In terms of speed, the R7 7800X3D has the advantage (over the R7 5800X3D) of a higher IPC (according to selected AMD internal tests by an average of 13%<\/a>) and also higher all-core boost clock speeds, depending on the load by 300\u2013400 MHz<\/a>. Single-core boost<\/a> is also faster, increasing application performance across generations in tasks that use only a single thread. But the Ryzen 7 7800X3D still lags well behind models with “regular” L3 cache in this regard. This is because the technology used to connect the chiplet with the 3D V-cache cannot handle as high a voltage as could be used in the rest of the chiplet.<\/p>\n A greater, tighter maximum voltage limit naturally means lower clock speeds<\/a>, but these are still higher than with the Ryzen 7 5800X3D at all levels, which also means higher bandwidth and lower L3 (but also L1 and L2) cache latencies<\/a>, the benefits of which are mainly discussed around gaming. These access a large amount of data from RAM, for which the CPU waits longer than from the L3 cache, which usually cannot hold everything necessary though. In the case of Ryzen processors with 3D V-cache, the situation is better, the cache capacity is significantly larger.<\/p>\n If such a large cache is well implemented, the negative impact of lower clock speeds can be outweighed and ultimately higher gaming performance can be achieved. That’s why this processor is associated with the word “gaming” \u2013 it should have the upper hand in such an environment. And not just in terms of speed, but also in terms of efficiency, which was already a cut above with the Ryzen 7 5800X3D<\/a>. With the Ryzen 7 7800X3D, the gaming performance per watt ratio is pushed to a higher level by both a more efficient manufacturing node \u2013 5 nm (Zen 4\/R7 7800X3D) vs. 7 nm (Zen 3\/ R7 5800X3D), and the fact that AMD set more efficient clock speeds, which was kind of unavoidable as well.<\/p>\n The Ryzen 7000s, including the R7 7800X3D, have a slightly smaller CCD chiplet area with a higher heat flux density. Combined with the poorer heat conduction properties of AMD Raphael<\/a> processors’ IHS compared to older AM4 models, and the generally worse heat dissipation of X3D processors (through the extra cachce layer), a more powerful cooler is then needed at the same power draw to achieve the same temperature. <\/p>\n However, to make do with what you already have or to avoid having to buy very expensive coolers, AMD has significantly reduced power draw. So why is there a TDP increase stated in the parameters \u2013 120 W (R7 7800X3D) instead of 105 W, which has a higher power draw?<\/p>\n![\"\"](\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2023\/07\/amd-ryzen-7-7800x3d_01-1024x513.jpg\")
