Dual Radeon RX 6500 XT V2 OC Edition 4GB GDDR6的整体尺寸为201mm x 128mm x 40mm，看起来非常地紧凑。搭载了双风扇散热解决方案，使用了两个轴流技术风扇，采用双滚珠风扇轴承，具有较小的风扇轮毂，便于使用更长的叶片，以及增加向下气压的阻隔环。支持0dB技术，当GPU低于50℃且功耗较低时，风扇将停止转动，做到完全无噪声污染。配置有金属背板，保护PCB的同时也可以辅助散热，并防止PCB弯曲。

新款显卡搭载了基于RDNA 2架构的Navi 24，采用了6nm工艺制造，配置了16个CU，拥有1024个流处理器，Infinity Cache为16MB，显存为4GB的GDDR6，位宽为64-bit，速率为18 Gbps。华硕做了出厂OC设置，游戏频率/加速频率分别为2670 MHz和2820 MHz。显示输出方面，配备了一个DisplayPort 1.4a接口和一个HDMI 2.1接口。供电接口方面，采用单个6Pin供电接口的设计。

产品采用了华硕的Auto-Extreme技术制造，这是一种全自动化制造技术，可在单次处理中完成所有锡焊任务，不但能减少组件承受的热应变，还能避免使用高酸碱性的清洁化学物。运用该技术能减少对环境的影响、降低生产时的耗电量，还能打造出更可靠的产品。

AMD Radeon RX 6400 Low Profile 4GB采用了50A Dr.MOS搭配90A电感供电设计，并做了针对性的优化；显卡运用了哑光黑色和铜色的配色方案，使得组件看起来更具质感；高密度玻璃纤维PCB设计，减少了PCB层之间的间隙，以保护显卡免受潮湿引起的电气短路；搭配的单风扇支持0dB静酷技术，温度较低时会自动停转，以实现完全静音，温度升高时会启动降温；显示输出方面，配备了一个DisplayPort 1.4 HBR3端口和一个HDMI 2.1端口；支持华擎Tweak应用程序2.0，这是一款专业易用的显示适配器调校工具，是用户调整风扇各项参数与显卡效能的最佳软件。

新显卡基于RDNA 2架构的Navi 24打造，采用了6nm工艺制造，配置了12个CU，拥有768个流处理器，Infinity Cache为16MB，游戏频率和加速频率分别为2039MHz和2321MHz，搭配显存为4GB的GDDR6，位宽为64-bit，速率为14 Gbps。由于整卡功耗仅为53W，并不像许多独立显卡那样，需要外接供电。

华擎为Radeon RX 6500 XT Phantom Gaming 8GB OC做了出厂超频设置，基础频率、游戏频率、加速频率分别为2420 MHz、2685 MHz和2825 MHz。显示输出方面，仅提供了一个DP 1.4接口和一个HDMI 2.1接口。

华擎暂时没有公布Radeon RX 6500 XT Phantom Gaming 8GB OC的定价，以及具体的上市时间。

据Wccftech报道，AMD Radeon RX 6300最近出现在Geekbench的数据库里，其搭载在Dell新款OptiPlex SFF 7010小型主机上，进行了OpenCL测试。其成绩为25608分，要知道Radeon 780M在同一基准测试中的成绩约为3.5至4万分，领先Radeon RX 6300一大截。

资料显示，Radeon RX 6300拥有12个CU，即768个流处理器，另外应该有16MB的Infinity Cache，显存仅为2GB的GDDR6，显存位宽仅有32位，显存速率为16Gbps，显存带宽不过64GB/s，整卡功耗为32W。

事实上，AMD一直没有真正确认Radeon RX 6300的存在，即便OEM厂商也是如此。不过近日就有Radeon RX 6300现身二手交易平台，采用了单风扇散热，是一张单槽半高卡，价格为399元。作为一款面向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。

Radeon RX 6300的显存仅为2GB的GDDR6，显存位宽为64位，速率为2000MHz，也就是16Gbps，相比Radeon RX 6400还更快一些，核心频率上与Radeon RX 6300M相同，整卡功耗为32W。暂时还不清楚配备了多少流处理器，但肯定不会高于768个。

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。

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。

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。

近日Radeon RX 6400已出现在了Geekbench上，在基于AMD Ryzen 5 5600X、华擎X570 Taichi和32GB DDR4内存搭建的平台，使用Windows 11操作系统进行了测试。此前华擎曾向欧亚经济委员会（EEC）提交了一款名为RX6400 CLI 4G的产品，这有可能是其零售版本。

近日，德国零售商Mindfactory在周末发布了新的优惠活动，各款Radeon RX 6500 XT都出现了降价，华擎Radeon RX 6500XT Challenger ITX和技嘉Radeon RX 6500 XT Eagle的价格甚至低至199欧元（已包含了19%的增值税），一度低于官方建议零售价（209欧元）。虽然活动结束后，价格有所回升，但部分Radeon RX 6500 XT的价格仍有所降低，比如目前华擎Radeon RX 6500 XT Phantom Gaming D OC的价格为229欧元，低于此前的249欧元，或许离真正跌回官方建议零售价并不远了。

Radeon RX 6500 XT价格走低，或许与其配置有关。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。该款显卡有几个争议点，分别是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。

测试显示，Radeon RX 6500 XT相比于Radeon RX 5700 XT或英伟达GeForce GTX 1650这样一些旧款显卡，并没有什么性能优势，4GB的显存容量要应付最新的游戏可能会力不从心。此外，PCIe仅为四通道的设计导致在PCIe 3.0主板上使用会出现较大的性能损失，同时编解码的缩水也降低了部分用户购买的欲望。

按照AMD的说法，Radeon RX 6400并不会向零售市场发售，仅限于OEM市场。相信华擎这款Radeon RX 6400显卡供应量非常有限，很可能只向特定客户供应。与Radeon RX 6500 XT不同，Radeon RX 6400并不需要配备外接供电接口。此外，Radeon RX 6400的PCIe 4.0接口同样仅为四通道，且不支持4K H.264/H.265编码以及AV1解码。

今天AMD发布了数款搭载Navi 24核心的Radeon PRO W6000系列工作站显卡，包括面向桌面平台的Radeon Pro W6400，以及面向移动平台的Radeon Pro W6500M和W6300M。据了解，所有基于Navi 24核心的显卡应该都会缺少4K H.264/H.265编码以及AV1解码。

据Phoronix论坛上一位名为John Bridgman的用户（AMD的Linux NPI软件架构师）称，AMD之所以在Navi 24核心上大幅度削减编解码功能，原因在于Navi 24主要的用途是搭配代号Rembrandt的APU在笔记本电脑上使用。AMD在CES 2022大展上发布的新一代Ryzen 6000系列APU，采用了Zen 3+架构内核，同时支持USB 4、PCIe 4.0和LPDDR5/DDR5内存。与Navi 24一样，均采用了台积电6nm工艺制造。该系列APU配置了RDNA 2架构的核显，具有完整的编解码功能。

John Bridgman指出，Navi 24应该只是限制了编码，解码部分是完整的，不过不能肯定到底是最后真的削减掉了，还是宣传页面上的信息错误。如果说Navi 24的设计放在移动平台还能说得过去，那么在桌面平台上就很尴尬了。英伟达应该会感到高兴，毕竟GeForce RTX 3050相比起来情况好不少，而且GA107核心仍未在桌面平台出现，将来入门级产品线还有较大的操作空间。

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。该款显卡有几个争议点，分别是显存容量只有4GB、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。

就在Radeon RX 6500 XT正式解禁前夕，KitGuru发现AMD将社区中一篇名为“Game Beyond 4GB”的文章删除。该文章发表于2020年6月份，内容说明了当时AMD想要向PC游戏玩家的想法，配合宣传拥有6GB或8GB显存的Polaris/RDNA架构显卡。AMD希望引导游戏玩家选择Radeon RX 5500 XT 8GB版，而不是4GB版，表示相比英伟达GeForce GTX 1650 SUPER有着性能的优势。

经过一段时间的消失后，文章最终被AMD放回来了。这表示AMD很可能没有直接删除，应该只是隐藏了，至于为什么又放回来，这操作反映的微妙心态变化就比较有趣了，至少能说明一些问题。

事实上，在Radeon RX 6500 XT以及RX 6400推出前，Radeon RX 6000系列其他产品的配置和定位都相当不错，显存配备上相比竞争对手的产品普遍占有优势。这也间接导致英伟达多次更新GeForce RTX 20/30系列产品线，加大了显卡的显存容量。
