日本电子维修技术 显卡请教显卡问题关于转换2k(Topaz Video Enhance
偶然接触到Topaz Video Enhance AI这款软件,真的很不错。我想把一些视频转换成1080甚至4K。
目前显卡R290 4G,cpu E1230V2,自己日常lol和暗黑玩游戏没问题。就是这款软件转换揪心
准备先换显卡。然后再换cpu套装。具体哪个便宜到心里价位就换哪个。
cpu套装目前暂定5600X+550B。
就是显卡拿不准!我个人而言对我来说换显卡基本就是为了这套Topaz Video Enhance AI转换速度快才考虑(但是没有实际数据对比不知道)。
目前R290基本0.5~0.2帧一秒,普通片要开两三天机,这完全不可用。而且这个软件是nv弄出来,说nv显卡有加成(就是不知道加成多少)。坦然对我来说
3070ti和6700XT在5600X这套东西上,用这个软件转速速度到底有多少?nv显卡在这套Topaz Video Enhance AI是否真的有加成(如果加成不明显我肯定谁便宜买谁)
到底转换速度有多块,要是换了这套东西还是要2天开机,我也就不换了........
不考虑游戏效果,因为这个显卡对我来说都游戏参能过剩的.......
另一个帖子已经找到模型

这玩意儿不是已经支持A卡吗
不过别想N卡能提升多快
我用3090 1080转成4k一样慢
从来没真正转换过一个完整的视频 最长的是是3分钟左右 转化几个小时...
评论
我看到有拿这个去**姐马赛克的,一部1080p的片子3080好像要跑快10个小时
评论
3080Ti就可以了,测试过1080Ti 3070 3080Ti 3090这几张卡,速度上后2张卡很接近,但是价格上80Ti最有性价比
评论
你那个是弄4k,不一样。我就弄1080过度。
另外有资料,内存大,频率高,cpu猛 提升才大。
评论
我觉得没那么猛吧,去马赛克,理论上是贴图上去推算,看上去怪怪的。
评论
我用6900xt提老电视剧的分辨率速度挺快,但不知道是设置问题还是啥原因转换的效果很不理想
评论
因为以前有薄码时代,所以马赛克的与实际图形真实色区域是一致的,所以能用超分算法去算,效果肯定不能做到完美,但是已经很可以了,后来厚码完全无规则就效果不好了,但是也勉强能算
评论
怨不得显卡贵啊 原来还能还原一些原来看不到的地方
评论
你们都不说用的什么模型就在那里报用时,没对比意义的啊

另外水区帖子我已经找到模型参考了。其实就这个软件来说,预算有限。第一投入应该是内存32G~64G 3600 以上,效果更佳

Factors influencing the performance of models in VEAI.
Gaia uses GPU completely so CPU performance will have very little impact.
Artemis and Theia use both GPU(80-90%) and CPU(10-20%), so the performance here will depend on the CPU a lot more.
All decoding/encoding is done on the CPU, so an older CPU will lead to slower performance unless using older codecs or uncompressed image formats like TIF.
PCIe bandwidth is very important when doing higher resolution upscaling. If using a PCIe 4 compatible GPU performance will vary a lot between an AMD 3rd gen or above processor supporting PCIe 4 vs any AMD/intel processor/motherboard not supporting it.
Always ensure that you have adequate power supply to power both the CPU and GPU at peak loads.
We try to use as many cores on the CPU as possible but most of the code is optimized for 4-8 core processors, more than 8 cores may not increase performance as expected. This will be addressed in the future.
Similarly RAM usage is optimized for 16-32GB and VEAI will not take advantage of more memory than that.
GPU VRAM optimizations are currently set at MAX VRAM of around 12GB, so if you have a card that is greater than 12GB in VRAM, run multiple instances on the same GPU for better throughput.
Disc speed matters a lot too especially when reading/writing large uncompressed image/video files. But in most cases will have minimal impact.
For NVIDIA only:
Starting with version 1.7 VEAI does not use CUDA for processing and uses DirectML. So the actual GPU usage when checking in task manager will show up under Graphics_1.
GTX performance is about 10-20% lower compared to 1.6.1 and earlier version due to a driver/library issue and will be fixed in the near future.
RTX with its FP16 tensor core support has superior performance than CUDA(2-3x) via TensorFlow, while the entire model is able to take advantage of the FP16 processing, There are certain layers in the models which also take advantage of the hardware level tensor core kernels to get unto 20x speed up. In case of VEAI these layers very few and so overall performance improvements will be still in 2-3x range.
RTX 3000 series performance is still being analyzed and optimized, it will take some months before superior performance can be achieved for the higher core 3080 and 3090 GPUs.
If you have further questions post them here.
这是VEAI的开发者发的帖子,我粘过来了,内存是为16-32G区间优化的。 电路 电子 维修 求创维42c08RD电路图 评论 电视的图纸很少见 评论 电视的图纸很少见 评论 创维的图纸你要说 版号,不然无能为力 评论 板号5800-p42ALM-0050 168P-P42CLM-01 电路 电子 维修 我现在把定影部分拆出来了。想换下滚,因为卡纸。但是我发现灯管挡住了。拆不了。不会拆。论坛里的高手拆解过吗? 评论 认真看,认真瞧。果然有收
