** Related to Comparison LGA 771 Xeon vs Pretty Much The Only Opteron Competitor, the 1389 2.9Ghz Suzuka Quad Core...

If anyone has super cheap old tech AMD or Xeon please post results for comparison and build pics.

@Tnlgg 4.7Ghz Nice dude must be one heck of a motherboard... post pics if you would? Also CPU Cache Memory Benchmark as well
thumb.gif


I'll try and line up an R15 run once I get VRM cooling and EPS 8-pin hooked up.

I'm on a stock cooler with an AVC 80mm "Delta Fan" is all nothing special at all... didn't touch any voltage except vcore when all the settings are dialed in just right...

This CPU is working fine at 3.5 to 3.7 to maybe 3.8Ghz on stock voltage... Even 4Ghz was only showing 42-45C Core load temps on a stock cooler. Pretty nice.

Plus I'll be on 32GB ram soon which is gonna be extra sweet all on a crazy low budget...

I just got the Opteron 1389 up to 4Ghz but no board VRM cooling, shuts down during heavy stressing... well "light" per say... AIDA CPU Cache Memory benchmark errors out a couple minutes in and system "Restarts" basically... If I had the EPS 8-pin power hooked up I'm sure it would be more stable... Only hooked up EPS 4-pin to the 8-pin connector... Need to do some PSU swapping. Not to mention thermal adhesive OTW for VRM heatsinks...

60 grams thermal conductive adhesive 1.5W/m K only like $4...

Took 1.45v vcore alone to get into windows and anything higher isn't helping much...

this are my numbers.


Daily use, not Overclocked profile. Just stable settings (linx stable).

This battle is gonna be epic, xDD. Unfortunately my X5460 will not do as good as Tnlgg's X5470, but it's almost equal in Cinebench R15 at 4,5ghz. .The other day i managed to get it pass 4,6ghz at 1,4650v , so with a bit of tweking, and with a little help of DDR3 , i can win that battle, xDD.

should we try Cinebench R15, SuperPi, Geekbench 4 for synthetic results? that would give us a good idea of the performance.

Please add better quality pics,cant see anything.

My "Daily" use is 4GHz,gaming at 4.6GHz.

I use DDR2 & you DDR3,so even if you tweak it you wont win since i can get my X5470 up to 4.8GHz+.

Would love to see some game benchmarks with Opteron vs Xeon,test a few games at max settings.

Oh yeah to view "Large Image" .... Right Click Open Image In New Tab...

Can we compare the same Ghz? To see if the opteron is doing okay like in comparison to xeon? like 3.7-3.8-3.9 comparison?

Lets compare 3dmark03, 06, vantage? default

I might add it's really interesting I noticed the Opteron or maybe AMD chips score as high as they are clocked... 321 points for 3.21ghz... now 3.72ghz for 372 points... strange.. means 500 points need 5ghz... kinda a coincidence

Yeah my cpu here hit higher temperature than I ever saw and vrm reported 67C which is too hot on these... it's hotter than 67C most probably... I just went from default 1.325v to way too much over-zealous 1.45v just to run it the first time.. Hilarious 3.7Ghz crashed at first and some how not only corrupted the Cinebench unzipped folder but also the fresh downloaded .zip Cinebench r15 archive.. re downloaded and made two archive copies this time haha....

This is just a 1st time run through.. I need to add VRM cooling and water cool the Opteron hahaha .. I have a 120mm radiator just need to get some 91-99% isopropyl alcohol to mix (I do this on my car radiator keeps the block insides like crystal clean and the water pump not to mention higher bowling point by like 100F maybe) like 1/90 or 10/90 with 90% distilled to keep the AIO loop crystal clear continuous maintenance free... Also need to figure out most proper way to fill... without a bleeder screw? Anyone advice AIO filling and if some air exists is it okay? I also sorta kind wanna drill and tap a threaded hole (but if I don't have to that's much preferred) in the top of the radiator to add a bleeder nipple to belch it after sealing haha... That AIR!! haha arghhh .. LMK?

372 Cinebench Weak Cheese Opteron.. It games like a Champ though and I only tend to like 4-5k with it... I can deal 30fps no biggie at 5k so beautiful rx 480 8gb.

I feel like I'm dealing with the same issues Ryzen is it's like the cpu fan ramps up VRM is hot CPU is Hot it's like not what I'm used to .. ultra silent Dual X5650 24 threads of silence power .. haha which scores 1332 Cinebench r15 last I checked.

So I've done more testing the Opteron 1389 doesn't like anything more than DDR3-1432mhz, not voltage or timings would fix this. I tried DDR3-1439mhz no go. DDR3-1432mhz no problem.

I also found out that Cinebench R15 scores revolve around not only the clock but the perfect marriage between the clock and memory timings, not the speed of the ram but the timings in accordance to core clock.

By running too loose timings for the core clock/ memory clock yields less... Tighter timings to memory/ core clock yields higher scores... even the tighter you go the higher the score... Which is like a tight window of instability of what Cinebench R15 really likes haha

is the GA MA770t UD3P better or worst than yours?? It can be bought for about 40$. seems worst than yours

Considering an X5460 can be bought for about 17$ and the cheapest 1389 opteron i've seen was almos 40$, opteron seems not cheaper. Maybe you show us where you buy them cheap.

as ddr3, that mem for xeon is not expensive. You can buy my exact same kit, KHX1600c9d3b1k2/8gx second hand for about 40€ and you´ll get a nice performance. in fact, you can buy a 4gb 1333mhz stick in a spanish retailer for less than 22€.

for what i've seen now, and according to numbers, it's to be seen that opteron is a cheaper rig than the xeon counterpart. it's possible that a xeon rig costs a bit more, but almost neglectible amount of difference.
We have to see if opteron can perform better in synthetic than the xeon, which, in numbers, it is outperformed by the xeon. And going for games, we would have to have all three (or more mates), the same graphic card, which is a bit difficult.

The only way of possible comparaison is in synthetic, where it seems opteron does not do well.

if that was true, (i don't really know), that means that that DDR2 of Tnlgg clocked at less timings should do better at Cinebench R15 than my ddr3 since i have looser timings with a bit of more speed.

and that, seems not the rule with Xeons. Maybe with opterons.

Yeah... ebay usa .. 16GB kit DDR2-800 ... $25 USD... 32GB of DDR3-1600 for AMD only $95 USD ... that's a deal... long wait though it's not us only it's coming from over seas way cheaper.

Now what's real real cool about Opteron that I'm sure there will be or should be a huge massive thread on later is the epic G34 Socket Opteron's ... were talking 16-core's bros on one cpu... They are dirt cheap like 8-12-16 threads from like $5 to $29 ... 16 threads $29 G34... It's the boards that are a pain... Only dual socket massive things... maybe some single socket boards will pop up and we'll all be using cheap G34 16-core Opteron's ... can't beat the value.

ebay cpu opteron 1389 is $28... sometimes $25 ... It's the ram which makes it good, that such cheap and highly effective ram that has awesome bandwidth... In a Scenario where memory bandwidth would come to shine is Fallout 4... It loves memory bandwidth and a whole whole bunch of ram... 16 to 32GB ideal... The Xeon's don't do well on Fallout 4 not enough bandwidth and not enough ram... Can't run 32GB on Xeon... Only Dual Xeon at DDR2-667 like 6.5GB/s.. 48GB capacity...

For games that hog down on a whole whole bunch of ram, the Opteron has awesome memory bandwidth and high capacity at a value... Is really what matter most... The Xeon has 550GB/s L1 rate though only 10GB/s on it's big end of memory bandwidth. Opteron call it 3.7Ghz is still like 465GB/s compared to 4Ghz 475GB/s L1... Though 17GB/s memory bandwidth.. between 17-9.5-14GB/s across the ram... Depending on how it's clocked and timed.

If there was a Fallout 4 benchmark that would be a great way to test... Maybe let's resort to AIDA GPGPU test CPU only... I'll test my HD 5850 I have in now.. I modded it up.. Desoldered the DVI and modded the blower which cooled it down a lot... from inaudible fan at 85C to inaudible fan to having a hard time reaching 69C after a long time... Also I clocked it to the max 844Mhz core and 1172Mhz memory stock voltage.. just for fun it was on the shelf and modded it'll be worth using cooler running and more usable for sure.

*Update* Opteron among all AMD chips not including Ryzen show huge improvements across the board when using higher than default Hypertransport : Northbridge Link rates.

From 2104Mhz HT-NB to 2367-something or other is like another 2GB/s across the memory bandwidth. From 15GB/s to over 17GB/s. I also compared Loose to Timing Timings... As seen in above scores of over 17GB/s... These are comparing Loose vs Tight timings.

Cinebench r15, superpi, geekbench 4, cpuz benchmark and passmark are a good way to begin. The only thing is that opteron cannot do well in any test against xeon so maybe there is no point on doing that. 3d mark cpu score can be nice aswell. The big benefit of opteron is ddr3 ram , and even there i can almost get the same result as a newer platform like am3.

I'll post my best results on those mentioned tests.

purchasing aida64 isn't gonna happen(i'm CHEAP) But, here's some comparisons for ya. Note that the 3 4c/4t cpu's listed are all my e5450's scores.

cpu screenshot was after the save,so it overwrote the 3rd lower result(was like 412)
 
#15 ·
note the difference between the i73770 with the gt620 and my e5450 with the mediocre 5770 with a slight OC. kinda makes the point that unless the game is newer and able to take advantage of hyperthreading/more then 4 cores, our xeons are just as good as long as they have the GRAPHICS card to support the game.
morethen double the FPS with half the threads/same amount of cores.

Only real problem with Passmark,is it also uses the hdd test as part of the score.THAT's what usually tanks my scores.

I use old spinning disk drives.

my scores there are barely in the bottom 1/3 if I'm lucky. Will run again and post whole results for ya's.

HAHAHA XML? That's a lot of time but yes I hear ya haha... If we were to create a table specifically on one application among many different systems could work?

Check out HD 5800 series on Opteron 1389 3.8Ghz on 2104Mhz HT-NB link... 73.55fps OpenGL Cinebench R15... idk if it's good or horrible

Which drivers and clocks? I'm only like 1Ghz slower on freq just because of lacking board... but 32GB ram is nice... Need a capable overclocking board to see good numbers...

Your boards are overclocking and of Standard ATX size correct? I'm on mAtx so much smaller. haha

If I used the 990FX I'm sure performance would go up. That's the nice thing about AM3, they kept it for a while.

Cinebench OpenGL benchmark is a rather nonsense bench, for this reasons:

1Âş because it's not an optimized bench.
2Âş All of my 4 cores are used less than 60%. some of them even less than 40% in 4 tests i've done.
3Âş The GPU is used less than 50%
4Âş because in the latest drivers, AMD has implemented something called "chill" that enables the GPU to only show up to 60fps in (which is my case), and this is done with the main purpose of use less power and maintain the GPU better cooled.

there is not a way to disable that option the get the best result there. My result is utterly useless since i know and can probe that this test is not getting the best of my hardware, so no point in posting my result.

Yeah I popped in my RX 480 8GB and the latest and down to 17.1.2 were crashing for some reason? I'm gonna try 16.9.2 WHQL as it always seems to be the best most compatible crash free driver...

Set in AMD Settings 200fps target and "Performance" texture quality... I'm gonna try 16.9.2...

I also swapped the board to my other "identical case" with EPS 8-pin CPU power... didn't seem to change anything over the EPS 4-pin connector in the 8-pin on the board.

On the Opteron front I'm having a lot of issues clocking with 4 modules, 2 modules 4Ghz or more is possible but with 4 modules only up to 3.8Ghz if I'm lucky... 3.625Ghz is totally fine. The memory controller on the Opteron is extra freaky past DDR3-1400mhz... fails to load RAID on 4 modules with 1400mhz ddr3... Though if dialed in 3.625Ghz at 1332Mhz is fine stock voltage. I somehow pulled 2750Mhz Northbridge clock but didn't seem to have the impressive 17GB/s that two modules did. Just about 16GB/s memory. Though the Read or Copy (Can't Remember? Middle One haha) did go up to 10.5GB/s. Not that it matters. I'm at stock right now to troubleshoot this Cinebench R15 OpenGL crash... I wanna get more results up but issues hahaha

By the way I really like the Opteron, just need to speed up my I/O... have a PCIe x1 to x16 ribbon extension to use the x1 slot for either Crossfire or just PCIe x2 Marvell 88SE9230 HyperDuo Controller... So I use an SSD + HDD for around 500MB/s read/ write. Right now the single 7200rpm 160GB drive is not very fast so yeah haha

look, If everyone wants to run the api test from 3dmark and post results, I'll even swap my gtx950 back into the xeon build so it can run the directx12 part of the test. (After all, draw calls ARE an important factor in if a cpu can manage newer games) But I'm NOT gonna swap cards outta builds if others(Opteron for example) aren't gonna post similar test results.

lol, remember my poor xeon is back on air cooling now also. the evo212 isn't the most reliable I've seen.
