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。

图：华擎 Radeon RX 6900 XT OC Formula

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。

作为单项测试的成绩，并不能完全反映两款产品的实际性能差距，或者游戏中实际运行的情况，最终还是要等Radeon RX RX 6750 XT发布以后，再做详细的测试才能确定。

Radeon RX RX 6750 XT依旧保留了原有Radeon RX 6700 XT的一些基本规格，包括40个CU（2560个流处理器）、96MB的Infinity Cache、12GB的GDDR6显存、位宽为192位等。若显存速率为18 Gbps，那么显存带宽将达到432 GB/s，传闻Radeon RX RX 6750 XT在230W到250W之间。

根据过往的消息，未来接替Ryzen 6000系列的是代号Phoenix的Zen 4架构APU，与代号Raphael的CPU一样，都会支持PCIe 5.0。GPU方面，应该会延续现有的RDNA 2架构，Rembrandt APU配备的Radeon 680M已给人留下了深刻的印象。

近期有新的流言指出，Phoenix APU的CU数量会继续增加，将达到16到24个，这意味着Phoenix APU的CU数量将至少赶上基于Navi 24核心的Radeon RX 6500 XT。对于独立显卡来说，这样的配置或许比较一般，但是对核显而言，这又是一次较大幅度的跃升，理论上性能比Xbox Series S还要强。

自从AMD确立APU开始，一直试图取代入门级独立显卡的位置。虽然APU提供了不错的性能，但是出于多方面的原因，始终有所不足。随着英特尔在GPU上发力，性能渐长，对AMD造成了更大的威胁，且前者的核显在编解码方面有着出色的表现，而这正是AMD近年来相对缺失的部分。

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。

图：Radeon RX 6650 XT Hellhound与原有的RX 6600系列产品似乎没什么差别

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。

据称RX 6400采用Navi 24核心修改而来，只有12个CU、768个流处理器，但仍带有12个光追加速单元，这个规格和AMD今年早些时候推出的锐龙6000系列移动CPU上，那颗RX 680M核显非常相近，甚至核心频率都是差不多的，在2039-2321MHz之间，另外就是带有16MB的IF缓存了，当然作为独显，它配备有4GB GDDR6显存，只是位宽仅为64-bit，带宽也就只有128Gbps。

按照RX 680M核显的性能来推测，AMD这张RX 6400应该还是可以应付不少1080p下的游戏，性能估计接近于GTX 1650，所以对于主要玩玩网游的入门级玩家其实还是够用，但还是要看售价了，此前的RX 6500 XT讲真定价还是偏高一些，不知道这次AMD会不会对游戏玩家们好一点了，可以要留意RX 6400在4月20日的 上市了。

不过随着市场的变化，Radeon RX 6400似乎已不再局限于OEM市场，也会推向DIY市场。此前华擎向欧亚经济委员会（EEC）提交的新文件里，就包含了一款名为“RX6400 CLI 4G”的ITX规格显卡。据VideoCardz报道，AMD主要AIB厂商之一的蓝宝石（Sapphire）也将推出一款名为Radeon RX 6400 Pulse入门级显卡。

相比华擎的Radeon RX 6400，蓝宝石的产品更加小巧，采用了单槽半高的结构，配备了一个DisplayPort 1.4端口和一个HDMI 2.1端口，单风扇的配置足够满足其53W功耗的散热需求。其整体造型与今年年初AMD发布的Radeon Pro W6400非常相像，搭载的Navi 24核心采用6nm工艺制造，配备了16MB的无限缓存，配备4GB的GDDR6显存，显存位宽为64位。

据了解，AMD将会在4月20日开始面向DIY市场发售Radeon RX 6400显卡。根据此前曝光的基准测试成绩，Radeon RX 6400相比Radeon RX 6500 XT的Vulkan分数只低了7%，不过OpenCL分数则低了将近30%。

此外，Radeon RX 6400的PCIe 4.0接口与Radeon RX 6500 XT一样，仅为四通道，加上不支持4K H.264/H.265编码以及AV1解码，相信对于使用PCIe 3.0的旧平台用户来说，吸引力仍然很有限。

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。

随着新款AM4平台CPU/APU的到来，AMD在主流市场上，带来了与英特尔Alder Lake平台对抗的产品，至少一定程度上可以抵御过去几个月来竞争对手的攻势。自推出第12代酷睿系列以后，英特尔在消费端市场上止住了下滑的颓势，接下来年末Raptor Lake的发布，或许会吹响英特尔反攻的号角。

除了CPU/APU以外，传闻AMD会选择5月10日在桌面平台推出Radeon RX 6x50 XT系列显卡，以及将原本面向OEM的Radeon RX 6400在同一天推向DIY市场。不过近期在国内和阿根廷的网上零售商处，都已出现Radeon RX 6400的踪迹，比如泰塔的RX 6400单槽刀卡。根据流出的GPU-Z截图显示，其游戏频率为2039 MHz，加速频率为2321 MHz，而显存速率则为14 Gbps，低于官方所说的16 Gbps。

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。

近日有网友发现，AMD可能会推出第三款基于Navi 24核心的桌面显卡，定位比Radeon RX 6400更低，型号为Radeon RX 6300。AMD已经在最新的3.10版GPU Performance API提供了支持，简介承认了Radeon RX 6300的存在。据悉，Radeon RX 6300的显存仅为2GB的GDDR6，很可能是一款面向OEM的入门级显卡。由于GPU规格进一步削减，性能或许还比不上某些集成显卡。

据了解，Radeon RX 6400应该不再局限于OEM市场，此前已经有厂商向欧亚经济委员会（EEC）提交了新的文件（比如华擎的RX6400 CLI 4G），传言很快会推向DIY市场。

Radeon RX 6500M采用Navi 24，台积电6nm工艺制造（RDNA 2架构中唯一的6nm GPU），尺寸为107 mm²，拥有54亿个晶体管，拥有16个CU（1024个流处理器）。锐炫A370M采用ACM-G11，同样是台积电6nm工艺制造，尺寸为157 mm²，共有72亿个晶体管，拥有8个Xe核心（1024个FP32核心）。从规模上看，ACM-G11大于Navi 24。此外，两者的显存位宽都是64位，配备了4GB的GDDR6显存。

事实上，Navi 24和ACM-G11有着一些共同的特性，比如均使用了台积电的N6工艺，显存有着相同的配置（尽管ACM-G11完整规格是96位）。作为移动GPU，两者的TDP范围也一样，都是35W到50W。

AMD的图表还暗含深意，其设计风格与英特尔在发布会上展示的图表非常相似，多少有点嘲笑的意思。当时英特尔谈及游戏性能的时候非常隐晦，仅仅让锐炫A370M与酷睿i7-1280P的Iris Xe核显做了比较，而且没有标出后者的帧数。

当然，英特尔也有痛击对手的地方。由于Navi 24的PCIe 4.0接口仅为四通道、不支持4K H.264/H.265编码以及AV1解码，在发布后被众多用户吐槽。反观英特尔的ACM-G11，其PCIe 4.0接口为八通道，支持VP9、AVC、HEVC和AV1格式的硬件编解码（其中AV1硬件编码是英特尔首家提供），最高能支持8K60 12-bit HDR硬解码，以及8K 10-bit HDR硬编码。入门级GPU在游戏性能方面或许没那么重要，而英特尔的Xe媒体引擎可能在日常应用中更具优势。

据TomsHardware报道，时隔不到一个月，Mindfactory的AMD Radeon RX 6500 XT售价进一步下降，比如PowerColor的产品，单/双风扇散热的AMD Radeon RX 6500 XT显卡价格分别跌至169欧元/179欧元。相比于德国地区目前的官方建议零售价229欧元（已包含19%的增值税），已低了约26.2%。除了近期显卡价格趋势整体走低以外，Radeon RX 6500 XT配置上的先天不足或许是其价格出现较大幅度下滑的重要因素。

Radeon RX 6500 XT基于Navi 24核心，采用6nm工艺制造，配置了16MB的无限缓存，拥有16个CU，即1024个流处理器，4GB的GDDR6显存，速率为18 Gbps，显存位宽为64位。由于PCIe 4.0接口仅为四通道、显存容量只有4GB、以及不支持4K H.264/H.265编码以及AV1解码，可能对性能或使用上有较大影响，远远低于预期，导致不少消费者望而却步。

目前像GeForce RTX 3080或以上级别的高端显卡价格下跌速度较快，而且有加速的趋势，对于部分消费者来说，或许是一个购买新显卡的好时机。不过受众群体更为广泛的主流级别型号，溢价程度仍较为明显一些。
