AMD 第 6 代 EPYC Venice：发现 CCD 配置和线程性能
功耗是另一块拼图。SP7版本（Zen6）的功耗约为 600 W，高于基于Zen5的Turin系列的40 W。这个颠簸是更高时钟的权衡。同时，SP8（Zen 6C）CPU在 350–400W 范围内运行温度较低，即使内核数量更高。这是一个快速的阵容比较，以正确看待它：
-
EPYC Venice Zen 6C：256个内核，512个线程，8个CCD，每个CCD 128MB L3,350–400W TDP
-
EPYC Turin Zen 5C：192个内核，384个线程，12个CCD，每个CCD 64MB L3,400W TDP
-
EPYC Venice Zen 6：96个内核，192个线程，8个CCD，每个CCD 48MB L3,600W TDP
-
EPYC Turin Zen 5：96个内核，192个线程，16个CCD，每个CCD 24MB L3,400W TDP
Zen 6C提供最高的内核密度和每内核缓存，而Zen6以更高的功耗为代价提供更高的频率潜力。根据您的特定计算任务（无论是单线程性能还是大型多线程工作负载），选择合适的 Venice SKU 将帮助您优化每瓦性能和总吞吐量
