Intel Medfield SoC Specs Leak

MrSeb writes "Specifications and benchmarks of Intel's 32nm Medfield platform — Chipzilla's latest iteration of Atom and first real system-on-a-chip oriented for smartphones and tablets — have leaked. The tablet reference platform is reported to be a 1.6GHz x86 CPU coupled with 1GB of DDR2 RAM, Wi-Fi, Bluetooth, and FM radios, and an as-yet-unknown GPU. The smartphone version will probably be clocked a bit slower, but otherwise the same. Benchmark-wise, Medfield seems to beat the ARM competition from Samsung, Qualcomm, and Nvidia — and, perhaps most importantly, it's also in line with ARM power consumption, with an idle TDP of around 2 watts and load around 3W."

    Intel Medfield 1.6GHz currently scores around 10,500 in Caffeinemark 3. For comparison, NVIDIA Tegra 2 scores around 7500, while Qualcomm Snapdragon MSM8260 scores 8000. Samsung Exynos is the current king of the crop, scoring 8500. True - we're waiting for the first Tegra 3 results to come through.

    But the same paragraph says

    Benchmark data is useless in the absence of real-world, hands-on testing,

    If the performance figures are realistic this is one fast processor, and it appears to be a single core chip, (or at least I saw nothing to the contrary). That's impressive.

    Single cores can get busy handling games or complex screen movements, leading to a laggy UI. If they put a good strong GPU on this thing you might never see any lag.

      I scoured your post for one actual reason why you think x86 is an inferior ISA, but I couldn't find any. I'll give you a couple reasons why it is superior, or at least on par with, any given RISC ISA, on its own merits, not taking into account any backwards compatibility issues:

      • Variable length instruction encoding makes more efficient use of the instruction cache. It is basically code compression, and as such it gives a larger effective ICache size than a fixed length instruction encoding. Even if you have to add marker bits to determine instruction boundaries, it's still a win or at least a wash.
      • x86 has load-op instructions. Load-op is a very, very common programming idiom both for hand written assembly and for compiler generated code. ARM and other RISC ISAs require two instructions to accomplish the same thing.
      • AVX, the new encoding from Intel and AMD, gives you true RISC-like two source, one non-destructive dest instructions.
      • Dedicated stack pointer register allows for push/pop/call/return optimizations to unlink dependence chains from unrelated functions. With a GPR-based stack, RISC has false dependence problems for similar code sequences that they can't really optimize,
      • AMD64 got rid of cruft, added more GPRs, and added modern features like PC-relative addressing modes, removing that advantage from RISC too.
      • ARM's 64 bit extensions were just announced and won't be shipping until 2014. x86 has been 64 bit for 8 years.

NEON, maybe? Or one of the two different sorts of FPU? That's already a significantly complex instruction decoder. The x86 microcode-for-uncommon-instructions approach is probably better.

      Whenever this topic comes up, the discussion is immediately flooded with ARM fanboys insisting that x86 can never compete for magical reasons that don't stand up to sensible analysis.

If the GPU cannot quickly fill pixels, more of the preparation of a frame has to be offloaded to the CPU.

Back in the 90s when transistor budgets were tiny, RISC was a win. When you only have a hundred thousand gates to play with, you're best off spending them on a simple pipelined execution unit. The downsides of RISC has always been the increased size of the program code and reduced freedom to access data efficiently (ie with unaligned accesses, byte addressing and powerful address offset instructions). With modern transistor budgets it is worth spending some gates to make the processor understand a compact and powerful instruction set. That way you save more gates in the rest of the computer than you spend doing this (ie in the caches, databuses and RAMs).
