Hmmm....GX-420CA for a HTPC?

Edit: Just figured out those are embedded...Nevermind!

I wonder if that top QC part has any Turbo mode.

Jaguar is expected to be about 15% faster in IPC than Brazos 2.0, correct?

That's what AMD says, yes.

I've always assumed this was an average over all programs, meaning that it'd include some SIMD-heavy programs that get higher than a 15% due to moving from 64-bit to 128-bit units. As far as I can tell this applies to both the FPU (FADD + FMUL) as well as the integer (VALU0 + VALU1) SIMD units. That could bring down the average percentage to below 15% for programs that are more scalar, depending on what AMD's testing mix was like.

Those prices seem kinda high.

 

[Vesku]

Keep in mind they are SoCs where as previously the vendors had to also include a chipset. Won't get an idea of what the volume pricing is like until the consumer version all in one boards show up in retail.

 

[mrmt]

The embedded line up being launched together with the consumer line up?

That's what I call a shift in priorities.

 

[strata8]

Those prices seem kinda high.

Intel prices comparable embedded Atom processors between $54 - $85 so I don't think it's high for the market segment.

The Jaguar software optimization guide is very explicit about this, the whole FPU pipeline (also including Load/Store) has been widened to 128-bit.

Oh. Knowing AMDs marketing, you're probably right. So we'll be looking at 5-10% for integer.

The Jaguar software optimization guide is very explicit about this, the whole FPU pipeline (also including Load/Store) has been widened to 128-bit.

That's not what the "as far as I can" tell part was about, it was about whether or not Bobcat had 2x128-bit integer SIMD in the first place. For comparison, Cortex-A8 and Cortex-A9 have a NEON unit with 128-bit integer ALUs (for most operations) but 64-bit FPUs.

As far as I could tell - by reading Agner Fog's tables - it had 2x64-bit, so it could execute a 128-bit integer op with two micro-ops (and probably macro-ops) but in one cycle. Now it seems Jaguar can execute two.

There doesn't seem to be any hints that Jaguar's SSE units have been expanded. You'd think if they did, they would make it easier to find.

It's in the software optimization guide. They(simd pipes) have been expanded and AMD states up to 2x fp throughput versus Bobcat in the manual itself (be it packed integer or pure fp).

Got it. Thanks.

There was this slide:

But yeah, they've not done a great job of the publicity lately. Which is odd- with the PS4 design win, you'd think they'd be shouting about Jaguar from the rooftops!

They go through additional verification, much like server CPUs. Everybody's embedded CPUs cost more than their run-of-the-mill application CPUs. They basically have to put up with cold nights and hot days of being above asphalt in a desert, if not worse. CPUs that might not quite put up with that for years on end will still work just fine in your notebook or HTPC, but you want that assurance for a machine that controls a billboard, FI.
