要是主机能用多好啊,特别是第一方独占,深度优化定制不是问题。可惜,PS5买了还是得买块3080 ...

其实主机是可以用到类似技术的。AMD自己的FidelityFX啊,降低渲染分辨率然后做上采样。不过还得另外结合抗锯齿。不过这个技术的实际效果是动态的,就是根据实时画面做处理,有时候画面变化几乎没有,有时候变化可见。帧数提升或者负载降低也没有这次新版的DLSS那么高,但我觉得对于一个开源工具来说也足够了。
PC版古墓丽影暗影和怪物猎人冰原就已经有这个功能了,你有这俩游戏的话可以试试看。对显卡有什么要求我倒是不清楚,A卡貌似需要5000系列,N卡反正20系肯定可以用。

说A卡色彩好、N卡傻快,让我感觉穿越回到十几年前,那时的A卡还属于ATI。
当年“宽带山”还叫pchome,论 ...

看你的话也让我感觉一下子穿越回去了,何国源时代的ATI其实也是被皮黄压着,只不过没像现在那么彻底而已!R200的核心当时多么令人期待,结果还不是一样弱于GF2gts !
另G4OO其实是一张蛮不错的2D卡,配合特丽珑显像管的CRT效果超一流,玩玩RTS真的是种享受,可以3D太渣,包括后来的幻日卡也一样!

r200可是镭8500,怎么可能不如gf2gts,当时老黄为了压制可是出了gf3ti500
rv200(镭7500)不如gf2gts倒是真的,因为本质上还是上一代的改良,同样只有2管线6贴图单元,gf2gts、镭8500、gf3、gf4ti都是4管线8贴图单元

以前a卡颜色好是基于a卡一直都是原厂,不像n卡是授权生产,而且硬件用料会放大模拟信号的输出(vga、dvi-i)的质量;m卡也是一样的情况
现在颜色有差异主要是显卡这里还有一层颜色的映射关系(类似于校色档,但不是校色),实际是不分好与坏的,只是个人喜好不同而已

老外的关于色彩的看法,大部分都是觉得A色彩、画质好:

qwertyusen

Nvidia compress colors to achieve higher fps, it is proven already before but Nvidia fans never admitted



Alexander Daum
1年前
@qwertyusen AMD also compresses Colors, but  much less aggressive as it seems. Theoretically delta color compression should be lossless though, so if the colors really are different, there is additional lossy compression on at least one side

When I upgraded from my gtx 980 to the fury x when I played bioshock infinite on an acer b286hk 4k monitor and the amd card had better looking textures and the colors in general I thought the fury x was better image quality.

Good job man, ive testing on ips monitor gtx 760 and hd 7950, and on amd card i see pure black and pure white instead of blended nv image

I always noticed this difference. When I switched from nVidia to AMD, it simply seemed sharper, but I couldn't put my finger on why. I noticed this even from the desktop background, windows logo and so on.

There is a difference in Black Ops 4 as well. Look at the written text at 3:34, the "E15" if that's what it says.

nvidia seems to gain performance by using a lower quality rasterization / picture denoising engine... And it could be that they fiddle with it and adjust it in drivers for every game so they save performance... I own both a rx vega 64 and a gtx 1070 and using my 4K samsung 55" TV in gaming mode i can really see the clarity and detail difference in favor of my vega.


Muhamad Ubaied

I use gtx 1080 and vega 56 be4. I honestly can say the image quality, colour accuracy looks better on AMD compare to nvidia. Try racing games pit both cards side by side, while driving between tress, you will notice it.



Spork Master

@Aron Lee Full rgb doesn't fix image quality, my hd5450 still has better image quality than my 950. Limited to full does not fix image quality difference between amd and nvidia.



Bryan DeCamps
1年前
Side by side, my 1070 gets better fps but my girlfriends 570 looks so much more rich. More saturated. Dunno

Chad Parker
1年前
AMD R9 390 does not use the same(or even any) compression because it had a 384bit memory bus instead of 256bit +compression (cheaper to make likely). Than new amd moved to in mid range and Nvidia did.



SirKnobofCheese

I had a gtx 770 but won a cheap amd 7970 on ebay.I put in my PC and never went back to the gtx 770 because I thought picture was better on 7970.

@Faycal Assaad i've tested at home the 1660ti and 2060 but i think return them because the quality on my screen is beter with my RX 570 ...
I have all tested in the options and used DDU uninstaller and then the official drivers. The 1660ti is very silent and powerful, but what i see on my screen is more beautiful
with AMD cards ...

maybe this is a factor in apple using only AMD cards and building OS to be optimized on the cards?




Juan Manuel Medina

In the Forza Horizon 4, it seems that Nvidia card were doing some kind of Upscaling from a lower resolution to the native one. Maybe they implemented this in their drivers to avoid RX Vega 64 to beat the GTX 1080 Ti?

All my cards were Nvidia my last one was a 1060 when i changed to a Rx580 the first thing i notice is that the colors were better and i ever think textures look better too. No more Nvidia for me.

I noticed this 5 years ago, watching movies/playing games seems more colorful on amd cards, сolors are deeper, richer and natural. Nvidia looks washed out and flat.

When I changed from 4870 to gtx 770 it took a lot of adjustments to get anywhere near as good clarity. Recently upgraded to Vega 64, straight in, no adjustments required, clarity back again :)

I use rx590 new, before use Gtx 1080 ti. I say you difference amd Card much more color and details. I say clearly amd really  Greatest image quality but performance is not beter than nvidia. I buy rx 5700 Xs loss Price and continue amd Card. I use my Sony tv 12 bit and this is an amazing, ı never use nvidia 12 bit Maximus 10 bit. Thank yolu.

I always thought this was BS but goddamn was I wrong. I switched from a 1070Ti (it died on me) to a RX 5700 XT and there is a massive difference in color (even though i enabled full color spectrum in the control panel). I got an 99% sRGB IPS monitor and the percieved difference is massive.

Going from Gtx 980 to a vega 56 i notice better image quality. And i will be sticking to AMD cards in future just for this alone. plenty other stuff i perfer with Radeon cards too, multiple monitor setup dosn't make your mouse feel weird like it did on my Nvidia card. and the drivers are amazing these days!

I changed recently r9 390 to gtx 1080 and i noticed worse colors and i can't reach as sharp image as i did with amd texture filtering quality at quality. If you change color to auto from amd's control panel it looks much better than nvidia

I moved from RX580 8gb to 1070ti and it feels worse... I'm using Omen 32 monitor with amd free sync.(since this year also supported by nvidia) I made clean windows reinstall last weekend with latest drivers and still it feels worse. like there are some micro hiccups and image is not so good... I can even see micro hiccups while watching Netflix. My girlfriend  can't see it but it almost makes me sick... does anyone has similar experience?"

I did when I switched 270x to 1060. I am visual guy and image on nvidia was/ is unaccaptable. Not just game, even desktop is ugly. i Do use color profile to iron it out but it is still miles away compared to old amd. I Notice it the most in games where I don't use any anti-aliasing. For example  rocket league. Edges are jagged, textures are shit and color is meh. Amd should really market on this when they clearly have superior picture. Its like comparing super amoled vs some low tier screen. Also, games run a lot smoother.  I will surely switch to amd when they make silent and low powerconsumption series like they did with ryzen cpus.

I used to laugh at this comparison of graphics card outputting less color.  I used all nvidia cards up until now. Recently i used a rx 460 and it was my first time using an AMD graphics card. And the colors were night and day difference of my gtx 1060. For some reason AMD card outputs much better black levels and colors were more vibrant and saturated. After reverting back to gtx 1060 everything felt whitish. Turns out it is a Nvidia driver bug while using HDMI to connect monitor. The driver recognizes the monitor as a TV and output limited RGB colors. Then I changed the limited RGB output to Full (0-255) and everything is just as vibrant and well saturated as the AMD card now. Its a bug that still exists now

帮助ATI成长为行业领头羊

2002年下半年,ATI的R300架构正式问世,首发产品为全球首块支持DirectX 9.0的显卡——Radeon 9700 PRO。

Radeon 9700 PRO的DirectX 9.0性能、抗锯齿性能以及各向异性过滤性能异常出色,一举击溃了当时一家独大并自恃清高的NVIDIA旗下的旗舰级显卡GeForce 4 Ti4600,就算NVIDIA在半年后被迫拿出自己的首款支持DirectX 9.0的显卡-GeForce FX 5800 Ultra也无法抵挡Radeon 9700 PRO的能耗比优势。

Radeon 9700 PRO拯救了处于困难时期的ATI,而王启尚在R300的架构设计工作中起到了至关重要的作用。

正是凭借出色的能耗比,R300为ATI赢得了微软的信任,同年,ATI和微软宣布了一份开发协议:由ATI来为当时的下一代主机XBOX开发图形单元。

这打破了先前微软和NVIDIA的合作关系,意味着XBOX下一代主机的图形部分将更换一位新的合伙人。

2004年,一路高歌的ATI公司的显卡市场占有率已近60%,可谓是显卡行业当之无愧的“一哥”。

在年末ATI放出消息,采用全新的统一渲染架构R500将于次年正式问世,而在接下来的2005年,我们终于见到了微软的第二代主机——XBOX 360,其搭载了代号为“Xenos”的图形芯片,正是基于定制化的ATI R500架构。

Xenos的核心结构与PC的显示芯片截然不同,其整合了10MB显存,用于加快抗锯齿的运算;像素和顶点处理不再分开,同一处理单元可处理像素或顶点数据。

此时的王启尚已经升职为ATI的高级芯片经理,Xenos从最初的构想到诞生都离不开他的领导与努力,而GPU更为的强大表现力也是XBOX 360能够战胜PS3的原因之一。





王启尚作为AMD公司图形卡产品部高级总监,其不仅参与设计了R600这样出色的架构,还是AMD“Fusion”概念的提出人之一,也就是说将CPU和GPU合二为一,让具备不同特性的两种芯片相互协作,而这正是AMD APU的概念雏形。

2008年,AMD发布了基于R700架构的Radeon HD 4000系列的首款产品——Radeon HD 4850,该卡定位中档千元级,但却有着前所未有的硬件规格和性能,是世界上第一款万亿次计算能力的单个芯片(1 TFLOPs)。

当然,还有一些不能忽视的重要特性包括独有的DirectX 10.1支持和先进的PCI-E 2.0总线接口,这些都让Radeon HD 4850站在时代的前沿。

在和NVIDIA同类产品的对抗中,Radeon HD 4850毫无疑问的完胜GeForce 8800 GT,再次颠覆了新品上市的性价比极限。

2009年,AMD抓住Windows 7和DirectX 11 API的契机,率先推出首款支持DX11 API的产品——Radeon HD 5870。

HD 5870采用40nm制程R800架构,流处理器数量比HD 4890整整翻了一倍,核心面积仅增加了不到30%,单精度浮点运算能力大幅提升至2.72 TFLOPs是当时性能最强的单芯显卡,让AMD重登性能王者的宝座。

更令人惊讶的是,规格如此之高的HD 5870的待机功耗却仅为27W,实在是令人难以置信,充分彰显了AMD的技术实力。





任天堂Wii的GPU开发工作依旧由王启尚负责,虽然“Hollywood”的性能并不是很强,远不及XBOX 360的“Xeons”,但其独特的设计充分地诠释了“量身定制”的概念,与Wii可谓是天造地设的一对,而这正是归功于王启尚及团队与任天堂良好的沟通。


聪哥和王大,都是老熟人了。。

你自己粘贴的回复你是不是没看全啊,你复制的最后一个回复很好的为你解释了现在N和A为什么色彩不同以及怎样设置相同,尤其在现今数字信号普及的时代,相同的显示器输出,A卡默认RGB全取色彩看起来浓艳,N卡默认RGB有限色彩看起来发灰发白,最直接的例子就是显示器输出下PS4如果用RGB限制画面会看起来发白发灰,而用RGB全取就没有这个问题,据我所知PS4可没有N卡版吧
