Judge Allows Lawsuit Over AMD's FX Processors to Continue



I mean technically they are 8 core CPUs. They just share resources which make them slower than other 8 core CPUs in some tasks.

However what needs to be defined is the "core". What constitutes a core? They keep changing. Cores used to be the more basic part with L2 cache being an add-on part you could buy. After a while the L2 cache was integrated into the core and thus became part of the core and ever since most CPUs have separate L1 and L2 cache per core.

So I guess what will really happen is they will have to define what makes up a core and if it fits then its thrown out. If it doesn't I could see AMD losing the case. I really think AMD should have just called it something like Advanced Hyperthreading as the reality is that is what it was.

If the lawsuit goes thru with a loss for AMD. I IS SEE OTHERS putting a claim in. I think this is another way to either have AMD loose money, or the guy who decided to do the lawsuit is either a stock holder upset over his stock, since the release of Ryzen, or its another INTEL Athlon day ploy HE WAS PUT UP TO.

The bulldozer design was stated before it was on sale, it was a tech site saying it was not 8 cores base on how INTEL CPU cores was design. So Whatever new design comes out is always a disputed because its not like it has been before, Are you saying a white man can dunk, because he is not black man. this is the same with this lawsuit, AMD bulldozer is not a 8 core because it does not have the design specs of a Intel CPU. The guy who bought the processor could not afford the EXPENSIVE multi core INTEL CPU and motherboards AT THAT TIME and AMD offered him a alternative.Now seeing AMD making money and gaining on INTEL in market share,he decides to slow AMD up by the lawsuit,if he wins this will open up others to sue AMD OR PUT A CLAIM IN, causing a cash flow minus plus possible stock drop. If he is that stupid when it came to buying tech, he should have done his homework. This type of info was on the net, either he is a crazy INTEL STOCK HOLDER upset how the stock has gone since the release of Ryzen or someone is pulling this guys strings to do this.
Please remember what INTEL pulled with the computer makers back in the Athlon days, COULD THIS BE ANOTHER WAY without violating the laws in place right now
for fair business practices

Yeah... I don`t have buldoser and even I know how bulldoser cores does work. It is 8 core and it is not. Just based on how you define core. And amd did tell how those ”8” cores work and were made so no shady game in there!

They did not mislead. I run chess games and all the cores ran chess games just fine. 8 games, all as fast. These were not hyperthreads.

The media looks at the architecture and says 4, but that does not mater.

Did the chip live up to expectations? No not really. But that is true for a million products out there.

Bulldozer CPUs were designed for server first and foremost. They were designed to be more powerful at integer workloads because that's where they believed the focus should be. Each module has two integer units with four pipelines. Given that a module generally offers 50% more performance than a conventional core, this along with the duplication in integer processing resources should be enough to differentiate itself from Intel's Hyperthreading. The only real sticking point (for me) could be the inability of the integer units to be fed at the same time (something that was changed for Steamroller).

If the complaint is about any of the shared parts, AMD were clear about those from the start.

I hate lawyers since there is no true legal definition that I am aware of that defines what a core is since there are 8 quasi-cores or whatever you want to call it I can't see them winning this one. Any technical person that looked at the literature of the time I think could clearly see how it was designed and its not like they were hiding how the architecture was organized to "fool" people.... it is a dumb lawsuit and I hope it goes away with extreme prejudice.

If any of the cores were cores, then they all were, as they performed the same. There were not 2 classes of threads.
The media could have gone the other way and called it a 10 core with those 128 bit units.
They just wanted some way to put down this chip, because it could not match Intel.

It's a class action lawsuit, so if they lost and were forced to pay out it would go to all potential plaintiffs. You couldn't just go and sue them again for the same thing afterward.

The bulldozer design was stated before it was on sale, it was a tech site saying it was not 8 cores base on how INTEL CPU cores was design. So Whatever new design comes out is always a disputed because its not like it has been before, AMD bulldozer is not a 8 core because it does not have the design specs of a Intel CPU.
It's not just Intel CPUs that were different. Earlier AMD CPUs were designed the same way, until Bulldozer came along with its "clustered multithreading' and associated shared resources between two cores in a module.

Not saying that makes the Intel/old AMD approach the official definition of a core, but it's wrong to say that this issue is just a matter of 'Intel core design' vs 'AMD core design'.

I can't see them losing, and all this judge has said is it's not being thrown out... yet.

It's not like the inner-working were a trade secret. The marketing didn't fit the product accurately, but it's not like they purposely concealed the true nature of the shared resources.... That's what I think it'll boil down to.

However, if they were to lose, it's their own fault.
With no legal definition of a "core", it's likely to fall onto industry standard acceptance.
Prior to FX, there was never any ambiguity in marketing regarding core count. Even when HT was new, there were rumors/misunderstandings in the space about being double the "cores", but both Intel & AMD never marketed as such.
FX is where AMD decided to change the accepted definition to meet their marketing plans for an "8c" CPU.

I don't think a loss would be beneficial for the industry, all it would do is deplete AMDs current bank balance.
They're not typically in it to maximize profits, but want market share. If their hand was forced through payouts, they may need to increase the profit margin on new products to cover it.

I own a FX 4350, 6300 and 8350 (they are stupid cheap right now) just to see the difference. I also own a core i5 2400 and core I7 4770k, the 6300 preforms about like the i5 2400 and the 8350 has roughly 80 to 85% the performance of the 4770k. I will say though they are excellent overclockers, but are super weak single threaded. I think they are full of crap saying the 8350 is an 'eight core' cpu, its a 4 core 8 threaded cpu that almost has the performance of an i7. I own a couple of ryzens, they are good cpus, especially for the money but they arent intels, i have the benchmarks to prove it. AMD just knew people would want to brag about an 8 core so thus creating the 8350, but with that logic the i7 4770k or 2770k are 8 core cpus too, right??? curious to see how this ends up.

I have several FX processors, and I was led to believe they were 8 cores. and yes i still feel they are sluggish , but do get the job done. I dont know what will happen but I think that AMD should have come clean, I always bought AMD for price/performance but i will be pissed if it turns out that this was a farce
 


So by explaining how their CPU works, they mislead the customers?

By the same logic, Tensor cores, Graphic cores... are not cores, because they are not Intel cores.

It is called CPU design. AMD FX design work this way, but they do have 8 cores... if you look on the silicon, they do have 8 cores, so it is 8 cores.

Only in the US, lawsuits are a national sport.

This is specifically about x86 CPU cores. So yes, in that context those two things would not be cores.

I still use my FX-8350. 32 gigs ram, dual radeon 7870s. Buzzard still holds its own. Runs on par against an i5-3570k oc'd to 4 ghz, with an Nvidia gtx 1050. I have no complaints.
 


They did explain how their CPU works and they are 8 cores.

However, cores, are not exclusive to x86, and their analysis is based on different designs than AMD. You see, it is your interpretation while I am basing my analysis on the fact that they are physical.

These core are on silicon, making this a joke. AMD made those processing decisions because the cores share some component on the chip.

It is a stretch to say that these chips are not 8 cores because some of them share processes. The only thing AMD needs to do is share the damn picture and explain to the judge these core exists by making a demo.

It is so stupid, even an old Cinebench is showing the 8 Core variant having nice scalable score of 90% over the 4 core FX 4100. The 6 cores FX100 is 50% faster than the 4 cores iteration... how can this be if they are only 4 cores.
