SAPPHIRE Radeon HD 5450 100292DDR3L 1GB 64-Bit DDR3 PCI Express 2.1 x16 HDCP Ready Low Profile Ready Video Card
  • Verified Owner
  • Owned For: more than 1 year

Pros: I own multiple AMD/ATI Radeon HD 5450 cards from Sapphire, XFX and PowerColor. All the cards meet my needs (I'm not a gamer). My heaviest demand is Windows Media Center (MCE).

The Sapphire (I own two) and PowerColor have 1GB of DDR3. The XFX has 512MB of DDR3.

Other than the amount of DDR3 RAM, I thought the cards would be identical. Boy was I wrong.

I am posting my results, comparing the three vendors.

Cons: Using CPUID HWMonitor all four card cores run at 650 MHz.

The DDR3 on the two Sapphire cards run at 667 MHz (above spec); the XFX DDR3 at 533 MHz (at spec); the PowerColor DDR3 at 400 MHz (below spec). All the cards are 64 bit, so card specs double the MHz.

The Sapphire and XFX reduce the core and DDR3 MHz under light load (to reduce power and heat). The PowerColor remains constant at 650 and 400 MHz.

Running the same (real life) workload (Windows MCE), the Sapphire utilization is ~28%; the XFX ~58%; the PowerColor ~60%.
The Sapphire operates at ~47C; the XFX ~43C; the PowerColor ~49C.

From visual inspection, the Sapphire has the largest heat sync (it wraps around the card). The XFX heat sync is smaller (only extends above the card). The PowerColor has the smallest heat sync.

Windows Experience Index (Desktop Graphics, and 3D Business and Gaming): Sapphire (4.5 and 6.1); XFX* (2.7 and 5.4); PowerColor (3.4 and 5.7). * Note the XFX card only has half the DDR3.

Other Thoughts: By nearly every metric I measured, the Sapphire is the best; the XFX a near second (given equal DDR3); the PowerColor a distant third.

I rate only two Eggs mostly because the DDR3 is not to Spec.

NETGEAR EX7000 AC1900 Wireless Dual Band Gigabit Range Extender
  • eggxpert iconEggXpert
  • Owned For: 1 week to 1 month

4 out of 5 eggs NETGEAR EX7000 AC1900 07/09/2015

This review is from: NETGEAR EX7000 AC1900 Wireless Dual Band Gigabit Range Extender

Pros: 1. Came out-of-the-box with Firmware Version V1.0.0.30_1.0.72. I updated to New Version 1.0.0.32_1.0.84.

2. The device supports two modes (Range Extender or Access Point). I did most of my testing in Access Point mode.

3. Dual Band (2.4 and 5 GHz).

4. Setup is easy using your web browser, no software is required. You first select either Range Extender or Access Point mode, then enter your WiFi SSID, Password, etc. There are not many of setup menus (can be viewed as a Pro or a Con).

5. The EX7000 looks nice, is reliable, and provides reasonable range and performance.

6. Range Extender mode supports "FastLane". You connect the EX7000 to your Router via either the 2.4 GHz or 5 GHz Wifi band, then connect your WiFi devices to the EX7000 on the opposite band.

7. One USB 3.0 port. You can attach Storage or a Printer. Media Server support.

8. Both the manual and installation instruction sheet contain the following (misleading) notations:

[a] After the *Range Extender* is connected to your existing WiFi network, you can connect wired devices to the extender using Ethernet cables. Those devices can then access your existing network through the extender’s WiFi connection.
[b] Note: In *Access Point* mode, you can connect your computer or WiFi device to the extender only using a WiFi connection.

Note [b] lead me to believe (in Access Point mode) the Wired Ethernet ports on the device could not be used (other than to attach the device itself to your network).
I was happy to find (why I listed this as a Pro) all five Wired Ethernet ports are active. The other four ports act as a Gigabit switch (when in Access Point mode). Performance is excellent on the Wired ports acting as a switch (they bypass WiFi altogether).
However, the device's GUI URL (www.mywifiext.net) does not work on devices attached to the Wired ports. This is minor since you can manually type the device's IP address (i.e. 192.168.x.y) to access the GUI.

9. One year Warranty, with free 90 day technical support. Register your purchase at my.netgear.com.

Cons: 1. The EX7000 is a bit expensive.

2. NetGear Routers (e.g. the R6300v2) provide Wireless Access Point functionality, as well as functioning as a Router. Unclear why the EX7000 does not support the Router function (i.e. support three modes: Router, Range Extender, Access Point). Likely the hardware supports all three, the firmware limits support to the latter two.

The R6300v2 also support "Bridge Mode" where you connect one Router to you modem; a second router connected Wireless to the first Router; and various devices connected Wired to the second Router in "Bridge Mode".
I haven't investigated if "Bridge Mode" also supports various devices connected Wireless to the second Router in "Bridge Mode", which would essentially be Range Extender functionality.

3. The EX7000 can either be laid flat, or standing up on one end. A stand is provided for the latter.
The Power, WPS, and Reset switches, as well as the five Wired Ethernet ports and the three antennas, are all on the same side of the device. Its a bit crowded, but makes sense if you lay the EX7000 flat (i.e. all the "noise" is in the back).
If you stand the device on end, all the "noise" is on the side (quite visible). The Ethernet cables can get in the way of adjusting the three antennas.

Other Thoughts: 1. These items are different from typical WiFi devices (maybe good or bad for you):
[a] The Login setup asks for an email address, password, and two security questions (as if you are setting up an online ID).
[b] The Status lights are all on the top/front of the device (e.g. not next to the Ethernet Ports like the typical Switch or Router).
[c] The Setup menus are different than what you expect/get with other devices.
[d] The Serial number, PIN, MAC address, etc. are on a "card" you slide out (like a drawer) not on stickers.

2. There is a great Android App provided by NetGear called: WiFi Analytics. The App provides six displays of your WiFi network (for either the attached SSID of all SSIDs).
[1] Signal straight (in dBm) of the attached WiFi SSID.
[2] Signal straight (in Mbps) of the attached SSID. Separate display lines allow you to save the information as you move from room to room.
[3] Channel Number and Signal Straight (in dBm) of all WiFi SSIDs seen in a Scan (shown as a bar chart).
[4] Similar information as #3, but shows you if any SSIDs share the same Channel.
[5] Similar information as #3, shown as a histogram (X-axis is Channel Number, Y-axis is Signal Straight). You filter on SSIDs of interest.
[6] Similar information as #3, shown as a running graph (X-axis is Time, Y-axis is Signal Straight). You filter on SSIDs of interest.

I felt the most useful was #6 as I walked from room to room, however #4 and #5 make it obvious if you need to change WiFi Channel Numbers.

3. Also see my 9/22/2014 review of the EX2700 (NewEgg product N82E16833122616).

In general, I recommend the EX7000 if you need a high end, dual band, WiFi Range Extender / Access Point (unless you can re-purpose a Router).
