I suppose you're right 3Dude. I just didn't want to admit the system would be fast with slow memory. I've seen the difference memory bandwidth makes on computer graphics cards, which of course don't have edram, just cache.
To the "why are you freaking out over this?" statement.
Fast? Yeah, depends on who uses it. Nintendo has always had an old school design mentality. The same kind of Mentality that is shared by devs like Shinen, and the old pc jedi's like future shop.
Kids who have been raised on limitless memory and Ghz power, have never had any experience managing anything, as all machines they have been used has been so powerful it just chugs through their horribly sloppy code. Cant do that with Nintendo systems. You could never do that with Nintendo systems. No matter how much incompetent spoiled dev kids whine, this has never, and will never, be anything but a good thing, until the day the singularity is upon us, and man and machine are one.
Go through Iwatas asks about the wii u, and dev interviews by named well known devs like shin en, and see what they have to say about memory, and specifically, Memory heiarchy.
Memory heiarchy means that slow main ram is the bottom of a totem poll, of a heiarchy ram system.
"I would draw attention to how efficient it is. For a computer to function efficiently, memory hierarchy
20 structure is very important, and this time the basic memory hierarchy is tightly designed. Although that is an orthodox solution, it makes the foremost feature of this machine's high efficiency."
'20. Memory hierarchy: Structuring computer memory in layers. The human brain has short-term memory for remembering information related to a certain matter currently in progress and long-term memory for long-term storage of information unrelated to immediate circumstances. Likewise, a computer transfers and manages data by layering storage, with the CPU at the top, high-speed low-capacity cache memory serving as short-term memory underneath, followed by low-speed large capacity main storage for managing hardware, and auxiliary storage for managing the OS on the bottom.'
http://iwataasks.nin...iiu/console/0/3I mean guys, this is like, a month old, more even, He even flat out calls the main memory 'Low speed large capacity'. This was never a dirty secret. Its not a surprise, a system teardown was not required for this information, its right there in the iwata asks, low speed large capacity ram.
What do named devs think who have experience with memory managemnet? Well, chec out not enough shaders Shin en mega interview.
More specifically, we’ve heard rumors about the CPU, that it’s supposedly the weakest link of the system. Word has spread that it’s some sort of Broadway (Wii CPU) but in a three-core configuration and improved. Others have argued that based on its reduced size seen in recent pictures and the overall low consumption of the unit, it is not very powerful. Have you encountered any problems during your development because of this component or is it efficient enough?We didn’t have such problems. The CPU and GPU are a good match. As said before,
today’s hardware has bottlenecks with memory throughput when you don’t care about your coding style and data layout. This is true for any hardware and can’t be only cured by throwing more megahertz and cores on it. Fortunately Nintendo made very wise choices for cache layout, ram latency and ram size to work against these pitfalls. Also Nintendo took care that other components like the Wii U GamePad screen streaming, or the built-in camera don’t put a burden on the CPU or GPU.
