据Chips and Cheese报道，根据泄露文件的AM5插槽处理器兼容性列表，AM5平台会有三种类型的处理器，均基于Family 19h（Zen 4）架构，而且都集成了图形单元。按照文件内容的描述，AMD在部分型号的处理器上会禁用图形单元，这种做法和市场定位将和英特尔“F”后缀的处理器类似。

按照之前的传闻，除了代号Raphael的Zen 4架构Ryzen系列处理器外，AMD还将使用RDNA 2架构核显更新Zen 3架构APU，比如面向移动平台、使用FP7插座、代号Rembrandt的APU，而这款APU也有可能在AM4或AM5平台上出现。不过以目前的资料来看，至少AM5平台上不会出现这样的产品，这意味着新平台的APU很可能是代号Phoenix或其他Zen 4架构产品。

还有一点值得注意，就是目前泄露的AM5平台的图片是有不同版本，区别在于右下方负责高速USB设备的4条PCIe Gen4通道。VideoCardz表示，其中一个版本是有专门列出支持DisplayPort 2.0输出，这表明下一代Ryzen系列处理器不但有核显，而且会支持新一代的显示输出标准。

近日，XFX官方就是分享了一张新的渲染图，这款名为Radeon RX 6900 XT ZERO WB的显卡将会是XFX迄今为止最快的GPU，将采用全新的PCB设计。毫无疑问，Radeon RX 6900 XT ZERO WB也会使用特挑的Navi 21 XTXH核心，将是XFX旗下搭载Navi 21核心的显卡里，第一款配备三个8Pin外接电源的产品，会有更强的供电系统，以有效提高核心频率，估计会比公版提高10%以上。

XFX分享的照片显示，Radeon RX 6900 XT ZERO WB将使用EK定制的水冷头，采用全覆盖的设计，正面有一个大大的“X”标志代表XFX，透过亚克力板可以让用户看到水道，同时会有ARGB灯效，并配有金属背板，双槽的厚度。在设计上，Radeon RX 6900 XT ZERO WB与PowerColor的Radeon RX 6900 XT Liquid Devil比较相像，两者都采用全覆盖的EK定制产品，不过XFX的这款显卡看起来更加通透。

XFX还没有确定Radeon RX 6900 XT ZERO WB的发布日期，不过应该不会等太久，不过价格方面肯定也不会便宜。这类型产品的目标用户群是那些追求高性能的水冷发烧玩家或超频玩家，即便与风冷散热的产品有相近的性能，也希望有更好的散热效果。

在Radeon RX 6600 XT的官方建议零售价公布后，不少玩家认为其定位稍微高了些。不过鉴于当下显卡供应不稳定（特别是A卡），而且价格偏高，如果能够以接近官方建议零售价购买一块，也是非常不错的。

近日，新蛋上已经有第三方卖家开始销售微星Radeon RX 6600 XT Gaming X（目前已无存货），价格达到了1099.99美元（约人民币7124元）。即便属于微星定位相对较高的Gaming X系列产品线，微星官方售价或许也高于379美元，但这个价格实在高得有点过分。更麻烦的是，这种偷跑的行为还违反了AMD的协议。

此前，PowerColor的三款Radeon RX 6600 XT显卡（分别属于Fighter、Hellhound和Red Devil系列）出现在新西兰零售商PBTech的网站上，显示的价格均为1248.99新西兰元（含15%税），约合869美元或人民币5636元，也高出官方建议零售价一大截。有欧洲的零售商预期，实际价格在499至549欧元（约人民币3800元至4180元）之间，似乎更接近消费者的期望。

Radeon Pro W6800X和W6900X都是采用单Navi 21核心的产品，前者配置了60个计算单元，即3840个流处理器，单精度浮点计算能力为16 TFLOPs，半精度浮点能力为32 TFLOPs。后者则是完整的80个计算单元，即5120个流处理器，单精度浮点计算能力为22.2 TFLOPs，半精度浮点能力为44.4 TFLOPs。两款显卡的Infinity Cache均为128MB，显存位宽为256位，32GB的GDDR6显存，显存带宽达512GB/s。

旗舰的Radeon Pro W6800X Duo则采用双Navi 21核心，配置了120个计算单元，即7680个流处理器，单个GPU的单精度浮点计算能力为15.1 TFLOPs，半精度浮点能力为30.2 TFLOPs。该款显卡总计256MB的Infinity Cache，单个GPU显存位宽为256位以及512GB/s的显存带宽，共有64GB的GDDR6显存。

据了解，Radeon RX 6600 XT的性能高于英伟达的GeForce RTX 3060，后者的官方建议零售价是329美元，但前者的显存容量不如后者，AMD担心会有客户被这项参数左右选择。此外，即便Radeon RX 6600 XT的传统光栅性能不错而且有FidelityFX Super Resolution，在综合光线追踪性能的情况下，大概也不如GeForce RTX 3060 Ti，而后者的官方建议零售价是399美元。

另外有消息指出，英伟达正在增加GeForce RTX 3060的供应量，以应对Radeon RX 6600 XT的发布。不过现阶段官方建议零售价只有表面意义，根据不同地区零售商渠道的消息和上架的报价，Radeon RX 6600 XT的实际交易价格显然会高出官方建议零售价很多。此前传言欧洲地区Radeon RX 6600 XT的零售价不会低于499欧元（约588美元），而新西兰零售放出PowerColor三款Radeon RX 6600 XT显卡的页面显示，价格甚至高达869美元。

最近PowerColor向欧亚经济委员会（EEC）提交了文件，里面涵盖了三种Radeon显卡，分别是Radeon RX 6600/RX 6600 XT/RX 6900 XTU，所谓Radeon RX 6900 XTU就是基于Navi 21 XTXH的型号，比如Red Devil和Liquid Devil Ultimate系列的产品，传闻新产品会是两款非OC的型号。

PowerColor为即将发布的RX 6600 XT准备了13款不同型号的产品，当然最后不一定全部都会发布，也可能为未来做准备，包括了在新西兰零售商PBTech出现的Fighter、Hellhound和Red Devil系列，其中Hellhound系列与此前Radeon RX 6700 XT一样，都会有白色版本。另一方面，还有11款搭载Radeon RX 6600的产品，包括了Fighter和Hellhound系列，同时似乎印证了该GPU会配备8GB显存。

目前有传闻指官方建议零售价为349至379美元，比之前所说的399美元要低。不过鉴于GPU供应短缺的问题，官方建议零售价几乎没有太大意义，只要短缺持续而且有消费者愿意多掏钱，零售商仍然会高价出货。据Cowcotland报道，Radeon RX 6600 XT实际上市价格可能会比预期高很多，有零售商表示预计价格为499至549欧元。

SiFive在去年推出了一款搭载RISC-V架构SoC的桌面级开发板，名为HiFive Unmatched。

这款Mini-ITX规格的主板基于SiFive FU740 SoC，集成了四个U74-MC内核和一个S7嵌入式内核，带标准的ATX电源连接口，配备了8GB的DDR4内存和32MB SPI 闪存芯片，提供了USB 3.2 Gen 1端口、一个PCI Express x16插槽（x8速率）、一个2280 M.2插槽、一个用于Wi-Fi/蓝牙适配器的2230 M.2插槽、microSD读卡器和千兆以太网。

据hackster.io报道，René Rebe通过修补Linux内核，利用这块开发板，让AMD Radeon RX 6700 XT与RISC-V处理器在Linux系统下运行。他花了十个小时的时间，在Linux系统里增加了对AMD Radeon RX 6700 XT显卡以及Mesa Gallium 21.1.5驱动程序的支持。不仅让Radeon RX 6700 XT显示Linux的GUI，甚至以硬件加速模式渲染3D图形并解码视频。这是第一次有人尝试使用RISC-V处理器与高性能GPU一起工作，而且挺成功的。

据VideoCardz报道，新西兰零售商PBTech在网站上列出了PowerColor三款Radeon RX 6600 XT显卡（目前已删除），分别属于Fighter、Hellhound和Red Devil系列。这些显卡都配备了8GB的GDDR6显存，其中两款还进行了超频，不过没有给出具体的频率。

这几款显卡在页面上显示的价格均为1248.99新西兰元（含15%税），约合869美元或人民币5636元，相比传言中399美元的官方零售价，显然高出了一大截。值得注意的是，PBTech上目前在售的Radeon RX 6700 XT显卡，价格在1248.99~1399新西兰元之间，所以这些搭载Navi 23核心的Radeon RX 6600 XT显卡价格不一定是准确的。
