In that case, the 4/6/8 core models should all perform similarly, except that the 8-core CPU has twice the cache of the 6-core and 2.5X the cache of the 4-core, so it might be expected to outperform on some tasks (and it won’t matter for many). Speeds noted here might be off slightly and can be subject to thermal load which exceed TDP (thermal design power), which will reduce clock speed from top rating. If the power, current, or thermal limit is reached, the processor will automatically reduce the frequency to stay with its TDP limit. Īny of these factors can affect the maximum frequency for a given workload. The number of cores operating in the C0 state.To determine the highest performance frequency amongst active cores, the processor takes the following into consideration: To take advantage of the available TDP headroom, the active cores can increase their operating frequency. Therefore most applications are consuming less than the TDP at the rated frequency. However, under typical operation, not all cores are active. The processor’s rated frequency assumes that all execution cores are running an application at the thermal design power (TDP).

This does not take the inevitable multi-core overhead into account (hardware and software factor), which degrades performance as the number of CPU cores increases. ± Taking clock speed into account, the equivalent number of 3.7 GHz CPU cores (multiplier of # of cores times the clock speed). ** Core-Friendly = Estimated real-world best-case performance taking into account clock speed and CPU cores, application multi-threading efficiency, memory contention. * Ordinary Task Speed = expected speed with mainstream tasks which typically use four CPU cores or fewer and rarely more except for brief spikes. And it’s a good middle ground for workflows which mix video with other tasks.Īppropriate mainly for video users, but other workflows can benefit if the tasks use all cores frequently.
With a 14% drop in clock speed, the 8-core model is not likely to outperform the 6-core model for most tasks, but it has more cache memory and this might mitigate the clock speed losses. CPU Coresįastest for general use due to highest clock speed, but many operations in programs like Adobe Photoshop Lightroom or Photoshop will be slower than with 6-core or 8-core options-and others will be faster! It all depends.Ībout 5% slower than the 4-core in clock speed, but the two extra CPU cores are WELL worth it for programs like Adobe Photoshop Lightroom. The 12-core models is aimed at video processing, or specialty tasks where all cores are fully utilized, and are best paired with the fastest GPUs for those who really do intensive video work. However (see discussion that follows), Turbo Boost mitigates that initial assumption and if the workflow involves more cores, those extra cores can pay off. Given the reduction in CPU clock speed, the 8-core CPU appears at first glance less attractive for all-around use than the 6-core model, and the 12-core model is even less attractive. Programs like Adobe Photoshop Lightroom and Photoshop make use of 6 - 8 cores better than ever in the latest 2014 "CC" versions. Those with the most demanding needs might opt for a CPU upgrade.įor many users, 6 CPU cores is the sweet spot in offering the best price/performance along with the next faster GPU speed.

The 6-core model up-configures to 16GB memory and dual AMD FirePro D500 GPUS.Base 4-core model comes with 12GB and dual AMD FirePro D300 GPUs.
