Intel VS AMD

So you are on the hunt for a new computer and you are trying to decide on the components that you want to put together for you build. One of the first fundamental questions is what CPU to get?

This leads to an inevitable question of “should I buy ‘Intel’ or ‘AMD’. For the most part, unless you are looking at certain features or support, it does not matter. Low budget builds do not get influenced much in terms of the performance you would expect on thing like emailing and web browsing.

However at high-end or specific build considerations it can matter and there are some features that do give more bang for your buck.

PCIe 3.0  vs PCIe4.0

This is a little contentious at the moment, as current gen AIC do not use up all the bandwidth in PCIe 3.0 lanes. However there is a case scenario where 4.0 can give a larger performance increase. And that is in crossfire or SLI configurations. At the moment Intel CPU supports up to 16 PCIe lanes of consumer level CPUs. A single GPU utilises the maximum 16 lanes available. So when adding and additional GPU the bandwidth is split between the two devices. This can happen on other AIC cards as well. Such as a sound card which may use 1 PCIe Lane however if paired with the GPU, the GPU would be limited to 8 PCIe lanes to use.

The drop down to 8 lanes on a GPU can lead to bottlenecking as communication between the CPU and GPU becomes more congested.

With PCIE 4.0 the throughput is doubled per lane in comparison to PCIe 3.0. This can enable little more flexibility. As a dual PCIe 4.0 compatible GPU setup can still make use of the throughput each would enjoy if it was a single card utilising the full 16 PCIe 3.0 lanes.

PCIe lanes

A simpler consideration is the number of lanes made available by the CPU and how many can be used by AICs. As mentioned Intel has 16 PCIe 3.0 Lanes. Their competitor AMD, offers 24 Lanes. Simple Math, more lanes means more devices can be added without risking bottleneck any of the components added.

On an note, it is quite odd that Intel chose this route, as their product line up offers one unique feature. That is native support for their Optane SSD AICs.

Winner AMD

Core count

For multithreaded applications, the more cores you have the faster the computer can complete tasks that are assigned to it. Intel’s consumer level CPU the 10990K comes with a 10 core configuration. AMD offers 3 CPUs the 3900X and 3900XT which feature 12 cores and the 3950XT with a 16 core count.

Winner AMD

Cost

With the example of the 10990k from Intel, the RRP currently stands at $999 AUD it was released Q2/2020 while the AMD offerings are slightly older they have the 3900XT available at around the $850 mark and the 3900X around $100 less. These are serious value propositions. Especially considering that they out class the Intel counterpart at every key point.

Winner AMD

In the current market AMD has an edge in performance and value for money in the consumer market.

I offer no opinions; this is just a stats comparison to simply to help guide you to what you look for. this should also just be the beginning of your discussion into a CPU and which would be best for your needs.
