How Far We’ve Come: 35 Years Of Processing Power

It’s amazing how far we’ve come in the speed of our computing. While MIPs isn’t a perfect benchmark, as it doesn’t account for the efficiency of the instructions, it will do for our simple comparison.   To put the difference the years have made into perspective: 1 second of processing by the current i7 champ would have taken the best 1985 computer over 4 hours 29 minutes!  Another fun comparison is that the new iPhone 4S clocks in at about 5,000 MIPs which is faster than a computer from 1999.

Year Chip Millions of Instructions Per Second
1985 Intel 386DX 11 MIPS at 33 MHz
1992 Intel 486DX 54 MIPS at 66 MHz
1996 Intel Pentium Pro 541 MIPS at 200 MHz
1999 Intel Pentium III 2,054 MIPS at 600 MHz
2003 Intel Pentium 4 9,726 MIPS at 3.2 GHz
2008 Intel Core i7 920 82,300 MIPS at 2.66 GHz
2011 Intel Core i7 3960X 177,730 MIPS at 3.33 GHz

Here’s another fun comparison: an old 8MB vs a new 8GB (8000MB) memory card:


PyTivo Install Instructions

I love pyTivo but the windows install instructions are getting a bit spread around for new users… so here’s the best I could bring it together:

  1. Download & Install Python 2.x using defaults (3.x doesn’t work)
  2. IF you want to use the photo plugin (requires 32bit Python) install it too
  3. Download & Use the outdated but setup friendly windows installer
  4. Download the latest .zip version (top right of shortlog) of pyTivo to updated the files from #3
  5. Shut down pyTivo if running (may be running as a windows service)
  6. Extract the .zip over the existing \Program Files\pyTivo\ (this should overwrite the old files)
  7. Grab the latest build of ffmpeg (currently 1.01) from 2nd post in this thread
  8. Extract the .zip and overwrite the old ffmpeg.exe in \Program Files\pyTivo\bin\
  9. IF you want to be able to push .tivo files grab the special version of tivodecode in this thread
  10. Drop tivodecode into \Program Files\pyTivo\bin\.  To use tivodecode you must set your Media Access Key in your pyTivo.conf under the Server section (“tivo_mak”).
  11. Add a Windows Firewall exception for UDP 5353 so that Windows won’t block pyTivo’s new zeroconf share announcements.  (The most common reason pyTivo shares don’t show up or disappear from the Now Playing list on the Tivo is firewall blockages)
  12. Move the pyTivo.conf file from \Shared Documents\pyTivo\ to \Program Files\pyTivo\
  13. Startup pyTivo & enjoy!

rdian06’s Notes: In later wmcbrine versions, the web interface has been restructured. The web admin plugin has been split into two parts: configuration and TivoToGo. Likewise, the Push and TivoToGo interfaces are hidden by default.

  • An Admin section is no longer needed in your pyTivo.conf you may remove it.
  • To make the TivoToGo web interface visible, you need to add your tivo_mak and togo_path to the Server section of the pyTivo.conf.
  • To make the Push web interface visible, you need to add the tivo_username and tivo_password settings to the Server section of your pyTivo.conf.

Without those settings, the TivoToGo and Push parts of the web interface are not usable and therefore automatically hidden.

Longitude and Latitude on Google Maps the Easy Way

There are times in life you want to find the longitude and latitude of a known location.  Google maps does everything else well – why not this?  Soon you discover that what was once a feature of GMaps is now gone.  Searching the web brings up a way to center the google map and grab the url and paste it into a javascript and … who has time for all that nonsense???

Here’s the easy way:  Go here and click on the map. Done.

You can even change the default location by clicking the “set” button and bookmarking the new url.

iPad Alternatives

Today is the day that many have longed for since the announcement of the ifamous iPad! However if you are less than impressed with the XL iPod Touch… I have compiled a pretty complete listing of your other options that are currently -or soon to be- out.

To limit the scope of an otherwise giant listing, I have only compiled slate style (keyboardless) devices with screens of 5 to 12 inches.  If I missed one let me know at staff [at] this and I’ll add it in.

We’ve added a link at top of the site for easy reference.

Alienware m11x Initial Review

m11x-mini.jpgAfter playing with -er- using the m11x for over a week, I can safely say that this is one of the best 11″ notebooks ever created.  I still have more testing to complete because multiple styled battery tests are not only boring – they are time consuming.  However, I feel like I have enough good data -beyond my first impressions– to help those in the market for a portable yet powerful notebook to make a better decision.  I’ve included comparisons to my desktop, Adamo, and netbook to give you a good feel for how this pocket rocket performs.   Below are the specs for my machine:

  • 1.3GHz Intel SU7300 (800MHz FSB, 3MB Cache) overclockable to 1066MHz FSB (1.73GHz)
  • Nvidia GeForce GT 335M Discrete Graphics (1GB GDDR3) with switchable Intel GMA 4500MHD integrated graphics
  • 4GB PC3-8500 DDR3 (2 x 2GB)
  • 250GB 7200RPM SATA Hard Drive
  • 11.6″ WXGA WideHD LED Backlit display (1366×768)
  • Windows 7 Home Premium 64bit
  • 802.11b/g/n, 10/100 LAN
  • 3-in-1 card reader
  • 8-Cell Li-ion 64WH battery, 65W Power Supply
  • Dimensions: 11.25″ x 9.19″ x 1.29″
  • Weight: 4.48lbs

First off, let’s address the 3D Marks issue. Engadget reported a “3DMark06 score [of] 5593. That’s significantly lower than the ‘over 6,100’ Alienware claims…” What they missed however was the ability to overclock the m11x in the bios.  A super simple procedure of F2-ing to reach the bios and changing the”OverClock” setting (under Advanced) from “Disabled” to “Enabled” handles overclocking the CPU from 1.3Ghz to 1.73Ghz.  This 33% speed increase is quite noticeable and is required to hit (and exceed) Dell’s claimed 06 marks.  Note: using the overclock option almost ensures the fan will be active in Intel graphics mode.  Using the GPU will kick the fan on as well, but you already knew that going into any gaming laptop.

3D Marks 06
C2D 1.3 Ghz Intel 674
C2D 1.73 Ghz Intel 737
C2D 1.3 Ghz Nvidia 5605
C2D 1.73 Ghz Nvidia 6429

Real world gaming is always the most grueling part of any review, but I suffered through it for you.  ;)  This thing can actually play Crysis at native resolution.  Stock CPU, it can handle the low settings without problems at 1355×768 and looks quite nice doing it.  Overclocking allows a bit more eye candy but not enough to enable full medium settings.  Less ridiculously intensive games do much better at native resolution:

  • Unreal Tournament runs fine at default (high) settings.
  • Far Cry 2 can be played at medium settings when overclocked.
  • Call of Duty 2 can be played at maximum settings which includes an in game 4x AA and generally see between 50-80 FPS stock or 60-90 FPS overclocked.
  • The original Call of Duty is old enough that it can’t support the native wide screen res and forces you to drop back to 1024×768.  With max setting and nHancer set 4×4 AA and 16x AF you generally get 70-200 FPS without overclocking but intense action with large explosions can cause a dip down to 30 FPS at these extreme settings.

The overclocking is noticeable in CPU intensive tasks such as video encoding or calculating prime numbers.  I ran wPrime several times after a reboot and took the best time.

wPrime 32M in Seconds
i7 Core 3.21Ghz (Desktop) 8.97
m11x C2D 1.73Ghz 55.7
Adamo C2D 1.4Ghz 62.4
m11x C2D 1.3Ghz 68.2
Asus Atom 1.8Ghz 125.7
Asus Atom 1.6Ghz 134.4

Besides CPU, the other common bottleneck in ultralight computers is often slow hard drives.  SSDs can greatly improve this area not only in data transfer speeds but also in access time.  A note on the HD Tune results for the m11x that was not overclocked:  You will notice the abysmal 7MB/sec minimum.  Running the test 3 times I got the spikes of slowness 2 out of the 3 times.  Now those spikes will happen on not-completely-sanitized machines when the antivirus or some other background process grabs a few clock cycles or hit’s the disk momentarily.  So they are to be expected and should not be inferred to mean bad, bad things.  You will notice this very low min did little to change the average speed of the drive compared to the overclocked tests.  However, after using the m11x for a week, I can attest to the real world reflection of these results.  The m11x for the most part is adequately  zippy even considering the fact that I’m accustomed to my ultra-fast workstation.  However at times it seems the slower CPU and HD bog down at the same time and performance grinds to a halt for an agonizing second or two.  Consider your normal notebook taking a “union break” and pretending it’s a netbook for a few seconds and then returning to normal.  Perceived speed is relative but the difference is there even compared against itself.  The good news is that I have not yet seen this happen while the CPU is overclocked.  Granted you can still overtax the CPU easily with intensive tasks but that is a different matter.  OC’d it doesn’t seem to have the odd random slowdown.

Asus 1000ha 1.5 57.8 34.4 19.7

The chart above is arranged by access time as that often is a more noticeable in how fast a computer feels.  Fast transfer rates can help during an a program install or copying a large video file.  Fast access time helps everything – especially launching applications where many small files must be brought together to load the program.  For this “speed feel” test Gimp was used as it is a big slow program to load which gives a nice worse case test and makes it easier to time with a stop watch.  The test was repeated several times and the best time was taken.  However only the first launch after each reboot was used as after that cache skews the results (for instance a 2nd launch following the first for both the Adamo and the m11x completed in under 8 seconds when caching all but eliminated hard drive speeds from the equation)

Gimp Load Time in Seconds
i7 Core Desktop, Intel SSD 2.8

m11x C2D 1.3Ghz, 7200 HD 18.4
Asus Atom 1.8Ghz, 5400 HD 25.4

Even with the faster 7200rpm HD option from Dell and a faster CPU clock speed, the Adamo’s even faster SSD allows for a significantly zippier user experience in Windows.  Dell offers an SSD upgrade but unfortunately it’s $570.  Now the good news is that it is 256GB which is large as SSDs go.  The bad news is that OEM SSD – as seen in my Adamo – don’t tend to live up to the Intel benchmark of SSD speed.  However, drives are not that difficult to upgrade, so you can always grab a top performing SSD later and spread out the payment pain a little as well.

Finally battery life.  I am still running a battery of tests (heh heh) but I can report that the battery is quite strong.  In fact, I believe that the majority of the weight difference between this machine and other “thin and lights” is actually battery weight not the GPU or fans. At the request of my friend Brad over at liliputing, I have run battery tests on HD video use first.  Interestingly, the results are almost identical with the Core2Duo running stock or overclocked. Apparently the power draw of the CPU running 60-80% is the same as the CPU being overclocked and running 50-70%.  The back light was way too dark at the lowest setting but was quite nice at the 2nd of 8 setting so it was used.  Although the differences between the rest of brightness levels does not seem to be very much, especially considering there are only 7 (not dark) settings. Wifi was on and sound was at 30% for this test. As the m11x has no CD/DVD drive, an iTunes HD video seemed a likely candidate for quick and easy video on the go.

  • iTunes HD Video Battery Test: 10% warning with 22min windows estimate at 3:32 or 3hr 54min total
  • iTunes HD Video Battery Test (OC’d): 10% warning with 24min windows estimate at 3:31 or 3hr 55min total

Or enough time to watch 6 Psych episodes with time to spare.  From general use, I can also tell you’ll see 2+ hours of gaming and 6+ hours of light, gentle use.  I flesh will out those numbers with further testing and include them in my complete review in the days ahead.

Until then let me just say that the balance between power (CPU & GPU), portability, and battery life in the m11x makes it quite a compelling offering.  It is well worth the extra money over the many CULV Thin and Lights out there.  As it is alone in it’s offering of an overclocked CPU and a best in class GPU (true mid-range for gamers), it is easy to call this the most powerful 11″ notebook you can buy.  For the power user wanting a bit more, an upgrade to an speedy (non OEM) SSD could make this thing really rock at a still cheaper than some price.
