<p>right im going to start this thread with some factual benchmarking and results and numbers to lets say balance peoples minds.. no links im on a mobile device but simple web searching proves all of this following post FACTUAL...<br />
<br />
expresso is the highest clocked 4 stage pipeline cpu in existence !!!!<br />
<br />
x360s cpu was 40 stage pipes long LONGEST IN HISTORY EVEN LONGER THAN INTELS WORST EVER CORE P4 PRESCOTTE<br />
<br />
wiiu cpu stagepipes are 10 x shorter than x360 cpu<br />
<br />
jaguar cpu pipeline stages are 16 stages long 4x longer than expresso....<br />
<br />
vs ATOM at the same clock speed bobcat was slightly more powerful than a ATOM and jaguar bobcats replacment was slightly more powerful again AT THE SAME CLOCK SPEED<br />
<br />
jaguar cores are a SLIGHTLY better clock for clock cpu core than bobcat and ATOM<br />
<br />
powerpc 750cl a cpu around the same spec as broadway in wii beat the living day lights out of ATOM at half the clockspeed FACT go check powerpc750 cl utterly desimated ATOM cpu core at 1600mhz a powerpc 750 cl at 800mhz ish utterly destroyed ATOM in benchmarks...<br />
<br />
in fact in the last gen era powerpc 750cl was the most powerful 32 bit cpu core ON THE PLANET no other core came close non of intels or AMDs or ARMs it was the fadtest 32 bit risc core avalable...<br />
<br />
jaguar cores stronger than expresso cores LOL ALL RIGHTY THEN KEEP DREAMING...<br />
<br />
atom then bobcat then jaguar in order of lowest to highest performer @ THE EXACT SAME CLOCKSPEED 1600mhz<br />
<br />
reminder powerpc 750cl beat ATOM @ 800mhz with EASE go check out powerpc cl benchmarks i think you will find ZERO BS in this post...<br />
<br />
expresso is tri core and 1240mhz and has EDRAM level 2 catch not sram so bandwidth is easily doubled or more vs sram catch its also the first cpu in history to do this<br />
<br />
its risc ,its power ibm,it has graphics data burst pipes per core it has peak 4to1 data compression it has the shortes pipeline stages of any pc,tablet,console out there 4 x shorter than jaguar..<br />
<br />
jaguars benchmarks are WEAK AS revel in the beautiful sunshine vs ATOM yet BROADWAYS EFFECTIVLY PPC CL utterly desimated ATOM AT HALF THE CLOCK SPEED<br />
<br />
expresso cores eat powerpc cl for breakfast there clearly VASTLY BETTER THAN JAGUAR LOL CORES...simple research proves this???<br />
<br />
expresso has 4 x shorter pipes than jaguar<br />
<br />
expresso has peak 4to1 data compression<br />
<br />
expresso has access to gpu's edram<br />
<br />
expresso has a single core with 2mb catch jaguar shares that much catch between 4 cores<br />
<br />
wiiu MCM IS LOW LATENCY<br />
<br />
AMD APU's are HIGH LATENCY (VERY HIGH)<br />
<br />
broadway cpu of wii @ a lowly 729mhz was infact only slightly of a x360 core @ 3.2ghz in benchmarks it was almost on par in all benchmarks ????<br />
<br />
facts are facts they cannot be argued,,broadway cpu at 729mhz kicked ATOM ass @1600mhz and almost matched a x360 cpu core @3.2ghz<br />
<br />
jaguar cores do not come close to this figure they do beat ATOM AND BOBCAT BUT ONLY BY 20% OR SOMETHING<br />
<br />
that is far far far lower than the per core benchmarks of powerpc 750cl and broadway FACT BENCHMARKS PROVE THIS...<br />
<br />
wiiu ram latency is 10x ps4s as in 10x faster wiiu cpu has 10x faster access to memory than ps4 plus wiiu cpu has direct access to gpu EDRAM that is catch like speed at least 20x the speed of ps4<br />
<br />
edram sub 5 ns ddr3 20ns and remember wiiu has optermized pre fetch and massive mulipul catches to gpu<br />
<br />
weak cpu LOL DIGITAL FOUNDRY GOT YOU TIED UP WITH BULL rainbow<br />
<br />
JAGUARS ARE FREAKING WEAK TOTALLY LACK DATA COMPRESSION TOTALLY LACK GRAPHICS BURST PIPELINES AND HAVE PIPELINES 4X LONGER THAN EXPRESSO<br />
<br />
AND THE APU's there part of are VERY HIGH LATENCY...<br />
<br />
wiius mcm is many many times lower latency than the AMD SOC FACT<br />
<br />
IBM POWRR MCM BUILT FROM SCRATCH FOR GAMING PERFORMANCE AND LOW LATENCY<br />
VS<br />
OFF THE SHELF AMD APU's that have terrible latency and crippled memory set ups LOL<br />
<br />
ps4 is a high latency poor gpu to memory device with bottlenecks all over the place and a funky memory system with 200ns ram lol<br />
<br />
<br />
please explain this how is jaguar stronger it clearly isnt at all there clearly vs ATOM a slight upgrade yet powerpc cl at half the clockspeed a core closly related to expresso UTTERLY DESTROY THOSE BENCHMARKS<br />
<br />
custom cpu vs low end amd tablet cpu THIS ISNT MISSION TO MARS ITS BASIC COMMONSENSE ???</p>

Lol, seems like the site replaced all your "enter"s with <br />

 

I blame it on the fact that you were on your phone. Must've messed the site up or something.

I am no Techno Genius, that is for sure, but it seems like you are saying that the Wii U blows away the Xbox 360 and with that I would assume it does the same to the PS3,   But where do you stand with regard to how it stands against the PS4 & Xbox One?  Please put it down in simple terms if you can .... like blank X less powerful than the PS4 / Xbox One.

* espresso
* cache

Provide some solid links/evidence, and present the information in a more composed/less obnoxious manner. Regaurdless how much of the information is true, people are going to have an aversion to it if its presented like.... That.


Heres an amd comparison diagram between bobcat and jaguar.


AMD-Jaguar-vs-Bobcat.jpg

Its about 30% better performance per core than bobcat, with things like improved cache (still less per core than espresso) and increased clock speed.

In general processing, Nintendos custom tricore 750 and its crazy cpu caches will most certainly out perform jaguar clock for clock, thread for thread , core for core.

However, Jaguar has focused on an aspect bobcat and espresso havent.

AMD Jaguar supports all current
SIMD instruction sets including SSE 4.1, SSE 4.2,
AES, CLMUL, MOVBE, AVX, XSAVE, XSAVEOPT,
FC16 and BMI.

Espresso supports literally NONE of these, it demands devs learn nintendos proprietary paired singles simd.

Jaguar doubled its floating point pipelines over bobcat, the chip will
come with 128-bit FPU pipelines capable of
executing 128-bit FPU operations in one clock
cycle. This is one of the best floating point solutions you will find in the mobile chip market (although core for core, it still a far, far cry from 360 and especially ps3 cpu flops).

Espresso retains the same 64 bit simd pipeline as wii and cube. Just x3 since there are 3 cores. Nintendo clearly doesnt care much for prioritizing cpu simd/flops. Paired singles have been benchmarked (broadway tested at espressos clock speed) and have been found to keep up surprisingly well.... Not being far behind bobcat at all. (pretty damn good for a simd architecture left unchanged since the late 90's) however, jaguar heavily focused on this, and clearly has an advantadge. Nintendo is clearly more interested in more powerful single thread process performance for their cpu's. Being that the cpu can access the gpu's edram very quickly, its likely Nintendo intends to use the gpu for any simd beyond what three 64 bit pipelines can handle.

So yeah, espresso stands up very well core for core clock for clock to a stock jaguar a mobile processor, it comes out on top in some areas, and falls behind in others.

The problem is there are over twice as many jaguar cores in xbone/ps4 cpu's than in espresso.

Just because I'm curious. What would Wii U being doing if i had 8 espresso cores clocked at same speed

people comparing the WiiU to the X360 & PS3 are idiots.

It would be more powerful in many areas than the jaguar in xbone/ps4.

It would still be considerably behind in simd.

Ill just consider ps4/x1/wiiu cpu's about even until we see strong evidence in well developed games.
