PowerColor宣布，正式推出Radeon RX 7900 XTX Liquid Devil，将为游戏爱好者提供终极超频性能。这是PowerColor最高端的Radeon RX 7000系列显卡，也是首款及迄今为止唯一一款专门针对水冷散热设计的RDNA 3架构产品。目前官网上已经更新了一些资料，不确定以后是否有基于Radeon RX 7900 XT的同系列产品。

Radeon RX 7900 XTX Liquid Devil采用了全新定制版本的EK水冷头，附带了全覆盖定制背板，PCB为14层，配备了复杂的电压调节模块，有三个8Pin外接供电接口。该款显卡提供了双BIOS功能，分别为OC模式金额Unleash模式，后者支持更高的频率和整卡功率。PowerColor还没有放出完整的规格信息，比如频率和供电设计，推测很可能与Red Devil系列一样，采用12+3+2相供电设计（17相核心供电），另外还有2+2相显存专属供电。

相比一般的显卡普遍双槽或三槽厚度不同，Radeon RX 7900 XTX Liquid Devil仅为单槽厚度，显卡显得非常紧凑。其水冷模块支持RGB灯效，玩家可以通过PowerColor Devil Zone RGB软件进行完全自定义的操作。另外PowerColor还为显卡配备了EK-Loop Leak Tester Flex（专门用于PC水冷散热的气密仪）和一个小泵，允许用户以快速且安全的方式自行测试可能存在的泄漏。

近日，PowerColor在社交媒体的官方账号上，放出了Radeon RX 7900 Liquid Devil系列新品的预告。与之前的Radeon RX 6800/6900 Liquid Devil系列一样，继续使用EK的水冷头。如无意外，这将是一个定制版本的EK-Quantum Vector2 RX 7900水冷头，覆盖显卡上的GPU、显存和VRM供电模组，同时还会附带一个定制的背板。

一般情况下，Liquid Devil系列和Red Devil系列显卡都采用了相同的PCB设计，因此Radeon RX 7900 Liquid Devil系列很可能为12+3+2相供电设计（17相核心供电），另外2+2相显存专属供电，配备三个8Pin外接供电接口，提供双BIOS功能。Liquid Devil系列显卡的目标用户群是那些追求高性能的水冷发烧玩家，即使Red Devil系列显卡有着相近的性能，也希望有更好的散热效果。由于PowerColor会为整个Devil系列产品线提供质量最好的GPU芯片，所以频率方面不需要担心。

截至目前为止，只有华擎的Radeon RX 7900 XTX AQUA 24GB OC配备了水冷散热模块。其采用了22相供电和AQUA水冷系统，透明的亚克力板和铝制部件结合，提供了高效的散热且时尚，内置的ARGB LED可以与支持Polychrome SYNC的华擎主板同步灯光效果，允许用户自定义灯效系统。

PowerColor还没有确定新款Radeon RX 7900 Liquid Devil系列显卡的发布日期，有可能会在近期推出，包括XT和XTX型号的产品。

这将是PowerColor旗下标志性系列的新版本，定位高端市场。相比Radeon RX 7900 Hellhound系列，Red Devil系列似乎有着更大的散热模块，供电也进一步做了加强。PowerColor没有透露Radeon RX 7900 Red Devil系列显卡的详细规格信息，不清楚到底是Radeon RX 7900XTX还是RX 7900XT。

AMD在11月3日发布了基于新一代RDNA 3架构GPU的Radeon RX 7900 XTX和Radeon RX 7900 XT显卡，前者拥有6144个流处理器，显存为24GB的GDDR6，显存位宽为384位，显存速率为20 Gbps，显存带宽为960 GB/s，Infinity Cache为96MB，后者采用经过削减的Navi 31，流处理器为5376个，显存为20GB的GDDR6，显存位宽为320位，显存速率为20 Gbps，显存带宽为800 GB/s，Infinity Cache为80MB。

华硕最近率先发布了Radeon RX 7900 TUF Gaming系列显卡，同时Radeon RX 7900 ROG STRIX系列也出现在了提交欧亚经济委员会（EEC）的文件中，不过具体的频率和价格等信息还有待公布，预计与PowerColor的Radeon RX 7900 Red Devil系列和Hellhound系列一样，都将于2022年12月13日上市销售。

据了解，Radeon RX 7900 Hellhound系列显卡可能为2.5槽到3槽的厚度，由铝制鳍片和热管组成了硕大的散热器，隐约可以看到采用了三风扇散热方案，全覆盖的背板甚至延伸到PCB之外，同时PCB似乎采用了定制设计，但保留了公版的双8Pin外接供电接口。背板上有显眼的地狱猎犬标志，并亮起了蓝灯，侧面还带有“Radeon”字样。PCB的背面还有开关，用于控制LED灯，以及BIOS切换。

除了PowerColor以外，华硕最近率先发布了Radeon RX 7900 TUF Gaming系列显卡，同时Radeon RX 7900 ROG STRIX系列也出现在了提交欧亚经济委员会（EEC）的文件中，不过具体的频率和价格等信息还有待公布。

PowerColor是AMD显卡过去十几年的核心合作伙伴之一，已经开始为新款产品开展宣传活动了，涉及的是其主打的Red Devil系列。PowerColor在社交媒体的官方账号上发布了一张图片，上面有红色的Devil标志，很可能属于新一代非公产品。

由于图片只是显卡散热器保护罩的正面局部图，上面没有散热风扇的痕迹，有人猜测PowerColor的新款显卡可能采用了一体式水冷解决方案。VideoCardz还根据之前曝光的Radeon RX 7900系列公版显卡，模拟了可能的设计。

AMD将会在2022年11月3日举办名为“together we advance_gaming”的特别直播活动，推出下一代Radeon显卡。届时AMD高管将详细介绍高性能、高效率的RDNA 3架构，为游戏玩家和内容创作者提供更高水平的性能、能效和功能。具体时间为太平洋夏令时2022年11月3日下午1点，也就是当天欧洲中部时间晚上9点，北京时间第二天早上4点、悉尼时间早上7点。

Radeon RX 6650 XT Hellhound仍支持双BIOS功能，同样具有Silent和OC模式，前者的游戏频率和加速频率分别为2410MHz / 2635MHz，后者的游戏频率和加速频率则为2486MHz / 2689MHz。目前的Radeon RX 6600 XT Hellhound，Silent模式的游戏频率和加速频率分别为2359MHz / 2589MHz，OC模式的游戏频率和加速频率则为2382MHz / 2593MHz，可见Radeon RX 6650 XT Hellhound核心频率上有小幅度的提升。

有趣的是，Radeon RX 6650 XT Hellhound使用的是速率为17.5 Gbps的显存，与传言中的18 Gbps显存略有不同，暂时不确定是什么原因。相比Radeon RX 6600 XT Hellhound，Radeon RX 6650 XT Hellhound的显存带宽从256 GB/s提高到了280 GB/s。

这并不是第一款曝光的PowerColor Radeon RX 6x50 XT系列显卡，此前PowerColor已向RRA（韩国国家无线电研究机构）提交了Radeon RX 6750 XT Devil，型号为“AXRX 6750XT 12GBD6-3DHEOC”，是一款定位较为高端的产品。

随着发布时间的临近，AMD的合作伙伴已经准备新的显卡。近日有网友发现，PowerColor已在3月29日向RRA（韩国国家无线电研究机构）提交了Radeon RX 6750 XT Devil，型号为“AXRX 6750XT 12GBD6-3DHEOC”。原先的Radeon RX 6700 XT Devil是一款定位较为高端的型号，采用了定制的PCB设计和三风扇散热系统，拥有双8Pin外接供电接口。

新显卡依旧保留了原有Radeon RX 6700 XT的一些基本规格，包括12GB的GDDR6显存、位宽为192位、2560个流处理器等。由于显存速率提高到18 Gbps，显存带宽将增加到432 GB/s，比原有产品提高了48 GB/s。传言Radeon RX 6x50 XT系列将会在5月10日发布，届时就能确定核心频率是否有改动。

据DigiTimes报道，有业内人士展望华擎和PowerColor未来业务的时候表示，ABF基板的短缺问题有可能在2022年中左右缓解。目前主要的ABF基板供应商包括了欣兴电子和南亚科技等，这些企业在过去的一段时间里，都投资扩充产能，以进一步提高供应量，这将有助于板卡厂商在今年增加显卡的出货量。

华擎和PowerColor都属于AMD显卡方面的合作伙伴，据称过去几个月里都有着非常强劲的显卡销售量，对整体业绩大有帮助。华擎和PowerColor希望能再接再厉，当ABF基板供应缓解后，可以在2022年下半年逐步扩大显卡出货量。ABF基板供应问题这么快得到解决可能有点出乎意料，要知道在几个月前，有业内人士仍悲观地认为，ABF基板供应短缺的情况有可能一直持续到2025年。

近日，PowerColor推出了一款Mini-ITX规格的AXRX 6500 XT 4GBD6-DH，厚度为双槽，整体尺寸为165 x 125 x 40 mm。其采用了一个双滚珠轴承技术的90mm风扇进行散热，并配有静音风扇技术，以Radeon RX 6500XT的功耗情况，散热方面应该没什么问题。

PowerColor官方介绍里该款显卡配置了一个8Pin外接供电接口，不过提供的产品图片显示的是6Pin外接供电接口。此外还配备了一个HDMI 2.1端口，以及一个DisplayPort 1.4端口。

由于Radeon RX 6500XT仅有4GB显存，PCIe 4.0接口仅为四通道，加上不支持4K H.264/H.265编码以及AV1解码，很可能会影响部分用户的选购。虽然官方建议零售价为199美元，但实际价格可能会高出不少，不过PowerColor并未提供定价和上市时间。

AMD Radeon RX 6500 XT和RX 6400均采用Navi 24核心，配置了16MB的无限缓存、1MB的L2缓存、以及128KB的L1缓存。前者将配置16个CU，拥有1024个流处理器，后者只有12个CU，流处理器数量为768个，但不需要外接供电。两款显卡会配备4GB的GDDR6显存，显存位宽为64位，显存速率为14 Gbps，对应的显存带宽为112 GB/s。

此外，PowerColor还提交了一款名为BC-2235的板卡，很可能是矿卡，最大特征是配备了10GB的显存。暂时还不清楚BC-2235会搭载哪一款GPU，有可能与蓝宝石的GPRO X080是一样配置，采用Navi 22核心，显存位宽为160位，配备10GB的GDDR6显存。

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。

据推特用户@FlanK3rXS介绍，这次来自希腊的OGS团队，使用了PowerColor的Liquid Devil AMD Radeon RX 6900 XT Ultimate，经过多次尝试后，将其超频至3321 MHz，超过了此前德国超频爱好者Der8auer的成绩（3225 MHz），再一次刷新了GPU超频记录。巧合的是，两次刷新记录的显卡均为PowerColor的同一款产品。

不同的是，这次超频记录还附带基准测试结果，显示在3DMark Time Spy Extreme图形测试中取得了41069分，综合得分达到了37618分，这在单GPU排名中取得了第一的位置，十分厉害。目前Navi 21 XTXH核心已经将限制提高到4 GHz，未来在这些定制版Radeon RX 6900 XT显卡上继续使用液氮散热的方式，有可能会不断刷新记录，达到3.5 GHz或更高的频率。
