这块Radeon RX 6600 XT显卡是很典型的中端显卡设计风格，其采用的散热解决方案预示着发热并不会太高。不清楚这块显卡是公版还是OEM厂商使用的版本，这与此前泄露的Radeon RX 6600 XT公版显卡渲染图有所区别，不少用户更期待Radeon RX 6600 XT能有渲染图那种Mini-ITX规格的产品。在上个月，华擎在日本地区展示DeskMini Max主机的时候，曾有一块名为AMD Radeon P120 ITX的Mini-ITX显卡，据推测很可能就是Radeon RX 6600 XT。

除了泄露了Radeon RX 6600 XT显卡的外观，用户还提交了鲁大师里的测试成绩，显示可以击败某些GeForce RTX 3060 Ti甚至个别GeForce RTX 3070 Ti。当然，这样的成绩只能作为参考，实际性能要等发布后才真正清楚。

Radeon RX 6600 XT将配备完整的Navi 23核心，拥有2048个流处理器，而Radeon RX 6600则拥有1792个流处理器，同时显存位宽都是128位，显存为8GB的GDDR6，有32MB的Infinity Cache。而Radeon RX 6600的流处理器则会和Radeon RX 6600M一样，即1792个，显存容量可能是4GB或8GB。

据Fudzilla报道，通过他们的消息源得知，AMD将于8月11日同时发布Radeon RX 6600 XT和Radeon RX 6600显卡，板卡厂商也会很快跟进推向零售市场。即便面向移动和工作站市场，同样采用Navi 23核心的Radeon RX 6600M和Radeon Pro W6600(M)早已发布，但AMD对于桌面版的产品并没有透露多少信息。

据VideoCardz报道，根据两位油管管主得到的信息，基于Navi 23核心的Radeon RX 6600 XT显卡将会在8月份推出，但没有关于Radeon RX 6600显卡的消息。按照此前PowerColor同时添加两款产品的做法，Radeon RX 6600/RX 6600 XT应该会同时或相隔不远的时间点发布。至于价格方面，Radeon RX 6600 XT的官方建议零售价为399美元，这比预期要高得多，仅仅比Radeon RX 6700 XT低了80美元，似乎没有完全拉开差距。

据了解，Radeon RX 6600 XT仅通过AIB厂商发布各自的产品，AMD网上官方商城也不会销售这款公版显卡，这对于喜欢那款公版显卡的用户来说会有点失望。不过此前华擎曾展示类似设计的未知显卡，当时推测就是Radeon RX 6600 XT，即便没有公版卡销售，AIB厂商应该也会推出类似的产品。

据VideoCardz报道，AMD的合作伙伴们似乎已经有点等不及了，作为核心AIB厂商的PowerColor近日已经在官网的产品类别里添加了Radeon RX 6600/RX 6600 XT这两款GPU，不过PowerColor没有列出具体会是什么系列的显卡，又或者列出规格数据等详细信息，但PowerColor这个举动预示着新产品离消费者应该不远了。

在今年年初CES 2021展会上，AMD曾表示计划在2021年上半年推出Radeon RX 6600系列。在上半年，AMD推出了四款采用Navi 23核心的产品，分别是Radeon RX 6600M、Radeon Pro W6600和Radeon Pro W6600M，面向移动和专业市场，同时特斯拉新的车载信息娱乐系统也采用了这款GPU，但桌面版的Navi 23核心产品迟迟未见。

据VideoCardz报道，他们近期收到了新的渲染图，显示的是一张小型显卡，采用的应该是Mini-ITX规格，配备了单8Pin外接电源接口（图片不清晰被修改过），黑色和银色搭配的散热器，再辅以红色边条点缀，和其他RDNA 2架构的公版显卡类似。爆料的人士称，这是Radeon RX 6600 XT公版显卡的照片，其采用的Navi 23核心配置了2048个流处理器，以及8GB的GDDR6显存。

AMD在发布Radeon PRO W6600的时候提供了关于Navi 23核心的晶体管数量以及尺寸等信息，但AMD并没有把所有规格参数都公开。作为特斯拉在新的车载信息娱乐系统上使用的GPU，加上移动平台和可能的桌面平台，在未来几个月，Navi 23核心很可能是最受欢迎的RDNA 2架构GPU，当然这不包括Xbox Series S/X和PlayStation 5使用的RDNA 2架构芯片在内。

据了解，Navi 23核心应该拥有32个计算单元，但是至今发布的产品都没有使用完整版本的核心（特斯拉使用的芯片其规格没有得到官方确认），最多只用了28个。无论Radeon PRO W6600（M）还是Radeon RX 6600M，流处理器数量都是1792个。近期另外一项规格得到确认，在海外论坛上，其相关管理人员联系了AMD，确认了Navi 23核心拥有64个光栅单元（ROP），这方面与Navi 22核心是一样的。

不少用户正急切等待桌面平台推出Radeon RX 6600/RX 6600 XT显卡，相比此前推出的其他Radeon RX 6000系列产品，搭载Navi 23核心的显卡更符合主流用户的需求。

上半年即将过去，但直到目前为止，AMD的承诺并没有全部实现，比如更多的Radeon RX 6000系列桌面GPU。虽然推出了Radeon RX 6700 XT/RX 6900 XT LC两款产品，但当时AMD首席执行官苏姿丰博士身后背景上的双槽单风扇的Radeon RX 6000系列显卡至今仍未见到，这很可能是属于Radeon RX 6600系列的产品。

推特用户@KOMACHI_ENSAKA发现，在近期AMD发布的最新驱动程序中，实际上隐藏了Radeon RX 6600/RX 6600 XT两款GPU的信息，其PCI设备ID都是73FF，因为这与移动平台Navi 23核心的ID是一样的。

根据最近有显卡厂商向欧亚经济委员会（EEC）提交的资料来看，Radeon RX 6600 XT将配置8GB的GDDR6显存，不过Radeon RX 6600的显存规格暂时还不能不确定。或许距离Radeon RX 6600/RX 6600 XT的发布已不会太远了，对于主流用户来说，更需要这种定位和规格的显卡。

据TechPowerup报道，作为第三款基于RDNA 2架构的芯片，Navi 23拥有110.6亿个晶体管，相比Navi 10的103亿个晶体管在数量上更多。Navi 23的核心面积约为237平方毫米，相比Navi 10约251平方毫米的核心面积也更小一些。同样采用7nm工艺制造，晶体管数量增加了约7.37％，面积则缩小了约5.57％。虽然流处理器数量少了，但晶体管数量更多，这应该是无限缓存的原因造成的。

根据此前的消息，AMD Radeon RX 6600系列台式机显卡将采用Navi 23核心，其中Radeon RX 6600 XT将配备完整的核心，拥有2048个流处理器，而Radeon RX 6600则拥有1792个流处理器，同时显存位宽都是128位，显存为8GB的GDDR6，32MB Infinity Cache。不过暂时仍不清楚，其接口是PCI-Express 4.0 x8还是x16。

AMD Radeon RX 6600系列将采用Navi 23核心，其中Radeon RX 6600 XT将配备完整的核心，拥有2048个流处理器，而Radeon RX 6600则拥有1792个流处理器，同时显存位宽都是128位，显存为8GB的GDDR6。显存配置这点上，已经在之前华擎向ECC提交的文件中确认了，基本没疑问。据VideoCardz称，Radeon RX 6600 XT的3DMark Time Spy图形分数是9439分，Radeon RX 6600则是7805分。另外，两款显卡的哈希率分别是30 MH/s和27 MH/s。这样的挖矿能力，希望矿工们不会那么疯狂。

相比于竞争对手英伟达，AMD在新一代RDNA 2架构GPU的产品线上，部署速度比较慢一些。鉴于产能紧张，为了照顾自己旗下不同产品线的需要，GPU似乎也不是最优先的部分。即使已发布一段时间的Radeon RX 6700/6800/6900系列产品，在市场上交易的数量也比英伟达GeForce RTX 30系列少很多。
