Dell Inspiron 16 Temps

I recently bought a new Dell Inspiron 16" with an i5 1334u/Iris graphics thinking it would run cool and quiet considering the 1334u is a 15W part, however it idles at around 50'C with the fan always making its presence known. Running CPU-Z's benchmark, the P-cores hit 90'C within a few seconds...

Ryzen 3600 upgrade issues.

I managed to sort the issue by removing one of my RAM sticks, getting it to POST, and then trying different RAM slots until I could get it to POST with both sticks installed. It was a fairly tedious process, but I got it to work in the end with everything set to default in BIOS.

Thanks for the replies. Looks like I'm better off waiting for the next BIOS for my MB before attempting another upgrade.

What happened with "Anaphase?"

Reverse Hyperthreading was a rumour started by Fudzilla/Inquirer and was supposed to be an AMD technology. It seems someone jumped to their own conclusions after AMD started talking about dynamically partitioning resources, as we see in Bulldozer. 'Clustered multithreading' was another example...

phenom 2 x4 940 heat problem on 780g mobo

My situation has pretty much mirrored yours. I went from a 5600+ on a GA-MA790X to my 940BE, cooled by a Zalman CNPS8000. My idle temps (at stock, and with Cool n Quiet doing its job) shot up to 49C, and it will frequently hit the high 60s under load. It seems to me the cooler just isn't up to...

AMD describes multichip module: 12-core Magny-Cours

Intel's MCM Quads utilised the FSB for both memory access and inter-core communication. MCMs, by definition, cannot share cache and therefore cannot communicate via cache. If you read the article, you will see that Magny-Cours will make use of on-package HT links for inter-core...

Triple Channel AM3 Chip in the future?

The extra bandwidth afforded by triple channel DDR3 only really makes sense on i7 platforms, and even then only in select applications that can make use of all 8 threads. Maybe AMD's decision to incorporate a Quad Channel memory controller with Bulldozer is an indication of potential...

Phenom X4 940 Temps & Gigabyte GA-MA78GM-US2H

It sounds like either the heatsink is incorrectly installed, or Cool n Quiet is not running. Core Temp should report a clock speed of 800MHz at idle. If this isn't the case, check your Power profile is set to 'Power Saver' in Windows.

AMD Athlon 64 X2 7750 2.7GHz

I was considering upgrading to this from my current 5600+ @ 3.1GHz, but I'm struggling to justify upgrading to a lower clocked X2 that somehow consumes more power, despite being fabbed on a smaller process. With Phenom II just around the corner, I think I'll abstain.

When will AMD take the crown again?

Probably never. The problem with always being atleast one manufacturing process generation behind is that they can never hit the clock speeds necessary to match or exceed Intel, certainly at acceptable TDP. When Deneb is released, AMD should have a chip that performs nearly as well as Penryn...

"Intel Nehalem benchmarked" (Hexus)

Brisbane or Windsor

If you're upgrading an AM2 system, then an 89W 5600+ will probably suit your needs. If you're building a system from scratch, it's difficult to recommend AMD at the present, especially given how (relatively) little an E8400 for example can be had for.

Memory bandwidth tests... any real differences (part 2)

Why do you expect a gain in performance going from PC5300 to PC8500 on a 333MHz FSB? The aim of your investigation seems to be to determine the performance gain from additional bandwidth, but in both of the above cases the FSB is saturated. A 1333MHz (effective) FSB can handle at the most...

Nvidia or IBM to acquire AMD ?

Personally, I regard the prospect of AMD being bought as more of a necessary evil than a good thing, as come Nehalem, they will find it very difficult to make money. At this point I wouldn't be surprised if they were considering selling off their CPU business entirely and focusing on graphics.

Nehalem

The performance penalty is due to concurrent threads attempting to access the same resources. Granted, Netburst was less than an ideal candidate for SMT given its tiny L1 caches and dismal decode rate, among other things, but Core 2 (and presumably Nehalem) doesn't have unlimited resources...

The performance benefit from SMT on Nehalem will only become apparent once the number of threads of a particular program exceed the number of cores. Nehalem will be released in quad core form initially, so for the vast majority of applications, Nehalem will be faster than its predecessor due to...

AMD 2008 thoughts?

I very much doubt K10's superior thread scaling is due to its single-die design. The X2 was predicted to scale much more linearly than the Pentium D in multithreaded apps, but it didn't; if memory serves, they were roughly equivalent. K10's unganged memory controllers and memory access...

What is holding AMD back from increasing instructions per clock?

In reality, neither AMD nor Intel get anything close to 4 IPC, or even 3. Core 2, like K8/K10, is capable of retiring 3 instructions per clock, but achieves nowhere near this in real world applications. On paper, Core 2 and K10 look equally matched; both can execute 3 Int/Float instructions...

AMD will go down the same 'large cache + IMC' route as Intel with the introduction of Montreal, which will, if rumour is to be believed, have 1MB L2 per core and 6MB L3 per die. An IMC does not, per the misconception, eliminate the benefit of larger cache. An IMC reduces the impact of memory...

I find it baffling. In addition to the 32B instruction fetch and IMC enhancements, K10 essentially includes all the improvements Intel introduced with Core 2, which resulted in 25-30% over Yonah, per clock. The architectural updates implemented in K8 resulted in around 25% over K7, yet here we...

Benefits of 2x1 Mb cache over 2x512?

Benefits of 2x1 Mb cache over 2x512?

As alluded to, real world application performance show a slight benefit, which is usually easily overcome by a 200MHz clock speed increment by an equivalent 512KB core. Having said that, I was surprised to notice an unquestionable increase in general responsiveness when I upgraded to a 5600+...

AT's Phenom review up (11/19)

Phenom's performance is certainly something of a mixed bag. Intel's own benchmarks put Barcelona well ahead of Xeon in HPC and Floating point performance, per clock, which is in direct contrast to performance on the desktop. I'm inclined to agree with other posters here that Anand's Phenom...

Gaming benchmarks aren't really the most reliable method of predicting performance. GPU bound or not, 10% (7% if you compare the average scores) here won't necessarily mean much more than 10% elsewhere. You implied scaling meant that the 3.0GHz Phenom actually performed like an E6600...

Crysis CPU performance: E6850 vs QX6850 vs QX9650 vs Phenom X4

How does performance scaling mean a 10% lag here means much more than 10% elsewhere? Both Intel and AMD are subject to such scaling, and a 10% lag at frequency X will usually mean 10% at Y. Firstly, your reasoning is a little off. CPU performance scaling does not mean that a processor...

Don't expect Nehalem to provide a huge leap in performance on unisocket systems because of its IMC. Intel have largely compensated for the FSB bottleneck through other means, and we certainly won't see the same increase in memory performance as we did with K8, on the desktop anyway. However, as...

First *real-world* benches of Barcelona?

I'd be very surprised if Cloverton was 30% fast per Watt, given K10's power saving features. If K10 is indeed faster per clock, I'd expect it to have a slight advantage in Performance/Watt. 30% per Watt is roughly the advantage Core holds over K8.
