Business desktops and laptops have a long replacement cycle and often tied to multi-year procurement contracts. Businesses are also risk averse and so will go with what they know. For example UK public sector procurement frameworks are predominately Intel.
I can see AMD making gains in the server space as the Epyc chips are impressive and offer good VFM which corporate accountants will like. They recently achieved a 1% market share (for the first time in 4 years) so it is a steep hill to climb. Lisa herself has a personal goal of reaching 5% by the end of the year.
Funnily enough some of what you are saying is correct...
I work for a global manufacturing company with sites in every part of the world. My job role is client hardware, which includes procurement, distribution, upgrades, configs, rollouts etc etc.
We buy client hardware only from Dell, our server infrastructure again is all Dell, our network infrastructure is now all Cisco.
I spend a lot of time on the Dell Portal, and as yet I've not seen a Ryzen based laptop, desktop or HEDT Workstation. Our cycle on client hardware is 3 years, but the minute I see Dell add Ryzen to Latitudes and XPS systems I will swap our client machines across, I have had this discussion with other IT teams around the world and many are in agreement. The FC's want us to spend as little as possible so they will add pressure to make the swap if there is a decent cost saving towards opex.
My infrastructure colleague was at a Dell event today at Shepperton studio's, and it seems Dell was pushing Epyc hard, citing licensing savings due to the bigger core counts meaning less sockets overall etc.
Unfortunately as we are heavily VMware, and Intel based it would mean replacing everything at once as I believe Intel and AMD in the same VM environment do not play well together. And my boss doesn't want the hassle especially as we are a 24hr operation, just not an option right now.
But I was surprised to hear that Dell are really pushing Epyc at these events, which is nice to see, but I wish they would add more business client AMD options.
I bought a Xeon XPS workstation a couple of years ago for a CAD machine and the thing turned up with a 1080FE as the GPU lol... I questioned why there was no Firepro or Quaddro option at the time, just found it hilarious. That card has probably done all of 20hrs work in its lifetime lol.
But anyhow, there is definitely interest in AMD from a corporate business model, our central IT and the money men are all looking at it. Can imagine this is only going to increase as well.
