New variation of ZenPad S 8.0 (Z580CA) added on Asus.com

zenpad-s8-z580-reviewAsus has been known for slight tweaks to their products and thus have many “variants”. If you look at the most recent Zenfone 2, there were a terrific number of ZE551ML variations. Different RAM sizes and storage sizes depending on your country. In the US market, there was only 2 models to choose from. In India there are many available Zenfone 2 models (variants) to choose from as an example.

The reason we’re talking Zenfone 2 is just to illustrate a point. It quite possible that the ZenPad S 8.0 (Z580CA) will have slightly different configurations depending on your country. That’s the only way to explain a recent addition to the official Specifications page on Asus.com which shows the following:

CPU

  • Intel Atom Z3580 Quad-Core, 64bit
  • Intel Atom Z3560 Quad-Core, 64bit

At the original unveiling, there was no variant with a slightly slower Z3560 processor. However, clearly there will be a Z580CA with that slower processor.

So what is the difference between the Atom Z3580 vs. Atom Z3560? Well, the Z3580 is clocked at 2.3GHz and the Z3560 is clocked at 1.83GHz. So that’s a fairly different spec. Does it take the hero out of the hero product? That’s up to you to decide.

It’s unclear if the two processors will be available in the same country, and thus have a cheaper variant available. For some, that might be nice. If you can save a few dollars and enjoy the added features of the Z580CA, then it’s something to consider. Stay tuned for updates!

    I am more worried about the WiFi. So far the only variant with through FCC testing that shows a Z3560 is under P01M. It has only been tested with WiFi B/G/N and only lists a Broadcom BCM4343S chip that only supports B/G/N. The WiFi band support is listed with an asterisk “*1: May vary by SKU and country”. In fact all of the tablets recently run though the FCC (P01Y, P01Z) have only G band listed in the channel declaration documents. Many of the hotspots in my area support A band. No 5GHz band coverage would be a show stopper for me. I hope there will be another FCC submission. I think it would be a poor decision by ASUS not to offer A band in the US.
    I can live with a processor slower variant if it keeps the price down. Remember, this is the burst rate, not the base rate. The IC’s price differential is usually based on speed grade and yields go up the longer the part has been in production. I looked at the Dell Venue 8 series 7000 that has a Z3580 and the same number of pixels. It was very responsive.

      Hopefully, ASUS is just running down a technical issue with the A/AC version(s) and will have it solved on the next card re-spin. I have done three 802.11 designs and can tell you this stuff is hard. I could bore you to tears with the details of spurious emissions, spectral mask, RF sensitivity, … “IF” this is the case, I would not expect a release of product until one month after it gets through FCC.
