Wow, looks like they are still sticking with 2MB of cache. Very disappointing if true.
Lower manufacturing costs, to make Zen cheaper to most consumers.
Bristol Ridge isn't Zen, it's Excavator for the desktop. The reason it is relevant is that it's launching the socket that will be used by Zen. As Bristol Ridge is essentially the same silicon as Carrizo, the 2MB L2 cache is a known entity. From what we've seen from Carrizo, these chips will be a reasonable step up from Kaveri, but still no where near anything Intel is selling in most cases.
I don't have a problem with either PGA or LGA myself. The PGA used in mobile parts look like they could bend if you so much as look at them funny, but those are no problem either.I think it's just another angle to pick on something. After over 40 years of computer repairs and upgrades, I've discovered that if you're sober and pay attention then things don't get bent.
Haven't you seen reviews?Overall you're right, but some folks are convinced it's gonna hurt game performance.
The problem is actually that the L1 is awfully designed. L1 is write-through, so L2 write throughput limits L1 throughput. L2 throughput is limited by number of possible parallel accesses and by latency, so reducing L2 latency improves L1 throughput.
So you are willing to buy a system for future upgrade without knowing how a future CPU will perform? D:
The news of yesterday was an April's Fool, and at the present moment is not a secret anymore. The AIDA64 screens were fakes, but there is a kernel of truth.
First of all, A0 samples of 8 cores Zen exist, and it seems that AMD has already delivered them to its partners for the preliminary tests. The base frequency seems to be very high (3 GHz, Turbo still not enable with these ES) for a high end 8 cores CPU, also produced on a new node like the 14nm LPP FinFET of Samsung/GloFo (The first ES of Bulldozer worked at 2,8 GHz). It is a promising start.
About Zen, I can tell you some my speculations (NO OFFICIAL INFO) and some news from USA (from the same guy who told me about Zen, 3 days earlier the Official Presentation made by AMD).
If 14nm LPP will be good, Zen base frequency (8 cores version, TDP 95W) will be 3.7-3.8 GHz. Turbo 4.1-4.2 GHz. If 14nm LPP will be very good (or if AMD will commercialize a limited edition, like the Athlon Slot A 1GHz during the good old times), Zen will have a base frequency of 4 GHz (Turbo 4.2-4.3 GHz). Also, the overclockers will have a lot of fun, because of the soldered IHS!
Zen seems to be a High Performance and High Frequency uArch, like Skylake and Kaby Lake, but with some little tweak. The design team lead by Keller, as you know, has chosen to simplify some features in order to limit the Power Consumption and improve the Frequency, due to the low availability of appropriate software at the present moment (e.g. 2 x 128 Bit FMA instead of one big 256 Bit FMA SIMD). FPU units, however, will be very strong. In theory, Zen will be a monster in video games tasks (It's just an example). We can expect an IPC at Broadwell level. And if some companies want some features, AMD can do a Custom Zen CPU/APU (It has a modular design).
Last, but not the least, the part of the news about Intel was true. It seems that Intel will commercialize a 10 cores Broadwell-E due to its own internal Zen simulations (Intel has some data we don't know, yet, and has skilled engineers that know what they do). Zen will have 8 cores, while Broadwell-E 10 cores. So, Intel will have the “King of the Hill”, but Zen seems to be very good in the mid range of the market (AKA, gaming and enthusiast configurations).
