Does Ryzen 7 feature infinity fabric?

All Ryzen chips use it, even 4 core CPUs. It connects the CCX modules in all of them (Ryzen 3 CPUs should have 2 CCX with 2 cores each). EPYC also uses Infinity Fabric for communication between multiple CPUs in dual socket setups, I think. So, yes, all of the Zen based CPUs have it.

On topic, 7820X actually looks a lot better than 7900X, to the point where I'm sort of tempted by it. It's a shame that Intel's previous prices were so high that they still can't bring such new products down to Ryzen level pricing. Nor, I suppose, would they want to. I still don't like the platform either.

Platform costs are a real kicker for Intel. I don't know how much of it is down to a genuine cost of the chipset manufacturing, artificial cost of the chipsets to the board makers, or a premium added by the board makers. When Intel was the only way to get top end performance then the premium price for a motherboard could be justified that way, but doubling the cost of a motherboard for comparable system performance isn't going to win many customers.

If AMD have opened up the HEDT market to more consumers through their competition then we'll presumably find out - competition between board makers should minimise their margins if they want to attract the previously priced out market. Whereas costs from Intel will just sit there until they feel they need to lower total platform cost (which I think they will struggle to justify while the same motherboard can be used for an i9 as well as lowerish end i7 Xs.)

.....I am still waiting for AMD to make GPUs for smartphones and tablets, any plans on that field?

Nope,since even Nvidia left that area.

Hi there,

Prices tend to change quite quickly, so levelling the playing field the best we can, we look at the official pricing from both companies. AMD says that it has instigated no price-drop on the Ryzen 7 1800X, and that it is retailers who have chosen to reduce cost, but I see your point.

Appreciate it is more work, I dont know if a better solution is compare the top retailers and give an approx price at the time of review? I dont know the answer just in this scenario the price difference is quite high so makes a significant impact on deciding a platform (at least it would to me if I was buying a new one).

Good review as always though!

Maybe Hexus can state the RRP and current "street price" on the day of the review. If the "street price" is significantly lower it can be mentioned in the article,at RRP XYZ maybe true but in reality its cheaper so ABC is now true.

Like the days on eBay where postage wasn't considered for the seller fees.
Price of the CPU is almost irrelevant with such a vast difference in platform entry cost. This is still a pretty poor value option IMO. Intel needs to do much better.

Agreed with the above comments. Review websites need to provide a better and more objective info about value, that means comparing the total cost of a CPU, Mobo and CPU cooler.

So you pick the same range mobo, same range cpu cooler and compare the overall cost. They don't do that because it shows Intel in an extremely negative light. They can dust off the $180 price difference between the 7820x and 1800x, kind of avoid the elephant in the room that is the 1700x and costing $600 vs the $330 1700x, but in terms of overall cost the Intel platform costs anywhere from the cheapest of $850 to an average of $950.

AMD platform with a 8 core processor Ryzen 1700, b350 board and no need to buy a cooler costs as cheap as $380, on average $400, that is less than HALF the cost of the Intel 8 core platform!

How is the value better? If anything the value is worse, much worse, since the new platform overall would cost anywhere from $850 up to $1000.

Again we are looking at $600MSRP, street prices are closer to $670, decent mobos are $200+ usually $300 actually, and looking at a good cooler is another $100. So 670+250+100=1020. So you are paying $1020 for 8 cores VS Ryzen 1700($300), AM4 B350 mobo($100)=$400. So you get 8 cores for $400 from AMD, no need to buy cooler with the 1700 and it can OC on stock cooler up to 4.0GHz stable on all cores.

You can use the additional $400 to $600 you have left to buy a brand new 1080TI.

is this cpu good for gaming and streaming as i am going to be building gaming pc for streaming ? thank you

You don't need an i9 for that.

EDIT: Oops wrong part. You don't need 8c/16t for that.
