-time, so it is meaningless for live streaming.

Previously in 2018, Huawei self-researched GPU Turbo technology, allowing the phone’s GPU performance to be significantly improved, officially claiming a 60% increase in graphics processing efficiency, while achieving greater power savings and ensuring high image quality.

Now Huawei has brought Super Turbo to notebooks. The technology opens up the processing bottleneck between the notebook system and the GPU and CPU, reconfiguring the traditional graphics processing framework at the bottom of the system to achieve software and hardware synergy, allowing the CPU and GPU performance to be fully utilized while also reducing power consumption.

This technology allows for a smoother experience with older notebooks and is worth waiting for.

Yesterday’s comparison was with the RTX 3090 graphics card, with a performance of 72fps, while the RTX 3090 Ti was 80fps, exactly double the performance.

What is the concept of doubling the GPU performance compared to the previous generation? This decade of upgrades has not seen such a large increase, can improve 50% is very good.

Yesterday’s news did not mention a key point – power consumption, 3DCenter website gives the results of 600 + W, that is, more than 600W, this power consumption is not the first time, there are even higher 800W, 900W and other claims, but those are too exaggerated, 600W credibility is still relatively high After all, this happens to be the upper limit of power consumption for graphics cards in PCIe 5.0 graphics cards and ATX 3.0 power supplies.

Specifications, RTX 4090 Ti is also a full-blooded AD102 core, with 144 SM units, that is, 18,432 CUDA cores, with 384-bit bit width, a memory capacity of 24GB.
