Geforce Desktop Gaming Benchmark

Nvidia目前的顶级型号提供了令人印象深刻的性能。我们已经看到这一点的形式是 PalitGeForce RTX 4090 GameRock OC和 NvidiaGeForce RTX 4090 Founders Edition.通过KFA2的版本，我们看一下当前高端级别的另一个模型。

对于这项测试，我们使用KFA2GeForce RTX 4090 SG。制造商认为该显卡与华硕GeForce RTX 4090 Strix和微星GeForce RTX 4090 Suprim X处于同一水平，它们都是各自制造商的顶级型号。不幸的是，我们无法为您提供与这些竞争对手和KFA2GeForce RTX 4090 SG的直接比较，因为我们还没能拿到这两款机型。KFA2模型非常大，这确实也是RTX 4090所有模型的情况。四插槽设计占用了机箱内的大量空间，并承诺在负载下提供安静的显卡。对于风扇，制造商使用了三个直径为102毫米（约4英寸）的大型轴流风扇。它们经过重新设计，提供了高达25%的体积吞吐量。功率消耗为450瓦，也是按照Nvidia的参考模型。与GeForce RTX 4090显卡的所有型号一样，新的12VHPWR连接被用于电源。相应的适配器包括4x 6 + 2针PCIe。

在外部，KFA2GeForce RTX 4090 SG提供1个HDMI 2.1a和3个DisplayPort 1.4a连接。

我们基于AMD Ryzen 9 7950X的测试系统

一个基于Gigabyte X670E Aorus Master的当前AMD平台作为我们的测试系统。该CPU (AMD Ryzen 9 7950X)提供了良好的性能，我们使用Alphacool的AiO解决方案(Alphacool Eisbear Aurora 360 mm)进行冷却。32GB的工作内存来自G.Skill，并以相应的EXPO配置文件运行。对于显示器，我们使用了技嘉的M32U。

关于KFA2GeForce RTX 4090 SG的详细信息

在时钟速度方面，KFA2完全坚持制造商在GeForce RTX 4090 SG的指导方针。有了这个，在纸面上为GPU指定了高达2580MHz的Boost频率。然而，这只是一个建议，在实践中，我们观察到在我们的游戏测试中，时钟速度明显更高。在2,730至2,760兆赫时，KFA2GeForce RTX 4090 SG的AD102的运行速度大多高于指定的Boost速率。有了Xtreme Tuner，制造商提供了一个小工具来读取显卡的所有重要数值。例如，它允许你控制照明或调整风扇曲线。我们在测试中没有改变任何预定义的值。然而，在KFA2模型中经常使用的1 Click OC功能，与其说是真正的好处，不如说是一种幻觉。在实践中，GPU时钟速度仅增加15MHz并没有什么不同。我们希望这个功能能带来更明显的改善。

合成基准

在合成测试中，我们观察到的性能几乎与以下两者相同帕利特GeForce RTX 4090 GameRock OC但我们的测试装置仍然略微落后于帕利特显卡。从主观上讲，这两种型号提供了相同的速度。直接与Nvidia RTX 4090相比，性能的提升是 NvidiaGeForce RTX 3090是非常大的（90分，而不是57分）。同时，Nvidia Titan RTX的表现也相当不错。继Quadro系列之后，由于驱动程序的优化，该显卡在这里的渲染测试中能够取得明显更好的性能。

与AMD相比，KFA2GeForce RTX 4090 SG也轻松领先。与蓝宝石AMD Radeon RX 6950 XT的比较显示出平均53%的性能优势。然而，随着AMD Radeon RX 7900 XTX的出现，继任者已然在望。到12月中旬，它应该就在这里，红绿阵营之间的下一场战斗可以开始了。

游戏基准

KFA2GeForce RTX 4090 SG能够将合成基准测试中的高性能也转化为非常高的游戏性能。当它没有受到CPU的限制时，与Nvidia RTX 3090相比，其性能提高了80%以上。 NvidiaGeForce RTX 3090是可能的。在过去，我们只是很少看到两个GPU架构之间有如此高的性能提升。KFA2和帕利特又是眼见为实，我们无法看到两款机型之间有任何明显的差异。

RTX 4000的特殊功能，如DLSS 3.0，包括帧生成（FG），确保在许多游戏中获得额外的提升。作为一个例子，我们可以提到赛博朋克2077。在原生4K分辨率和Raytracing Ultra预设下，即使是KFA2GeForce RTX 4090 SG也只能达到平均44 FPS。但在激活DLSS后，超过100 FPS就不再是问题了。通过这一点，Nvidia提供了一个伟大的功能，在不久的将来，这可能真的会对购买决定产生影响。另一方面，通过FSR，AMD也有一个类似的功能正在开发中。因此，最终取决于游戏制造商，以及他们是否在其游戏中整合这些功能。你可以在这里找到已经支持DLSS 3.0或计划在未来这样做的游戏列表https://www.nvidia.com/en-us/geforce/news/dlss3-supports-over-35-games-apps/.

KFA2GeForce RTX 4090 SG的排放情况

与其他GeForce RTX-4090型号相比，KFA2GeForce RTX 4090 SG的功耗也不例外。450瓦的标准功率限制与其他RTX-4090型号一样高。然而，在可选功率目标方面，各种型号之间存在一些偏差。通过额外的13%，你可以将KFA2GeForce RTX 4090 SG的功率极限提高到约510瓦。Nvidia的创始者版甚至允许达到600瓦，而PalitGeForce RTX 4090 GameRock OC只有500瓦。但在实践中，这并不发挥主要作用，因为只有在最罕见的情况下，才会达到450瓦的功率限制。FurMark压力测试中的消耗量略高于370瓦。当时，GPU的温度保持在65°C（145°F）的低温，而风扇转速只有每分钟1300转。在39 dB(A)下，显卡的声音很安静。

KFA2GeForce RTX 4090 SG使用一个巨大的散热器，带有三个102毫米（约4英寸）的大型轴流风扇。作为选择，你也可以在背面安装一个额外的102毫米的风扇。然而，你必须确保与所使用的主板的兼容性。在我们的案例中，我们无法安装额外的风扇，因为Gigabyte X670E Aorus Master的内存库阻止了这一点。

如果我们将其与整个测试系统的功耗相比较，游戏时的功耗约为546瓦特。这只比与NvidiaGeForce RTX 3090 Founders Edition相比略高。同时，我们仍然测量到性能的大幅提高，因此GeForce RTX 4090在每瓦特性能方面领先一大步。我们还为我们的测试系统测量了一些高达700瓦的消耗峰值。 KFA2规定，GeForce RTX 4090 SG的电源容量至少为850瓦。另一方面，其他一些制造商则指定至少1000瓦，在我们看来，这有点太高了。

在12VHPWR连接方面，我们想在此指出，你必须确保插头完全正确地坐落在连接器中。但到目前为止，我们测试的任何RTX-4090型号在这方面都没有问题。

- 没有DisplayPort 2.1

- 极其昂贵

结论 - 极其强大、安静和凉爽

那些正在寻找最快的显卡的人目前不会绕过NvidiaGeForce RTX 4090。只有在很少的情况下，我们才能发现连续两代产品之间有如此大的性能跳跃。Nvidia还将功耗增加了100瓦，这相当于到目前为止的顶级型号，即 NvidiaGeForce RTX 3090 Ti.然而，我们只是很少遇到GPU的最大值450瓦，这也意味着GeForce RTX 4090目前在所有的游戏中都没有得到充分的使用。KFA2GeForce RTX 4090 SG在这里也不例外，它的性能与我们经常使用的测试装置，即 PalitGeForce RTX 4090 GameRock OC.由于非常大的散热器和三个大风扇，温度始终保持在绿色范围内。像RGB这样的噱头也包括在内，可以使用内部软件轻松控制。风扇也是如此，在2D操作或低负载下甚至保持关闭。

KFA2GeForce RTX 4090 SG是一款非常好的显卡，整个游戏性能非常高，令人印象深刻。一个非常大的散热器，多达四个风扇，以及大量的RGB照明吸引了KFA2模型的注意。

与帕利特的竞争对手相比，一些线圈的啸叫声有点过于明显，而且在主观上更容易听到。然而，我们仍然不会说这是令人讨厌的。虽然你可以对使用的12VHPWR连接有不同的意见，但到目前为止，我们没有遇到任何问题。12VHPWR连接的位置并不理想，因为这个大的适配器，不应该直接弯曲在显卡旁边，在很多情况下会造成一些空间问题。

RTX 4090目前没有任何直接的竞争对手，现在只剩下不同的制造商之间的竞争。根据他们自己的公告，KFA2与华硕的Strix型号和微星的Suprim X型号竞争。如果你看一下直接的性能数据，在性能技术方面，这里没有明显的优势。这意味着，目前，制造商只能以性能、视觉效果和价格的程度吸引一些注意力。AMD目前无法跟上其顶级型号，我们必须耐心等待，直到AMD Radeon RX 7900 XTX的出现。

价格和可用性

目前显卡的供应没有问题（在德国），即使价格与Nvidia指定的建议零售价（1949欧元，约2018美元）相比要高得多。例如，KFA2GeForce RTX 4090 SG目前在亚马逊（在德国）的售价为2749欧元。它在美国似乎更难找到：虽然它在亚马逊没有上市，而且Ebay显示它 "售罄"，但一家在线折扣店显示它以1400美元出售。它似乎在一些市场上以 "Galax "品牌出售。
