经过调查，这些显卡还有一个共同点，许多都是出自同一个卖家，这意味着有可能显卡上的芯片曾长期“锻炼身体”。由于这些显卡外观看起来都非常新，很可能回收后经过了翻新，然后再重新出售。更让人想不到的是，“锻炼身体”可能并非最主要的原因，长时间存放在高湿度环境里影响更大，这也解释了为什么会出现GPU开裂。据推测，这些显卡在高湿度环境里存放了几周甚至几个月的时间。除了存放的环境，长距离运输过程中的气候变化也值得关注。

这些Radeon RX 6800/6900系列显卡很可能退役后仍然是正常运行的，但糟糕的高湿度存储环境让其“浸泡”在水中，在这期间也没有适当的除湿操作。不少玩家抗拒二手显卡是有道理的，大量的“退役运动员”可能就是定时炸弹，特别经过翻新后变得更难以分辨。

虽然目前Radeon RX 6x50 XT系列的规格大致已经清楚，但一直没有定价方面的消息，以其规格来说，只能猜测大概与原版接近。据VideoCardz报道，Radeon RX 6x50 XT系列的官方建议零售价会比之前对应的产品略有提高，其中Radeon RX 6950 XT的MSRP为1099美元，相比Radeon RX 6900 XT提高了100美元；Radeon RX 6750 XT的MSRP为549美元，相比Radeon RX 6700 XT提高了70美元；Radeon RX 6650 XT的MSRP为399美元，相比Radeon RX 6600 XT提高了20美元。

据了解，AMD会在其官方商店直接销售Radeon RX 6950 XT和Radeon RX 6750 XT公版，均采用公版的散热设计，不过并没有Radeon RX 6650 XT，这意味着该款显卡很可能没有公版散热设计的零售款式。

据VideoCardz报道，Canada Computers & Electronics似乎成为了第一家确认推出Radeon RX 6x50 XT系列公版显卡的零售商，外观设计上与此前泄露的新显卡渲染图一致。

Wccftech则表示，Radeon RX 6950 XT的游戏频率和Boost频率分别达到了2100 MHz和2310 MHz，相比Radeon RX 6900 XT提高了4%，可提供23.65 TFLOPs的FP32峰值性能，功耗将提高到335W；Radeon RX 6750 XT的游戏频率和Boost频率分别达到了2495 MHz和2600 MHz，相比Radeon RX 6700 XT提高了3%，可提供13.31 TFLOPs的FP32峰值性能，功耗将提高到250W；Radeon RX 6650 XT的游戏频率和Boost频率分别达到了2410 MHz和2635 MHz，相比Radeon RX 6600 XT提高了2%，可提供10.79 TFLOPs的FP32峰值性能，功耗将提高到180W。

Radeon RX 6900 XT OC Formula是采用风冷散热设计的RDNA 2架构产品里，性能最强的显卡之一。其配置了三个8Pin外接电源辅助供电，采用了21相供电设计，基础频率为2125 MHz，高于公版的1825 MHz，高出了约10%。华擎还设置了两种BIOS模式，分别是Q模式（静音）和P模式（性能）。在Q模式下，GPU的游戏频率为2165 MHz，加速频率为2365 MHz。在P模式下，GPU将在2295 MHz〜2475 MHz的频率下运行。

相信Radeon RX 6950 XT OC Formula也会有类似的设计，而且相比公版有着更高的出厂频率。

相比过去一年多的时间，现在整个Radeon RX 6000系列的供应情况要好很多，预计对应型号全面更换成Radeon RX 6x50 XT系列并不需要太长的时间。按照AMD的思路，新旧款产品应该具有相同的建议零售价，而不是提高定价。

暂时还不能确定Radeon RX 6x50 XT系列的所有细节信息，即便是传言中速率为18 Gbps的显存也不一定准确，可能不同型号之间还存在差异，根据目前曝光的PowerColor Radeon RX 6650 XT Hellhound来看，显存速率似乎应该是17.5 Gbps。此外，Radeon RX 6x50 XT系列或许会有更高的核心频率，功耗也会略微升高。

值得注意的是，过往Radeon RX 6700 XT/RX 6600 XT分别是双风扇和单风扇的散热器，不过此次Radeon RX 6750 XT/RX 6650 XT则分别换成了三风扇和双风扇配置，这意味着功耗和发热量可能会有所提高，同时也可以预期性能会更强。据了解，这两款公版产品都会通过AMD官方商店出售。

除了更高速率的GDDR6显存，暂时还不能确认GPU的频率是否会有提高，在接下来的大概一个月里，可能会有更多的信息。此外，原本面向OEM的Radeon RX 6400也将在同一天推向DIY市场，这很可能是AMD在消费市场最低端的RDNA 2架构独立显卡。

如果有玩家期待FidelityFX Super Resolution 2.0，那么应该要降低预期了，虽然AMD此前曾提及会继续发展FidelityFX Super Resolution，并且在某个时间点会提供新的版本，但现在还不是时候。目前距离RDNA 3架构的发布还有大概半年的时间，AMD或许会配合新GPU来进行更新。由于AMD将源代码开放给所有游戏开发者，FidelityFX Super Resolution 1.0相当成功，已经有大量的游戏采用，不过接下来的压力不仅来自于英伟达的DLSS，还有英特尔的XeSS。

AMD还有一项名为Radeon Super Resolution（RSR）的技术，这是由FidelityFX Super Resolution 1.0的算法演变的版本，内建在驱动层面上，只有RDNA和RDNA 2架构GPU才能支持，不过AMD一直没有确认什么时候可用。

此外有网友透露，AMD下个月将发布的RDNA 2架构Refresh产品，也就是Radeon RX 6x50 XT系列中，旗舰级的Radeon RX 6950 XT公版显卡将采用全黑配色的外观。不清楚Radeon RX 6x50 XT系列都是如此，还是Radeon RX 6950 XT公版显卡存在特殊版本。去年AMD就曾发布Radeon RX 6800 XT“Midnight Black（午夜黑）”版本，这款限量产品就有别于原来的Radeon RX 6800 XT公版显卡配色。

据Wccftech报道，AMD计划在4月20或21日，发布这些RDNA 2架构的Refresh产品。此外，AMD还可能会将基于Navi 24的Radeon RX 6400推入DIY市场。作为整个Radeon RX 6000系列里最低端的显卡，AMD曾表示Radeon RX 6400仅限于OEM市场。

虽然之前有消息指出，Radeon RX 6x50 XT系列可能还会在频率等方面进行调整，不过也可能仅升级显存而已。将显存速率从目前的15 Gbps提高到18 Gbps，显存带宽将相应增加，TGP或许会有些许提高，预计GPU性能会略高于现有的对应型号。

Radeon RX 6950 XT的竞争对手应该是英伟达的GeForce RTX 3090 Ti，传言其加速频率可能会超过2.5 GHz，TDP将增加到350W。最新的消息指GeForce RTX 3090 Ti会在这个月底推出，即便时间是准确的，也比最初的计划晚了两个月。英特尔在下个季度，将发布Intel Arc（锐炫）品牌的Alchemist显卡，Radeon RX 6750 XT/RX 6650 XT可以巩固AMD现有的产品线位置，以免让对手有机可乘。

与最早的传言有所不同的是，Radeon RX 6x50 XT系列里没有了Radeon RX 6850 XT，不过却增加了Radeon RX 6650 XT。虽然Intel Arc（锐炫）品牌的Alchemist显卡与英伟达GeForce RTX 3070 Ti 16GB即将到来，不过AMD似乎并打算通过Radeon RX 6850 XT压制。

这也不难理解，毕竟搭载Navi 21的型号已经很多了，而原有Radeon RX 6700 XT和Radeon RX 6600 XT两者间却存在空隙，而这个位置更贴近主流玩家，竞争会更加激烈。另外一个原因是，通过此次更新可以使Navi 21、Navi 22和Navi 23都使用速率为18 Gbps的显存，而Navi 24因为发布的时候已经提供了18 Gbps规格的显存，所以并不需要再另外更新。

Radeon RX 6950 XT的竞争对手应该是英伟达的GeForce RTX 3090 Ti，传言其加速频率可能会超过2.5 GHz，TDP将增加到350W。不过目前GeForce RTX 3090 Ti遥遥无期，英伟达对其原因也一直保持沉默。

近日有网友透露，Radeon RX 6950 XT的加速频率可能会超过2.5 GHz，比原有的Radeon RX 6900 XT高了至少250 MHz，也比Radeon RX 6900 XT Liquid Cooled（LC）高了大概65 MHz。此前有报道指出，AMD会选择在今年六月或七月发布Radeon RX 6x50 XT系列显卡，但最新消息指，Radeon RX 6950 XT会在四月中旬推出。由于今年AMD还将发布基于RDNA 3架构的Navi 3x系列GPU，也就是Radeon RX 7000系列显卡，所以Radeon RX 6x50 XT系列应该不会等太久。

一直传言Radeon RX 6x50 XT系列包括了Radeon RX 6950 XT/RX 6850 XT/RX 6750 XT三款产品，涵盖了Navi 21和Navi 22两款芯片，但有网友表示AMD并没有Radeon RX 6850 XT的计划。事实上，基于Navi 21核心的型号已经相当多了，目前已经有Radeon RX 6800/RX 6800 XT/ RX 6900 XT/RX 6900 XT LC四款，加上至少一款Radeon RX 6x50 XT系列产品，搭载Navi 21的型号将达到五或六款，与英伟达采用GA102的型号相当。

 Radeon RX 6950 XT的竞争对手将是英伟达的GeForce RTX 3090 Ti，后者已在CES 2022上公开。其拥有10752个流处理器，基本频率为1560 MHz，加速频率为1860 MHz，配有24GB的GDDR6X显存，速率达到21 Gbps，加上384位的显存位宽，理论显存带宽超过了1 TB/s。英伟达原计划在今年1月份公布更多细节，但是最后却不了了之，暂时也不清楚具体的发售时间和价格。

近日，德国零售商Mindfactory已开始向普通客户单独出售这款显卡，信息显示属于PowerColor的产品（产品代码AXRX 6900XT 16GBD6-MW2DHC），价格为1749欧元，而且还有库存。事实上，该零售商发售这款显卡已经有一段时间了，大概一周前还出现了1679欧元这样相对低的价格。

与风冷版的Radeon RX 6900 XT相比，Radeon RX 6900 XT Liquid Cooled除了采用120mm规格的一体式水冷散热器外，TGP也由300W提高到330W，不过仍然只配置了两个8Pin的外接电源接口。其游戏频率提高到了2250 MHz，Boost频率则提高到2435 MHz，同时拥有更快的显存，达到了18 Gbps，这使得最大带宽增加到了576 GB/s。

近日，Bare Feats发布了相关的基准测试成绩，包括了Octane Render在内的多项内容创建类测试，比较了多款Radeon RX/Radeon Pro在内的AMD产品。如果将Radeon Pro W6800X Duo与以往英伟达RTX A6000的成绩对比，显示在Octane Render基准测试中比RTX A6000快了14%，这项测试以往通常是英伟达的显卡有更好的表现。此外，Radeon Pro W6800X Duo也比Radeon Pro Vega II Duo和Radeon Pro W6900X分别快了17.6%和36.4%。

Radeon Pro W6800X Duo是目前AMD RDNA 2架构里唯一的双芯片显卡，采用MPX模块设计，属于苹果Mac Pro独占产品，暂时仅Mac Pro 2019款可以使用，从Apple Store购买需要5000美元。Radeon Pro W6800X Duo的技术特点如下：

搭载两颗Radeon Pro W6800X GPU，每个GPU拥有60个CU，即3840个流处理器。

每个GPU配备32GB的GDDR6显存（显存带宽为512GB/s），共有64GB的GDDR6显存。
